• Zosvoses QC35, biggest strength: a USB-A to Micro-USB cable built specifically for Bose QuietComfort models, rated for up to 3A of current so the headset charges quickly instead of trickling.
• Zosvoses QC35, biggest trade-off: it is one short 25 cm cable with a hard-wired Micro-USB plug, so it only helps if your headphones use that connector and you have a USB-A port free.
• Weleecty Dual USB-C Headphone, biggest strength: one USB-C port becomes two, so you can run 60W PD fast charging and a wired headphone feed at the same time on phones, tablets and laptops.
• Weleecty Dual USB-C Headphone, biggest trade-off: it is an adapter, not a cable, and it does nothing for headphones that charge over Micro-USB.
• Pick Zosvoses QC35 if you own Bose QC20, QC25, QC35, QC35 II, QC30 or SoundLink Around Ear headphones and want a compact spare charger.
• Pick Weleecty Dual USB-C Headphone if you are on a USB-C phone or laptop and refuse to choose between charging and listening.
This is a single-purpose accessory, and that is the point. The Zosvoses QC35 is a 25 cm USB-A to Micro-USB charging cable aimed squarely at Bose's QuietComfort line: QC20, QC20i, QC25, QC35, QC35 II, QuietControl 30 and SoundLink Around Ear Wireless headphones. If you own any of those, you already know the annoyance of a lost or frayed charging cord, and this is the direct replacement.
The fast-charge side matters more than people expect. The copper core is rated for a maximum 3A current and works with devices drawing anywhere from 500mA to 3000mA, and the cable supports 5V/3.0A charging over USB-A. In practice that means a proper top-up rather than the slow drip you get from a random spare cable pulled out of a drawer. The build is thickened PVC with a claimed 10,000-plus bend cycle rating, plus built-in protection against over-voltage, over-charging and overheating, so it is designed to live in a pocket or a bag without falling apart.
The 9.8-inch length is the detail that decides it for a lot of people. It is too short to stretch across a desk, but exactly right for a power bank in a jacket pocket, a car USB port, or a wall charger on a nightstand. Who should skip it? Anyone whose headphones charge over USB-C, anyone who needs a long cable to reach an outlet across the room, and anyone hoping to charge a phone from it — the Micro-USB end only fits Micro-USB devices.
The Weleecty adapter solves a different, more modern problem: phones and tablets that dropped the headphone jack. It is a 1-in-2-out USB-C splitter that turns a single Type-C port into a charging port plus an audio port, so you can plug in wired headphones and keep the device on a charger at the same time. No juggling, no pausing your game or call to swap plugs.
The headline spec is 60W PD fast charging at 20V/3A. That is enough headroom for USB-C laptops, iPads and Galaxy phones, not just earbuds. Audio runs through a Hi-Res decoding chip rated at 32-bit/384kHz, and the adapter supports volume control for calls and music, which makes it practical for hands-free meetings and video conferences as well as gaming. Compatibility covers USB-C laptops, tablets and phones, including iPhone 15 and 16, Galaxy S23 and S22, Pixel and Huawei devices. Weleecty also backs it with a 2-year warranty description.
It is worth being clear about what it is not. There is no plug of its own — it draws power from whatever you connect it to — and it will not charge a Bose QC35 or any other Micro-USB headphone, because the connector standard is different. It is also not a replacement for a dedicated charging cable; it is the thing you keep in a laptop bag so a single USB-C port stops being a bottleneck. The trade-off is straightforward: you gain simultaneous charge-and-listen, and you give up the simplicity of one plain cable.
• Best for Bose QuietComfort owners → Zosvoses QC35. It lists the exact QC20, QC20i, QC25, QC35, QC35 II, QC30 and SoundLink Around Ear models by name.
• Best for charging and listening simultaneously → Weleecty Dual USB-C Headphone. One USB-C port becomes two, with audio on one side and power on the other.
• Best for higher wattage charging → Weleecty Dual USB-C Headphone. 60W PD at 20V/3A versus the Zosvoses cable's 5V/3.0A over USB-A.
• Best for travel and pocket carry → Zosvoses QC35. At 5 g and 9.8 inches it disappears into a pocket, and it needs nothing but a USB-A port.
• Best for cable durability against daily abuse → Zosvoses QC35. Thickened PVC, advanced welding and a 10,000-plus bend rating, with over-voltage, over-charging and overheating protection built in.
• Best for wired audio quality on a USB-C device → Weleecty Dual USB-C Headphone. The 32-bit/384kHz decoding chip is aimed at listeners who care about the source.
• Best for calls and video conferences → Weleecty Dual USB-C Headphone. Volume control plus a stable, no-overheating output suits long meetings.
• Best for a modern phone with no headphone jack → Weleecty Dual USB-C Headphone. It is designed around iPhone 15/16, Galaxy S23/S22, Pixel and Huawei hardware.
In my opinion, these two barely compete — they fix different problems, and the right answer depends entirely on the connector on your headphones. If you own Bose QuietComfort gear, I would buy the Zosvoses QC35: it is cheap insurance against a dead headset, it charges at up to 3A, and the 9.8-inch length is ideal for a power bank or car port. If your headphones plug into USB-C and your phone has no headphone jack, I would buy the Weleecty Dual USB-C Headphone instead, because 60W PD passthrough plus a Hi-Res audio path is the more useful tool in that setup. Check the current price on Amazon before you commit — but match the connector first, because the wrong one is useless.
FAQ
How to fast charge bose headphones
How to charge headphones faster
Two things matter: the cable's current rating and the charger behind it. A cable limited to a trickle will hold you back no matter what it is plugged into. The Zosvoses QC35 handles 500mA to 3000mA devices at up to 3A, which covers the full range Micro-USB headphones need, while the Weleecty adapter pushes 60W PD at 20V/3A to USB-C devices.
How to charge headphones
Match the plug to the port. Micro-USB headphones like the Bose QC20, QC25, QC35, QC35 II and QC30 need the Zosvoses QC35 cable plugged into a USB-A charger, computer or power bank. USB-C headphones and phones work with the Weleecty Dual USB-C Headphone, which passes power through one port and audio through the other.
Is fast charging bad for headphones
Not when the cable is built for it. The Zosvoses QC35 includes multiple protection systems against over-voltage, over-charging and overheating, and the Weleecty adapter is described as delivering stable output with no overheating. Fast charging is regulated by the device as well, so a properly certified cable does not put your headphones at risk.
