(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. ## 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.hr/products/1270858-asus-usb-bt400-usb-2-0-bluetooth-4-0-adapter](https://www.desertcart.hr/products/1270858-asus-usb-bt400-usb-2-0-bluetooth-4-0-adapter) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-06-22*
