Before You Buy
Before you buy the Avantree C81 USB-C Bluetooth audio adapter for PS5, there are a few things to keep in mind.
First, it's not compatible with Sony PULSE 3D or other non-Bluetooth headphones.
Also, this device transmits audio only, so you can't use it with mice, keyboards, controllers, or any other devices that don't rely on audio signals.
If you want to use it with your PC or other devices, consider the C81-PC for the best results.

PS5 Bluetooth Adapter Requirement
The PS5 requires a Bluetooth adapter because Sony restricts native Bluetooth to controllers only, blocking third-party headphones.
To use a Bluetooth adapter with your PS5, you'll need to look for one that can act as an external transmitter, converting USB audio to Bluetooth 5.0/5.2 signals.
Some adapters, like Avantree's C81, support bidirectional audio (A2DP+ HSP/HFP profiles), which is essential for voice chat.
A good adapter should have USB-C compatibility and low latency, ideally under 40ms, to minimize disruptions in sync.
Avantree's C81, for instance, reduces lag to 32ms, making it suitable for rhythm games.
However, some budget adapters may introduce 100–200ms delays, which can be a major issue for gamers.
Premium models like Avantree's support simultaneous pairing with two devices, ideal for co-op gaming and seamless multiplayer experiences.
It's worth noting that some adapters may require firmware updates via PC to support newer codecs.

Troubleshooting and Performance
Interference from devices like Wi-Fi and microwaves on the 2.4GHz frequency can cause connection drops.
Switching to the 5GHz Wi-Fi network or changing adapter channels can help resolve this issue.
Persistent connection dropouts often occur in crowded RF environments.
Using a USB-C to USB-A converter can help place the adapter away from the PS5's EMI-heavy internals, similar to relocating a sensitive component to avoid heat zones.
Updating the adapter firmware via the manufacturer's app, such as Avantree's Fleet software, can resolve up to 85% of dropout reports.
Checking headphone battery levels and power-saving modes can also help resolve intermittent sound loss.

Updating adapter firmware via manufacturer apps can also resolve connection dropouts. For example, Avantree's Fleet software resolves 85% of dropout reports.
If you're experiencing intermittent sound loss, it's possible that your headphones are running low on battery. Be sure to check the battery levels and adjust power-saving modes as needed.
Latency and Codecs in Gaming Audio
Latency under 50ms is imperceptible to most users, but it's still essential to optimize for the best gaming experience.
Codecs like aptX-LL and LC3 significantly outperform standard SBC in terms of latency.
A 100ms delay can cause noticeable lipsync issues, which is why advanced codecs are crucial for gaming audio.
Avantree adapters prioritize protocols like aptX-LL and LC3 for real-time audio, achieving impressive results like 38ms latency in Rainbow Six Siege.
Using the right codec can make a huge difference, and manually selecting the lowest-latency option via physical switches or companion apps is a great idea.
Keep in mind that walls or interference can spike latency, so keep the adapter within 10 meters for the best results.
