If you want to add Bluetooth audio to a Windows desktop or laptop, choose Techkey Adapter; if you need a wireless controller with a built-in headphone jack for PS4 and Windows PC gaming, choose LZXWAWA Controller.
• Techkey Adapter — biggest strength: Bluetooth 5.3 with EDR, BLE and dual-mode transmission, real Plug & Play on Windows with no driver install, and a 30m open-space range.
• Techkey Adapter — biggest trade-off: It only works with Windows 11/10/8.1 and only with Bluetooth peripherals — headphones, keyboards, mice, speakers. No Mac, Linux, TV, car stereo, PS4 or Xbox.
• LZXWAWA Controller — biggest strength: A full gamepad for PS4 and Windows PC with touchpad, vibration, turbo, six-axis motion, built-in speaker and a 3.5mm headphone jack.
• LZXWAWA Controller — biggest trade-off: It's an unofficial third-party controller, so expect to pair over USB first, and it won't do anything for non-gaming Bluetooth devices.
• Pick Techkey Adapter if your goal is getting your existing wired or Bluetooth headphones working wirelessly on a Windows PC.
• Pick LZXWAWA Controller if you want one device that handles both game input and headphone audio on PC or PS4.
The Techkey Adapter is a tiny blue USB dongle that gives a desktop PC or laptop Bluetooth 5.3 with EDR. If your computer shipped without Bluetooth, or with an older, flaky radio, this is the shortest path to a stable wireless link. Techkey states the anti-interference ability is improved and that 2.4 GHz transmission loss is reduced, with a transmission rate up to 3 Mbps and a range up to 30m in open space. For headphones specifically, that's the part that matters: fewer dropouts when you walk away from the desk, and enough bandwidth for music and voice.
Setup is the real selling point. It's real Plug & Play — no driver installation — and it's backward compatible with Bluetooth 5.2/4.2/4.0/3.0/2.1, so older accessories still connect. The physical design is deliberately discreet: ultra-small, so it sits in a laptop port without blocking the adjacent USB ports. That matters on a laptop with tight spacing, or on a desktop where you'd rather not see a dongle hanging off the front panel. Weight is listed at 0.02 kg, which tells you how little it adds to a bag.
Buy it if you're on Windows 11, 10 or 8.1 and you want wireless headphones, a keyboard, a mouse or a speaker connected without fighting drivers. It can also connect multiple devices at once, and Techkey notes you can transfer files wirelessly while listening to music. Skip it if you're on Mac, Linux, Unraid, a TV, a car stereo, PS4 or Xbox — the adapter does not support those platforms at all. Also skip it if you were hoping to use it as a general-purpose audio hub for a console; that's not what it is.
The LZXWAWA Controller is a wireless gamepad built for PS4, PS4 Slim, PS4 Pro and Windows PC (Win7/8/8.1/10). It's the pick for someone who wants one device that handles both the game and the headset. The 3.5mm jack on the controller supports compatible headphones, and LZXWAWA points out you can control volume right on the controller — handy late at night when you don't want to disturb anyone in the room.
The feature list is dense for a third-party pad. There's a touchpad, vibration, six-axis motion control, a built-in speaker, and a turbo function you set yourself: hold SHARE, tap the button you want turbo on, then adjust the turbo frequency across three gears by holding SHARE and pushing the right stick up or down. The shell uses an anti-slip, ergonomic design that LZXWAWA says is meant for long sessions without fatigue. It charges over USB-C. Dimensions are 3.94 x 3.15 x 1.97 inches, and it comes with the controller, a user manual and a charging cable.
Two things to know before buying. First, LZXWAWA is upfront that this is an unofficial, third-party product — not a Sony controller. Second, the first pairing is wired: connect with the USB cable, press HOME, wait for the light bar to hold a steady color, then unplug and play wirelessly. Skip it if you need a Bluetooth dongle for a keyboard or mouse, or if you're gaming on a platform outside PS4 and Windows — this controller won't help there. Also skip it if you want a first-party pad and nothing else will do.
• Best for wireless headphones on a Windows PC → Techkey Adapter. It's the device whose entire job is the Bluetooth link.
• Best for gaming with headphone audio built in → LZXWAWA Controller. The 3.5mm jack plus on-controller volume is the whole point.
• Best for plug-and-play simplicity → Techkey Adapter. No driver install, no pairing ritual — just Windows 11/10/8.1 and go.
• Best for long-session comfort → LZXWAWA Controller. Anti-slip, ergonomic shell plus vibration and turbo for extended play.
• Best for portability → Techkey Adapter. Ultra-small, 0.02 kg, and it won't block the USB ports beside it.
• Best for platform reach → LZXWAWA Controller if you're on PS4 or PC; Techkey Adapter if you're strictly Windows and only need Bluetooth accessories.
• Best for connecting multiple accessories at once → Techkey Adapter. It supports headphones, keyboards, mice and speakers together.
• Best if you want wired-or-wireless flexibility → LZXWAWA Controller. USB-C for charging and first pairing, wireless after that.
If your actual problem is "my Windows PC has no Bluetooth and my headphones won't connect," I'd buy the Techkey Adapter. It solves that one job cleanly, works with Windows 11/10/8.1 without drivers, and its 5.3 radio with up to 30m range is exactly what wireless headphones want. I'd only reach for the LZXWAWA Controller if you're buying for PS4 or PC gaming and you want the headphone jack, turbo and motion control in the same device. Two different problems, two different answers — pick the one that matches yours, and check the current price on Amazon before you commit.
how to connect headphones to windows pc
On a PC that already has Bluetooth, open Settings, turn Bluetooth on, put your headphones in pairing mode and select them from the device list. If your desktop has no Bluetooth radio at all, a USB adapter like the Techkey Adapter adds it — Techkey states it's Plug & Play on Windows 11/10/8.1 with no driver install, then you pair the headphones the same way.
how to connect headphones to pc windows 10
The steps are the same on Windows 10: Settings → Devices → Bluetooth & other devices → Add Bluetooth or other device → Bluetooth, then pick your headphones. If the PC can't see any headphones because there's no Bluetooth hardware, the Techkey Adapter is the fix — it's backward compatible with Bluetooth 5.2/4.2/4.0/3.0/2.1, so older headsets still connect.
how can i connect my headphones to my pc
Two routes. Wirelessly, you need a Bluetooth radio — either built into the PC or added with a dongle like the Techkey Adapter. Or, if you're gaming on a PS4 or Windows PC with the LZXWAWA Controller, plug compatible headphones into its 3.5mm jack and control the volume right on the controller.

Once paired, set the headphones as your default output in Windows sound settings and you're done. For gaming, the LZXWAWA Controller's built-in 3.5mm jack routes audio through the pad itself, which is convenient when your headset cable is short or you want volume at your thumbs rather than on the desk.
