SIXSIM wins the samsung headphones case search for sleeping: its adapter lets you use wired headphones while charging a compatible phone.
QianLink is the runner-up if you want a longer, braided audio cable for a bedside setup instead.
• SIXSIM USB-C Headphone Adapter — best for listening while charging; pick this if you want a 3.5mm jack and PD-compatible charging in one adapter.
• SIXSIM USB C — best for keeping a spare adapter handy; pick this if you want two 2-in-1 adapters that support up to 60W PD charging.
• QianLink USB C — best for a bedside or car-stereo connection; pick this if a 3.3-foot braided audio cable suits your setup.
• JXMOX USB Type C — best for compact, wired headphone use; pick this if you want a short adapter with microphone and wire-control support.
This is my pick for the main use case: listening to wired headphones at bedtime without giving up the phone’s USB-C port for charging. The adapter splits that port into a 3.5mm audio jack and a USB-C port for PD-compatible charging. That can be useful when you listen as you settle in and want the phone connected to power at the same time.
The audio side supports DAC formats up to 16-bit/192 kHz or 24-bit/96 kHz, with ADC support up to 16-bit/48 kHz. It also lists compatibility with CTIA and OMTP headphone standards. Those details give you a clearer picture of the audio connections it supports, though they do not guarantee that every phone, headphone, or app will behave identically. Check that your particular Samsung model is compatible before choosing it.
The adapter supports up to 60W PD charging. That is a maximum supported charging specification, not a promise that every phone will charge at that rate; the product information recommends a PD wall charger and notes that QC may not work with some newer phones. The adapter also does not support data transfer, so it cannot serve as a general USB-C connection for moving files.
The package contains two adapters, which gives you a spare for another listening spot or a travel bag. In my opinion, that combination of pass-through charging, a standard headphone jack, and a two-piece pack makes this the most practical choice here for bedtime listening. Its main compromise is that it adds an adapter between the phone and headphones, and it is not useful for data transfer.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
This SIXSIM option has the same basic idea: one USB-C connection becomes a 3.5mm audio jack plus a PD-compatible USB-C charging port. It is aimed at someone who wants to use wired headphones and keep a charging connection available, rather than someone looking for a wireless headset or a storage case.
Its listed audio support includes DAC formats up to 16-bit/192 kHz or 24-bit/96 kHz and ADC up to 16-bit/48 kHz. It also supports CTIA and OMTP. In everyday terms, those specifications indicate support for common wired-headphone configurations and audio conversion, but they do not establish compatibility with every device combination. Confirm the listing’s compatibility against your exact Samsung phone.
Like the other SIXSIM adapter, this one supports up to 60W PD charging and comes as a two-pack. That may appeal if you want one adapter near the bed and another in a bag. For charging, the product information suggests using a PD wall charger and warns that QC may not be supported on some newer phones. It does not support data transfer.
The distinction between the two SIXSIM picks is not a major change in function; both offer the same central charging-and-audio layout and similar stated audio specifications. I would choose this version if you prefer its listed device compatibility or want a spare pair of adapters. The trade-off is the same: it solves the port-sharing problem, but it does not provide a cable extension or wireless listening.
QianLink takes a different approach. Instead of adding a charging port, it is a USB-C-to-3.5mm audio cable, supplied as a two-pack. Each cable is 3.3 feet long and has a nylon-braided exterior. That extra reach can be useful if your phone rests on a nightstand while your wired headphones are in use, or if you need to connect a phone to a car stereo or speaker with a 3.5mm input.
The cable includes a DAC chip for converting digital audio to analog output, and it is described as plug-and-play, with no separate software or driver required. Its compatibility list includes several Samsung Galaxy S and Note models, as well as certain other USB-C devices. Because model support can vary, check your specific phone before buying rather than assuming that any USB-C port will work with it.
I would choose QianLink when length matters more than charging pass-through. Its 3.3-foot cable and braided construction make it a sensible fit for a bedside or car setup where the phone and listening position are separated. For sleeping, though, the extra cable length can also mean more cord to manage; it is a straightforward wired solution, not a purpose-designed sleep headset.
JXMOX USB Type C
JXMOX is a compact USB-C-to-3.5mm adapter for wired headphones. The short adapter is described as about 11 cm long, with an ABS shell and nylon-braided wire. It is intended for plug-and-play audio without a separate driver, and the product information lists compatibility with a range of Samsung Galaxy phones and other USB-C devices.
Its DAC supports audio sampling up to 16-bit/48 kHz. The adapter also supports headset wire controls, including functions such as microphone use, volume adjustment, and play or pause controls. That makes it a more relevant option than the QianLink cable for someone who wants to use a wired headset’s controls, although the exact behavior still depends on the phone and headset combination.
The big trade-off is that JXMOX does not provide a second USB-C port for charging. If your phone needs to stay plugged in while you listen, the two SIXSIM adapters are better suited to that job. JXMOX is also much shorter than QianLink, so it will not offer the same reach between a phone and a nightstand.
In my opinion, this is a good fit for someone who wants a small adapter to leave attached to a pair of wired headphones or carry in a pocket. The listed two-count package can also leave you with a spare. For a sleeping setup, it may work with in-ear earbuds for sleeping if you already have comfortable wired earbuds, but this adapter itself does not make earbuds more comfortable or safer for overnight wear.
How We Picked
We compared the published specifications and features for audio, charging, cable design, and listed compatibility.
The order reflects our independent editorial opinion about the products’ usefulness for the stated listening needs.
The two SIXSIM adapters include a 3.5mm audio jack and a PD-compatible USB-C charging port. QianLink and JXMOX are audio adapters without charging pass-through.
JXMOX specifically lists microphone and wire-control support. The SIXSIM adapters list CTIA and OMTP compatibility; QianLink’s product information says it does not support microphone recording.
No. These products connect a USB-C device to wired headphones or another 3.5mm audio input. They do not provide wireless listening.
Check that your exact phone model appears in the product’s compatibility information, then consider whether you need charging while listening, headset controls, or extra cable length. These products solve different connection needs, so the most suitable option depends on the setup you want.
My final recommendation for sleeping is the SIXSIM USB-C Headphone Adapter: its audio connection and PD charging port let compatible phones handle wired listening and charging at once.
