Review: Works perfectly with Linux! - If you’re experiencing choppy Linux audio, especially with a Realtek Bluetooth chipset, stop fighting with BlueZ and consider replacing the Bluetooth hardware entirely with a USB audio-to-Bluetooth transmitter. My PC has a Realtek Bluetooth chipset on the internal sound card, which has been a persistent source of audio problems on Linux. The most noticeable issue was music skipping in Spotify, along with intermittent stutters and lost audio frames. After far too much troubleshooting and frustration, I finally looked for a clean hardware solution. Imagine installing a completely new sound card just by plugging in a USB dongle. That’s essentially what I did. I purchased the Avantree C81-PC Bluetooth transmitter and the Avantree Audition 3 over-ear headphones, and they work perfectly. Setup was truly plug-and-play. No drivers, no configuration, no BlueZ issues, and absolutely no hassle. I just plugged in the adapter, selected it as my audio output, and music played flawlessly. I’m genuinely impressed. This isn’t an advertisement. I have no affiliation with Avantree, and before this week I had never even heard of the company. I’m simply sharing a practical solution for anyone struggling with Bluetooth audio under Linux—especially if you have a Realtek chipset and experience skipping or playback instability. Why this works Instead of relying on the internal Realtek Bluetooth radio, the Avantree adapter behaves as a USB audio device and handles Bluetooth transmission in hardware. This completely bypasses the Linux Bluetooth stack, kernel drivers, Realtek firmware, BlueZ profiles, and related audio quirks. If your audio problems come from chipset or driver instability—this approach simply eliminates them. Avantree C81-PC (Key Features) Microphone support: Your Bluetooth headset’s mic works in meetings and calls. High-definition audio: Supports aptX-Adaptive, aptX-HD, and aptX-LL (low latency). No perceptible delay: Perfectly synced audio with compatible headphones. Long range: Advertised up to 30 meters. It comes with a USB-C to USB-A adapter and is compatible with PC, Mac, and Linux. Avantree Audition 3 (Headphones) Excellent comfort and battery life aptX Adaptive / HD support for improved fidelity “Clear Voice Mode” for spoken content Wireless charging dock included Lightweight and comfortable for long use Any other headphones or earbuds that support compatible aptX codecs will also work well with the C81-PC. Bottom Line If you’re struggling with choppy audio, stuttering, or Spotify skipping under Linux and you suspect a Realtek Bluetooth chipset is involved, a hardware USB audio transmitter is a highly effective workaround. In my case, the difference was immediate and dramatic. This may be the solution you’ve been looking for.
Review: Excellent Linux performance, shows up as a USB headset - Works great! Bought this adapter because of a new gaming laptop where the bluetooth only works under Windows, not Linux. The adapter is detected as a pair of headphones, the system simply treats it as a USB audio device, and doesn't care about the bluetooth aspect. That's a bit of a black box, but the LED at least provides some guidance. Press the pairing button on the adapter and on your headphones, put them together, and they'll pair. Have tried it with a cheap-ass bluetooth headset, which gets a quality downgrade, and with my regular high-end receiver and studio monitors, which connect using aptX. Range is excellent, sound quality matches the protocol used between the devices. When unplugged, the adapter does not remember next time it's plugged in, as far as I can tell. You just have to pair again. But it does carry over across multiple reboots, including across operating systems.

## Features

- 【For PS5 Users Only】 Specifically designed for PS5 to connect Bluetooth headphones (e.g., AirPods, Bose, & more) for audio playback. For optimal voice chat experience, please use the PS5 controller microphone instead of headphone mics.
- 【Premium Sound, Low Latency】 Enjoy immersive, low-latency audio with aptX-Adaptive, aptX-HD & aptX-Low Latency. Achieve clear, dynamic audio for gaming and movies with compatible headphones (e.g., Bose QuietComfort Ultra). Note: Only aptX-Adaptive or aptX-Low Latency-enabled headphones support low-latency audio. (e.g., AirPods, Bose QC45 or QC35 do not support aptX-Adaptive and may experience audio delay.)
- 【Limited Mic Support】 Due to Bluetooth bandwidth limits, microphone input will not work with Bluetooth headphones. Please use the PS5 controller mic for clear voice communication. Manual settings required: PS5 Settings > Sound > Microphone > Input Device: Microphone on Controller.
- 【NOT FOR 2.4GHz Gaming Headsets & Other Devices】 Not compatible with Xbox, PS Portal, keyboards, mice, controllers, PS5 Pulse 3D Headset, or 2.4GHz wireless gaming headsets. Also, cannot be plugged into TVs, car systems, projectors, or printers.
- 【Easy Setup & Reliable Connection】 Plug the USB-C dongle into your PS5 and set audio output to “C81-G” once. The adapter auto-reconnects for convenience, but manual microphone setup must be performed for voice chat.

### ⭐ Does not work well with Sennheiser Momentum 4 headphones
*by D***6 on April 23, 2025*

I purchased this device over the weekend and it arrived yesterday. Today, I have spent a couple hours trying to use it with my laptop and Sennheiser Momentum 4 headphones. The headphones connect easily enough to the dongle, no problems there. The audio through various different apps (Youtube and Twitch via Chrome, Apple Music desktop app) crackles and drops out consistently. I am comfortable doing troubleshooting, so I did some googling and also went to the Avantree website, and proceeded to follow the instructions that I found, which included changing power settings, trying different ports, disabling settings in the Sennheiser headphone app, disconnecting from all nearby devices, factory defaulting the dongle and the headphones, updating firmware (which doesn't work very well, the program for that probably needs to be updated a little, it hung up or just wouldn't start almost every time I tried to run it), and reinstalling the drivers for the dongle itself. After going back and doing some searching in the reviews on here, this model seems to not work very well with the Sennheiser Momentum 4 headphones. I would not recommend it if you are trying to use them with these headphones. I emailed the Avantree support this morning through their website and have yet to hear back, hopefully they will respond, but I am planning on sending the dongle back and trying something different. May change my rating to 2 stars if the support response is helpful, but for now, I will leave it at a 1 star.
