Avantree C81-Gaming - USB-C Bluetooth 5.3 Audio Adapter for PS5, Qualcomm Chip, aptX Adaptive & HD, Premium Sound, Works with AirPods, Bose Headphones & More

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.

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.

So far it works great. Exactly what I needed. Have an extra pair of AirPods laying around so they are now my dedicated headphones Update: the first day they worked great and were quick to set up. The next day, they connect but audio isn’t coming through. Sometimes it’ll play audio for 5 seconds and then lose it. Very frustrating

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.

He’s a little bit. Difficult to connect it but works perfect when you connected.

Ok so, I have every USB audio adapter I could find to work with my PS5. And because Sony doesn't allow "other" Bluetooth headphones, you have to be very smart on what you buy to get your non Sony headphones to work. I have a pair of Bluetooth Jabra 75's with microphone that I use for work. Because I have small ears and every manufacturer on this earth makes HUGE gaming headphones!! I wanted to use these with my PlayStation and every single USB audio adapter i tried didn't work. EXCEPT for this one! Finally, I get to use my headphones with this adapter! Also, when I turn off my PS and turn it back on, my headphones are automatically connected again. This product is a great value because it works!! Very easy to set up too! I believe it has been out of stock before, so I encourage you to buy this one and try it out instead of going through a ton of them like I did.

I bought this item for my PlayStation5 so that I could connect earbuds wirelessly. They are Bluetooth obviously as stated in the description, but when I went to connect them, they tell you to turn off every Bluetooth item you have so it connects to the one item you want to connect to. Does anybody know how many Bluetooth items they actually have because I didn’t know until I tried this and my game started to play on every other Bluetooth device that was in my house. There’s no way unless you have very little Bluetooth items and know exactly which ones they are because most people have a phone or a tablet or a laptop that has Bluetooth already in it. It’s starting to get too much of an issue to figure out how many Bluetooth items I have to run around and shut off until I could get the right one which would be the PlayStation5. Even our TVs have Bluetooth so that just is too much trouble to be able to play detective to figure out what you need to do to set it up, and hopefully it stays in the set up that you finally figure out. Don’t get me wrong, and they work for other people, and I would think since it does say PS5 on it, but I would not have had an issue, but I did. Unfortunately, I did return it and did not try to order any other one because I did not want to take a chance that this could happen again. If you want to try this, please go ahead and I hope you have better luck than I did because I think it’s a very good item and would work well with a lot of devices, however, it did not work out for me and I did not try to get in touch with technical support because it was just turning into too much work just to get earbuds to work in my PlayStation5. I did end up buying earbuds that are wired and connect directly to my controller, they were extremely reasonably priced, and I don’t know if they are popular namebrand or not, because I have not personally heard of them, but they are working perfectly now. Having wireless earbuds was just a matter of convenience, not a necessity, so it’s fine with me, but I have earbuds instead of my big bulky headphones that I will continue to use because they work well also. If you are technically knowledgeable and can connect this, then I must say I’m very proud of you even though I don’t know you. Thank you

Great adapter works amazingly on my PS4 and I'm able to connect Bluetooth headset.

Wenn es gehen würde, dann würde ich glatt noch einen Stern mehr geben :-) In meinem recht neuen Mini-PC habe ich eine etwas veraltete W-Lan/Bluetooth Kombi Karte AX200 von Intel. Hin und wieder doch mit recht schlechtem Empfang, wenn man mal das Zimmer verlässt, obwohl das nicht weit ist. Die Reichweite von diesem Gerät ist da mal einfach gleich wesentlich besser, obwohl es doch sehr klein ist. Die Installation ist kinderleicht, einstecken, Treiber wird automatisch installiert, schon fertig und loslegen bitte. Das ganze von mir unter Windows 11, Debian und Ubuntu mit Kernel größer 6.12 und 6.14 getestet. Kein Haken, kein Stottern, es funktioniert ganz einfach. Aber was wirklich bombastisch ist, der Klang ist mal gleich auch wesentlich besser, vermutlich weil die besseren Protokolle genutzt werden können und mein Edifier Bluetooth Headset NB 830 klingt gleich noch mal eine Nummer größer. Das Mikrofon wird ebenfalls unterstützt, aber das nutze ich wegen der Mono-Qualität eh nicht. Einziges Manko an der Geschichte: Der Zustand des Akku's vom Headset ist nicht mehr einsehbar, da muss dann leider anders geschaut werden ob man noch genug Saft hat.

Compré este adaptador para usar con una barra de sonido Samsung HW-T420 por bluetooth y funciona muy bien: sin lag, y con buena calidad de sonido y volumen. Lo mejor es que solo hay que emparejarlos una vez, la barra de sonido ahora enciende automáticamente cuando prendo la ps5. Muy recomendado para los que juegan en un monitor sin bocinas.

Works well with my AirPods 4. Connection is pretty stable. I can now use my AirPods for work meetings. Sound quality is ok, not the best sound quality for AirPods since it works best with the AAC codec. But overall I'm happy with my purchase.

Works awesome! I mainly got it in hopes that having a wireless connection would let me use the control panel on my speaker instead of using the ps5 sound settings and it works perfectly! No loss of sound and super quick to connect. You hardly notice it on the front of the console too. It's fantastic, highly recommend!

Great device! Works as intended, it maintains the audio quality which is good, if youre plugging the device into your ps5 but cant pair your headphones with it, try plugging the device into your phone or tablet then try pairing it with your headphones, then remove the device from your phone or tablet and then plug it into your ps5, done! Note: turn off your phones Bluetooth before plugging the device into your phone. Also, if you're using the sennheiser momentum 4, you can now adjust the audio to your liking on the sennheiser app and it'll save it's settings within the headphones and it'll work with your ps5 with the avantree c81, reason why I'm saying this is because these headphones don't save it's app settings if they're wired/plugged into your dualsense, only through bluetooth/wirelessly
