LERTOSEN 2 Pack USB C to 3.5mm Headphone Jack Adapter
Quick take
The LERTOSEN 2 Pack USB C to 3.5mm adapter kit lets you use wired 3.5mm headphones and headsets with USB-C devices. Review feedback points to solid day-to-day audio performance and convenience, especially when traveling, but buyer experience suggests these can be somewhat “consumable” if carried and used heavily.
Pros and cons
Pros
- Plug-and-play design, no drivers or apps needed.
- Designed for USB-C to 3.5mm headphone use, with built-in DAC for high-resolution audio claims.
- Two-pack format is convenient for a spare (for travel or daily use).
- Supports wired audio and call audio with compatible 3.5mm TRRS headsets (with important Apple limitations).
Cons
- Apple 3.5mm EarPods mic and wired control functions are not supported, and volume/call features may be limited.
- Some users report the adapter cable or connection can fail after a few months with daily, pocket-heavy use.
What buyers think
Buyer-review evidence is generally positive for getting reliable audio from a USB-C device, with themes around convenient everyday usability and “works as expected” performance. Several comments highlight that the adapters are useful for travel, especially when you want a dependable wired headphone option instead of relying on Bluetooth or basic airline earbuds.
At the same time, buyer feedback is limited on fine-grain details like audible noise levels or long-term durability. One recurring caution is that heavy, daily pocket use can shorten the adapter’s lifespan, so it helps to treat these as small gear that you might eventually replace.
What this adapter is for
This is a USB-C to 3.5mm (aux) adapter set intended for devices that no longer include a headphone jack. It’s a practical solution if you already own wired IEMs, earbuds, or headsets with a 3.5mm plug and you want to keep using them on a modern phone or tablet.
The two-pack format is also aimed at buyers who want a spare on hand for commuting, flights, or moving between devices.
Key features to know before you buy
Built-in DAC and audio support
The adapter includes a DAC smart chip and is marketed for high-definition audio output. The goal is cleaner sound reproduction with support for high-resolution-style playback settings on compatible devices.
Wired call support (with compatibility caveats)
The adapter is designed to recognize TRRS 3.5mm headphones with a microphone, so it’s positioned for music and calls in apps and games that support wired headset input.
However, there is an Apple-specific limitation: Apple EarPods with a 3.5mm plug are described as music-only, meaning microphone and wired control features are not supported with this adapter setup.
Plug-and-play convenience
These adapters are designed to work without extra drivers or companion apps. In practical terms, that means less setup and fewer connection steps when you just want audio to start immediately.
Connection design and portability
The unit uses a compact dongle form factor and is intended to reduce repeated plugging and unplugging by keeping a spare. That said, durability can depend on how often you carry and manipulate the cable, so it’s smart to handle it like small audio gear rather than something that will survive rough pocket conditions forever.
Compatibility: which devices and headphone types fit best
Compatibility is broad across common USB-C phones and tablets, including iPhone models that use USB-C, iPad Pro/Air models, and many Android USB-C devices and laptops.
For headphones, the key differentiator is the connector type:
- 3.5mm TRRS headsets with microphone are the intended match for call audio.
- Apple 3.5mm EarPods are limited to listening only, with mic and wired control functions not supported.
Pros and cons summary
Best for
- USB-C phone or tablet owners who want to keep using wired headphones and IEMs.
- Travelers who want a reliable wired option without dealing with Bluetooth battery swapping.
- Buyers who like having a spare dongle ready for another device or backup use.
Who should avoid it
- Anyone counting on Apple 3.5mm EarPods mic or wired control features, since music-only behavior is expected there.
- People who repeatedly bend, roll, or heavily pocket-manage the dongle daily, if they need long-term durability from a small adapter cable.
Price and availability
It’s positioned as a budget-friendly, two-pack accessory. If you mainly need a spare for travel or occasional wired listening, the bundle approach can be a sensible value. If you rely on it daily with heavy cable handling, plan for the possibility of sooner replacement.
Verdict
The LERTOSEN 2 Pack USB C to 3.5mm Headphone Jack Adapter is a practical pick for USB-C users who want wired audio back on their devices, with review sentiment leaning toward reliable everyday functionality. The biggest thing to check is your headphone type and, for Apple EarPods with a 3.5mm plug, be prepared for music-only limitations. If you want a spare for travel or multi-device switching, the two-pack format is a clear advantage.
FAQ
Does this adapter work with iPhone and USB-C iPhone models?
It’s designed for USB-C compatibility, including iPhone models with USB-C. Plug-and-play use is intended, with no drivers required. For specific button or microphone features with Apple EarPods, see the next FAQ.
Will it support the microphone on 3.5mm wired headsets?
It’s intended to support TRRS 3.5mm headphones that include a microphone. That said, Apple 3.5mm EarPods are described as music-only, with microphone and wired control functions not supported.
Does it need an app or drivers?
No. The adapter is designed to be plug-and-play, with no drivers or apps required.
Is the two-pack useful, or should I buy just one?
The two-pack format is convenient if you want a spare for travel, a backup, or to switch between devices without unplugging the main one repeatedly.
How long does the adapter last?
Buyer feedback suggests the adapter can be durable for normal use, but some users report cable or connection failure after a few months when used daily with pocket-heavy handling. If you depend on it for important routines, keeping a spare can help.
Can I use any 3.5mm headphones with it?
Most 3.5mm headphone setups should work for audio. If you need mic and control features, focus on TRRS headset compatibility, and note the Apple 3.5mm EarPods limitation.
