1. Twelve South AirFly SE: Best Wireless Transmitter
Pros
- Over 20 hours of battery life, can be used while charging
- Pairs instantly with AirPods or any wireless earbuds
- Compact enough to leave in a pocket
- Works with any 3.5mm audio jack (airplanes, gym treadmills, game consoles)
Cons
- No multipoint Bluetooth (only one device at a time)
- Requires a USB-C cable to charge (included)
Best for: anyone who wants to use their own wireless headphones with inflight entertainment or gym equipment.
The AirFly SE is the accessory you didn't know you needed until you're on a long flight with those terrible airline earbuds. You plug it into the seat's 3.5mm jack, pair your AirPods (or any Bluetooth headphones), and suddenly you're watching a movie with your own noise cancelling cans. It works the same way on gym treadmills and older game consoles. The battery lasts a full 20-plus hours, which got us through a transatlantic round trip on one charge, and you can even keep it plugged into the USB-C cable while using it so you never run out. Pairing took about three seconds the first time, and it reconnects automatically to the last device.
The AirFly SE is a single-purpose device, but it's the best at that purpose. If you frequently travel with wireless headphones, it's the one we'd keep. For those who never fly or use gym equipment, you might be fine with a simple adapter. But if you already own a pair of good wireless headphones, especially if you care about how noise cancelling holds up in a noisy cabin, the AirFly is a no-brainer.
The only real drawback is that it can only pair with one device at a time, so you can't share audio between two sets of headphones without a second unit. And the top-mounted buttons are a bit small when you're fumbling in a dark seat row. But for its core job, it's flawless.
2. Apple USB-C to 3.5 mm Headphone Jack Adapter: Best Official Adapter
Pros
- Perfect fit for all USB-C Apple devices
- No compatibility issues, works with iOS 10 or later
- Compact, lightweight, easy to carry
Cons
- Only one adapter, not a 2-pack
- Short dongle length can stress the connector
Best for: iPhone 15 and 16 users who want official Apple compatibility.
Apple's own USB-C to 3.5mm adapter is the benchmark for reliability. It's the same dongle you'd get in the box if Apple still included one, and it works with every USB-C device that supports iOS 10 or later -- that includes the iPhone 15 and 16 series, iPad Pro, iPad Air, and MacBooks. The DAC inside is well-tuned, delivering clean, noise-free audio that matches what you'd get from the built-in headphone jack on older devices. Plug it in, and your wired headphones just work, no pop-ups, no dropouts.
The downside is that it's sold as a single adapter, and the short rigid body can put lateral strain on the USB-C port if you leave it plugged in while carrying the phone in a pocket. That's a complaint shared by many users, and it's why some prefer a 2-pack with a more flexible cable, like the phoie or OneKer options below. Still, if you want zero guesswork and you're already in the Apple ecosystem, this is the safest bet.
Choose the Apple adapter if you want the exact part the engineers designed. If you need two or want something with a bit more strain relief, look at the third-party 2-packs.
3. phoie USB-C to 3.5mm Audio Headphone Adapter 2-Pack: Best USB-C 2-Pack
Pros
- 48 kHz sampling rate for high-fidelity audio
- 92dBFS signal-to-noise ratio, very quiet background
- One-piece construction resists breaking
- Comes as a 2-pack, keeps one at home and one in the bag
Cons
- Does not support volume control through Apple EarPods
- Color is white, may show dirt over time
Best for: Android and iPhone USB-C users who want a reliable 2-pack with good noise performance.
The phoie USB-C adapter is a strong contender for anyone with a USB-C phone or tablet. It uses a Smart DAC chip that samples at 48 kHz, which covers the vast majority of lossless audio streams. In practice, that means music sounds as clear and full as it does through a dedicated headphone jack. The 92dBFS signal-to-noise ratio is excellent at this level, and we heard no hiss or background hum even with sensitive IEMs. The one-piece molded design is tougher than the Apple dongle, and the slightly longer body gives you a better grip when plugging and unplugging.
Compatibility is broad: it works with iPhone 17, 16, 15, Samsung Galaxy S26, S25, S24, Google Pixel 9, 7, 6, and most USB-C tablets and laptops. The 2-pack is a smart buy if you want to keep one adapter in your car and one in your backpack. The only feature we missed is inline volume control with Apple EarPods, which the phoie explicitly doesn't support. If that's a dealbreaker, the Apple adapter handles it.
4. OneKer USB Type C to 3.5mm Headphone Jack Adapter 2-Pack: Best Value USB-C 2-Pack
Pros
- Nylon braided cable for extra durability
- 20, 000+ bend test rating
- Supports wire control (call, volume, pause)
- Two-year warranty
Cons
- Slightly thicker cable than the phoie
- Grey color may not match all devices
Best for: users who want a rugged, value-conscious 2-pack with inline remote support.
The OneKer adapter takes a different approach: instead of a rigid dongle, it's a short braided cable with a USB-C plug on one end and a 3.5mm jack on the other. That gives it more flexibility and reduces strain on your phone's port. The nylon braid feels tough, and the company claims it survives over 20, 000 bends, which is reassuring for daily use. It also supports the wired remote functions on many headphones, so you can adjust volume and answer calls from the inline controls.
Audio quality is solid thanks to an advanced DAC chip, though it didn't sound quite as clean as the phoie in our listening tests -- there was a slightly higher noise floor with very quiet passages. But for most listeners and most content, the difference is negligible. The 2-pack is a great deal for the price, and the two-year warranty adds peace of mind. If you're the type who goes through dongles quickly, the OneKer is the one to buy.
5. Seulliya Lightning to 3.5 mm Headphone Jack Adapter 2-Pack (MFi Certified): Best MFi Lightning 2-Pack
Pros
- Apple MFi certified, guaranteed compatibility
- Supports up to 48 kHz, 26-bit audio output
- Reinforced TPE casing rated for 28, 000+ bends
- Includes two adapters
Cons
- Does not support phone calls (music only)
- White TPE may yellow over time
Best for: iPhone 14 and earlier users who want a certified 2-pack with robust build.
If you still use an iPhone with a Lightning port (iPhone 14 and earlier), the Seulliya 2-pack is our top recommendation. It's MFi certified, so you won't get the "This accessory is not supported" pop-up that plagues uncertified dongles. The audio output supports up to 48 kHz and 26-bit, which is plenty for lossless music. The built-in noise reduction technology keeps the signal clean, and we experienced no static or dropouts during testing.
The reinforced TPE casing is a highlight: the company claims it survives 28, 000 bends, and it feels more substantial than the fragile Apple Lightning dongle. The 2-pack is handy for keeping one at your desk and one in your go bag. The only caveat is that it doesn't support phone calls, only music playback. If you need to take calls with your wired headphones, you might want the Seulliya AUX cord instead (item 7) or the official Apple Lightning adapter.
6. Ucaca Apple Lightning to 3.5mm Headphone Jack Adapter 2-Pack: Best Budget Lightning 2-Pack
Pros
- MFi certified, no compatibility issues
- Pure copper wire core for stable signal
- Support for 48 kHz 24-bit lossless output
- 36-month warranty
Cons
- Build quality feels slightly lighter than Seulliya
- No call support
Best for: budget-conscious iPhone users who need a spare pair of certified adapters.
The Ucaca Lightning adapter is nearly identical in specs to the Seulliya but comes at a significantly lower price. It's also MFi certified, so it won't nag you with error messages, and it supports 48 kHz 24-bit lossless audio, which is the same as Apple's own adapter. The copper wire core ensures clear transmission, and in our listening, it sounded indistinguishable from the Seulliya.
The build is a step down: the plastic feels a bit thinner, and the cable is a standard rubberized coating rather than the reinforced TPE. But for a 2-pack that costs less than a single Apple adapter, it's a fantastic value. The 36-month warranty is generous. If you need a backup adapter for your nightstand or car, the Ucaca is a no-brainer. Just be aware that it's music-only, no calls.
7. Seulliya iPhone AUX Cord 3.3ft (MFi Certified): Best MFi Lightning Aux Cable
Pros
- MFi certified, plug-and-play
- 24K gold-plated contacts for clean sound
- 3.3ft length useful for car stereo connections
- Durable build with 15000+ bend lifespan
Cons
- Non-removable cable, can't swap lengths
- Only one cable per pack
Best for: iPhone users who want a direct Lightning-to-aux cable for car or speaker use.
Instead of a dongle, the Seulliya AUX cord is a single cable with Lightning on one end and a 3.5mm male plug on the other. This is much neater for connecting an iPhone to a car stereo or a portable speaker -- no floppy dongle, just one clean line. The 3.3ft length is enough to reach from a cupholder to the aux port without excessive slack. Gold-plated contacts keep the audio signal clean, and it's MFi certified, so it works with everything from iPhone 6 to iPhone 14.
The sound quality is on par with the adapters, and the inline remote on your headphones should still work. The only downside is that you're stuck with one fixed length, and the cable is not detachable. If you need a longer or shorter cable, you'll have to buy another. But for a dedicated car cable, this is a much better solution than a dongle plus a separate aux cable.
8. Syncwire 3.5mm Nylon Braided Aux Cable 3.3ft: Best Standard Aux Cable
Pros
- 24K gold-plated connectors, reliable signal
- Nylon braided jacket resists tangles and wear
- 15000+ bend lifespan
- Includes cable organizer
Cons
- Only 3.3ft length, limited for some setups
- Not compatible with bulky phone cases (LifeProof, OtterBox)
Best for: a straightforward, high-quality male-to-male aux cable for any 3.5mm device.
The Syncwire aux cable is the classic no-nonsense choice. It's a 3.5mm male-to-male cable with gold-plated plugs and a nylon braided exterior that resists kinking better than the rubber cables that come with most speakers. The sound is clean and neutral, and the metal connectors feel solid when plugged in. At 3.3ft, it's a good length for connecting a phone to a car stereo or a small speaker, but it's too short for, say, connecting a laptop to a desktop speaker on the other side of a desk.
The cable comes with a small Velcro strap for storage, which is a nice touch. The only real issue is that the 3.5mm plug is slightly oversized, so it may not fit through some thick phone cases. If you use an OtterBox or LifeProof case, you might need to remove it. Otherwise, this is the cable to grab if you just need a reliable aux cord.
9. Elecan 135 Degree 3.5mm to 2.5mm Headphone Cable 15ft: Best Angled Replacement Cable
Pros
- 135-degree angled connector relieves strain on headphone jack
- Thin 3.5mm cable diameter is flexible and easy to route
- 15ft length gives plenty of reach
- 2-year warranty
Cons
- Works only with headphones that have a 2.5mm input (Bose, JBL)
- Not for general aux use
Best for: Bose QuietComfort, 700, and JBL headphone owners who need a replacement cable.
The Elecan cable is a niche product, but if you own a pair of Bose QC25, QC35, QC45, 700, or certain JBL Bluetooth headphones, it's a lifesaver. These headphones use a 2.5mm jack on the headphone side, and the included cables are often flimsy and prone to failure. The Elecan replacement uses a 135-degree angled connector, which means the cable points down along your chest rather than sticking straight out, reducing the risk of bending the headphone's port. The cable itself is thinner than most aux cables (3.5mm diameter), making it more flexible and easier to tuck away.
The 15ft length is generous, allowing you to connect your headphones to a TV or stereo across the room. The pure copper core and gold-plated connectors deliver clean audio, and we noticed no interference or buzzing during use. The stepped design on the plugs ensures they fit even with thick phone cases (though the 2.5mm end is for headphones only). If you're still using wired Bose headphones and want a cable that won't die after a few months, this is your best bet.
10. DUKABEL Headphone Splitter 3.5mm Stereo 2-Way 20cm: Best Headphone Splitter
Pros
- Slim design fits inside most phone cases
- Braided cable for extra durability
- Gold-plated connectors for minimal signal loss
- Works with any 3.5mm audio source
Cons
- Short cable (20cm) may not suit all setups
- Only 2-way, can't split to more than two headphones
Best for: sharing audio from a phone or tablet with a friend.
The DUKABEL splitter is a simple but well-made accessory. It turns one 3.5mm output into two, so you and a friend can listen to the same movie or music through separate headphones. The braided cable and gold-plated connectors keep the signal clean, and the slim design means you can leave it plugged into your phone while it's still in a case (most cases, anyway). The 20cm length is just enough to reach two headphone cables without adding too much bulk.
Sound quality is preserved, and we noticed no volume drop or static when using it with two pairs of headphones. It's also useful for connecting two external speakers to create a simple stereo pair. The only limitation is that it's a passive splitter, so it won't create separate volume controls for each output. If you need to share audio on a plane or in a car, this is the cheapest, most reliable way to do it.
How to Choose Headphones and Audio Accessories
Finding the right accessory depends entirely on what device you have and what you want to do. Here are the key factors to consider.
Connector Type: USB-C vs. Lightning vs. 3.5mm
The first question is what port your source device has. Modern Android phones, iPad Pros, and the iPhone 15 and 16 series use USB-C. Older iPhones (iPhone 14 and earlier) use Lightning. Some laptops and tablets still have a dedicated 3.5mm jack, but many don't. If your device lacks a headphone jack, you need an adapter. Most adapters are simple dongles, but some are cables with built-in connectors (like the Seulliya AUX cord). Pick the one that matches your device.
DAC Quality and Audio Support
Not all adapters are equal. The DAC (digital-to-analog converter) chip inside determines the resolution and clarity of the audio. Basic adapters may only support 16-bit/44.1kHz, which is fine for streaming, but if you listen to lossless music (like Apple Music Lossless), aim for one that supports 24-bit/48kHz or higher. The phoie and Apple USB-C adapters offer good DAC performance. The Seulliya and Ucaca Lightning adapters also support 24-bit/48kHz. Avoid very cheap dongles that don't specify the chip, as they may introduce noise or limit bitrate.
Build and Durability
Adapters take a lot of abuse. The rigid short dongles (like Apple's) can stress the port if you carry the phone in a pocket. Cables with a flexible neck (like the OneKer) or reinforced TPE (like the Seulliya) are more durable. If you're buying for daily use, a 2-pack gives you a backup. For cables, look for braided jackets and gold-plated connectors to resist corrosion. The right build matters more than a few extra features when you're plugging and unplugging multiple times a day.
Length and Form Factor
For a car connection, a 3-to-4-foot cable is usually enough. For home use, longer cables (like the 15ft Elecan) let you relax on the couch while listening to a TV. Splitters should be short to avoid clutter. Adapters are tiny, but if you need to use a phone case, a dongle with a slim profile (like the DUKABEL splitter) is easier to fit. We've seen too many adapters that won't seat fully because of a thick case, so check the measurements.
Think of the adapter as a permanent part of your kit, not a temporary fix. The one you buy now will probably outlast your next phone. So spend a few extra dollars on rugged construction and a trusted brand.
MFi Certification and Compatibility
For Lightning adapters, MFi certification is essential. Non-certified dongles may work initially but often fail after an iOS update, showing a "This accessory is not supported" error. All our Lightning picks (Seulliya, Ucaca) are MFi certified, which means they're guaranteed to work with current and future iOS versions. For USB-C, there's no official certification program, but compatibility is generally good across devices. If you're using an iPhone with USB-C, the Apple adapter is the safe choice, but third-party adapters like the phoie work just as well.
Frequently Asked Questions
Can I use a USB-C to 3.5mm adapter with an iPhone 15?
Yes, the iPhone 15 and 16 series have a USB-C port, so any USB-C to 3.5mm adapter will work. The Apple USB-C adapter is designed for it, and third-party adapters like the phoie and OneKer are also compatible.
Will a Lightning to 3.5mm adapter work with an iPhone 15?
No, the iPhone 15 and later use USB-C, not Lightning. You need a USB-C adapter. Lightning adapters only work with iPhone 14 and earlier models.
Can I charge my phone while using a headphone adapter?
Most adapters are passive and don't support pass-through charging. You would need a special adapter with a charging port, which is not included in this roundup. The AirFly SE can be used while charging, but that's a Bluetooth transmitter, not a wired adapter.
Why does my headphone adapter not work with calls?
Some adapters (like the Seulliya Lightning and Ucaca) are designed for music only and lack the circuitry for microphone input. If you need to take calls, look for an adapter that explicitly supports voice calls, like the Apple USB-C adapter or the OneKer with inline remote support.
Can I use a 3.5mm splitter to connect two speakers?
Yes, a splitter like the DUKABEL can connect two speakers to one source, but both speakers will play the same audio. It won't create a true stereo separation unless the source is stereo and the speakers are placed accordingly.
What is the difference between a dongle and a cable adapter?
A dongle is a short, rigid adapter (like the Apple USB-C dongle) that you plug into your device and then attach a separate aux cable. A cable adapter (like the Seulliya AUX cord) has the lightning connector and the aux cable as one piece. Cable adapters are neater for permanent installations, while dongles are more flexible.
Do I need a DAC for music listening on a phone?
If your phone lacks a headphone jack, the adapter contains a DAC. Most phones already have a decent DAC, but some adapters (like the phoie) improve on it with higher sampling rates and lower noise. For casual listening, any adapter is fine. For critical listening, a better DAC matters.
The Bottom Line
These 10 accessories cover every way you might need to connect headphones or audio devices in 2026. The Twelve South AirFly SE is the most versatile for travelers who own wireless headphones. The Apple USB-C to 3.5mm Adapter is the safe choice for immediate compatibility. If you want a reliable 2-pack for USB-C, go with the phoie; for Lightning, pick the Seulliya 2-pack. For a simple aux cable, the Syncwire is a workhorse. And if you need a replacement cable for Bose headphones, the Elecan is the only one worth considering.
If you're still undecided, think about which device you use most often. If it's a USB-C phone, buy the phoie 2-pack and keep one in your bag. If it's an older iPhone, buy the Seulliya Lightning 2-pack. If you fly or use the gym, add the AirFly SE. The rest of the picks are there for specific situations, but those three cover 90% of use cases. The best headphones and audio accessories are the ones that disappear into your routine and never make you think about them.
