If you want a high-fidelity audio pass-through with simultaneous 60W fast charging for your DJ gear on the go, choose Subynanal USB c; if you need a reliable, durable backup charging solution specifically for Raycon bone conduction headphones, choose Meliya 2-Pack. These two products serve fundamentally different roles in a mobile setup, and while one is an essential adapter for keeping your signal chain alive during long sets, the other is a practical spare part for maintaining your open-ear monitoring equipment. Trying to force either of these into the wrong use case will lead to frustration, so understanding exactly what each piece of hardware delivers is the only way to make the right call for your specific needs.
• Subynanal USB c: Its biggest strength is delivering 32-bit/384kHz audio quality while simultaneously supporting 60W Power Delivery charging through a single port; its trade-off is that it strictly does not support data transfer or QC charging protocols on all devices.
• Meliya 2-Pack: Its biggest strength is providing a safe, voltage-regulated magnetic charging experience for Raycon bone conduction headphones in a convenient 2-pack format; its trade-off is that it is not a universal adapter but is locked exclusively to Raycon compatibility.
• Who each pick is for: The Subynanal adapter is for DJs who refuse to lose battery life while playing music through wired monitors, while the Meliya cables are for owners of Raycon headphones who need a rugged, office-and-travel-ready charging spares kit.
This adapter is engineered for a very specific, high-demand scenario: bridging the gap between modern USB-C ports and traditional analog audio jacks without sacrificing power. If you are a DJ looking for the best open ear earbuds for dj setups or any scenario where you need to monitor audio while your device powers up, this dongle is designed to handle the load. It supports up to 60W PD charging, which means you can plug in a compatible wall charger and keep your phone, tablet, or laptop running at peak performance even while you are pulling audio from a mixer or a controller via the 3.5mm aux jack.
The audio fidelity here is a major selling point for anyone serious about sound quality. While many budget adapters cap out at 24-bit/96kHz, this unit handles up to 32-bit and 384kHz resolution. That extra bandwidth matters when you are trying to get a clean signal out of a digital source and into an analog input. You also get volume control capabilities directly from your connected headphones, provided they follow the CTIA or OMTP standards. This makes it incredibly useful for quick adjustments on stage or in a studio without having to fiddle with software settings on your main device.

However, you must be realistic about its limitations before buying. It does not support data transfer, meaning you cannot use this cable to move files between your phone and a computer. Furthermore, while it supports fast charging, it may not work with Quick Charge (QC) protocols on some newer phones, so you will likely need a dedicated PD wall charger to get the full 60W speed. It is also quite short at 13 cm, which is excellent for portability but might feel restrictive if you are trying to charge from a distant outlet while wearing the headphones. This product is for the user who prioritizes continuous audio playback and rapid recharging over data syncing or ultra-long cable reach.
The Meliya 2-Pack is not a general-purpose gadget; it is a targeted solution for owners of Raycon bone conduction headphones. If you rely on those specific open-ear monitors to stay aware of your surroundings while mixing or practicing, losing your ability to charge them quickly is a disaster. This product solves that by offering a replacement magnetic charging cable that is built to withstand the rigors of daily travel. The package includes two 3.3ft cables, giving you the flexibility to leave one at home, another in your car, or a third in your backpack, ensuring you never have to hunt for a charger mid-session.
Safety is a core component of this design. Inside the cable, there is a voltage regulator intended to protect your headphones from overcurrent situations. Given that bone conduction technology relies on precise vibration drivers, stable current is critical to preventing damage. The construction uses high-quality ABS and PVC materials with copper wire, which suggests a level of durability that exceeds flimsy, generic replacement cords. The magnetic connection is another key feature, allowing you to snap the charger onto your headset effortlessly without needing to align pins perfectly every time. This is particularly helpful if you are working in low-light conditions or have sweaty hands after a workout.
The trade-off here is obvious: this cable is not universal. It is strictly compatible with Raycon bone conduction models and will not function as a charger for standard wired headphones, smartphones, or other brands of wireless earbuds. Additionally, it connects via a standard USB Type-A port, so you will need a compatible power source like a PC, laptop, or standard wall adapter. For the specific demographic of people using neckband headphones for dj or fitness, this 2-pack offers peace of mind. It is a "buy it once, keep it forever" item because having a spare ensures you can always recharge your monitoring gear, no matter where you end up.

In my opinion, if you are building a professional mobile setup, the Subynanal USB c is the more critical investment. It solves the immediate problem of keeping your audio chain alive while your device drains, which is a common pain point for anyone using the best multipoint headphones for dj environments or any wired monitoring setup. The ability to pull high-resolution audio while charging at 60W is a game-changer for reliability on the go. However, I would strongly recommend pairing this with a Meliya 2-Pack if you happen to own Raycon bone conduction headphones. Having a dedicated, regulated charging cable ensures your open-ear monitors remain safe and ready for action. Ultimately, the Subynanal adapter is the primary tool for connectivity, while the Meliya cables are the essential insurance policy for your specific headphone gear.
No, this product is manufactured specifically as a replacement charger for Raycon Bone Conduction Headphones and is not listed as compatible with other brands or models.
