Review: Still Rock Solid After 8 Years—Reliable Bluetooth Adapter for Everyday Use - I picked up the ASUS USB-BT400 Bluetooth adapter way back in 2018, and honestly, it’s still running perfectly in 2026. I’ve built and upgraded a lot of PCs, and this little adapter just keeps working. Connectivity is solid—I haven’t had issues with my headphones, headsets, mice, or controllers dropping out. Everything just pairs up and works, even when I’m swapping devices around for gaming or work. The only exception is my Fire tablet, but that’s not really the adapter’s fault. Some devices have built-in security (like locked bootloaders or pairing restrictions), so they just won’t connect to anything that’s not an approved peripheral. That’s a tablet-side thing, not a problem with the ASUS adapter. Latency has never been an issue for me, even with my high-DPI Razer Basilisk gaming mouse. No noticeable lag, even when I’m gaming or moving between devices. If you’re chasing the absolute lowest latency for competitive gaming, maybe a Bluetooth 5.0 adapter would have an edge, but for my setup, this one is honestly great. I don’t see a strong reason to upgrade when everything just works. It is a great value, it's supported by windows out of the box, it's very small too. The adapter is still going strong after years of daily use, no defects, no weird disconnects, nothing. It’s just a solid, reliable piece of hardware. For anyone needing Bluetooth on a desktop or upgrading an older PC, I definitely recommend it. Still using mine in my current rig and it hasn’t let me down. PC builder, gamer, and tech junkie approved!

(See the ASUS HelpDesk Download link in post above.) **Q: Can this transmit voice through a built in microphone from the wireless headset to talk to people if I use it for gaming?** A: Yes **Q: i have an asus laptop that doesnt have blue tooth is this what i need to use wireless headphones with my computer** A: Well, Watch out because even if you have an asus laptop this product is useless for Windows 8 or 8.1. I did call the support number and they confirmed that it wasn't happening and that Windows 8/8.1 blows. They suggested I downgrade to Windows 7. If I do downgrade to 7 it won't be to get this $15 part to work- it will be to stop the nightmarish experience of Windows 8. The number for support is 1-812-282-2787. And yes (I'm looking at you, smug sophisticated tech geeks) I should've known better, but I didn't and I hope this saves someone else a little trouble and $14.99. Dang that was a disappointing waste of time. Good luck. **Q: Does this do multiple pairing?** A: Yes, you can have multiple pairings with this device. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Still Rock Solid After 8 Years—Reliable Bluetooth Adapter for Everyday Use *by P***P on February 13, 2026* I picked up the ASUS USB-BT400 Bluetooth adapter way back in 2018, and honestly, it’s still running perfectly in 2026.

It gives great quality sound and works great. Make sure you follow the instructions and disable your old bt before plugging it in if your pc had one. When instructions are followed it works perfectly and only takes like 2 min to setup. I messed up the first try and plugged it in first and had to go back to the instructions. ## Frequently Bought Together - ASUS USB-BT400 USB Adapter w/ Bluetooth Dongle Receiver, Laptop & PC Support, Windows 10 Plug and Play /8/7/XP, Printers, Phones, Headsets, Speakers, Keyboards, Controllers,Black - TP-Link USB Bluetooth Adapter for PC, Bluetooth 5.0/5.3 Dongle Receiver, Plug and Play, Nano Design, EDR & BLE, Supports Windows 11/10/8.1/7 for Desktop, Laptop, PS5/PS4/Xbox Controller (UB500) - TP-Link USB Bluetooth Adapter for PC, Bluetooth 4.0 Dongle Receiver, Plug & Play, Nano Size, EDR & A2DP Technology, Supports Windows 11/10/8.1/8/7/XP for Desktop, Laptop, PS4/ Xbox Controllers (UB400) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ni/products/1270858-usb-bt400-usb-2-0-bluetooth-4-0-adapter](https://www.desertcart.ni/products/1270858-usb-bt400-usb-2-0-bluetooth-4-0-adapter) --- *Product available on Desertcart Nicaragua* *Store origin: NI* *Last updated: 2026-04-23*
