Hi everyone,

Today, I’ll show you the Avantree DG80 Bluetooth USB Audio Transmitter:

This is a Bluetooth adapter that works as a PC audio card. It transmits audio via Bluetooth using the SBC, FastStream, aptX, or aptX Low Latency codec, depending on which codecc your headphone or adapter supports. Having the aptX codec provides us with a better audio experience.

The aptX Low Latency codec allows us to watch movies and videos without any audio delay. Most Bluetooth receivers today support this codec and having a transmitter with it makes us take advantage of this.

Unboxing

The DG80 packaging is small and simple.

We can see the adapter along with its manual and documentation behind.

Using the transmitter

Using this transmitter is as simple as plugging it into a USB port and going into pairing mode.

We can see Windows detects it as Avantree DG80.

The transmitter has a bit depth and sample rate of 16bit/48khz, which is common with these adapters.

I paired it with my Fiio BTR5 and we can see it is using the aptX Low Latency codec.

Here’s a video of the pairing process of the adapter:

Audio Quality

Becuase this transmitter uses a Qualcomm chipset, the sound quality is realy great, thanks to its support of the aptX and aptX Low Latency codecs.

Signal strength

Avantree claims the adapter will work up to 30 meters or 100 feet. This may be true unless there are some obstacles in the way. In my tests with the Whooshi adapter, known to have signal issues, I was able to listen to music while I was in the same room. However, going away I could hear the audio getting cut. If you’re looking for the best signal range, the Avantree DG60 is a better choice.

Conclusion

If you still do not have a USB Bluetooth audio transmitter, the Avantree DG80 is a good start. It’s small, portable, and cheap. It also supports the aptX and aptX Low Latency codecs to provide excellent audio quality.
