  1. 4 out of 5

    (verified owner):

    Ready-to-use module and very easy to implement. Very low-noise if implemented correctly. Wondering if it’s possible to disable the built-in sound effects (when powered on it plays a short jingle, and when pairing too).

  2. 5 out of 5


    Good module, works as expected. The solder tabs can be a little fragile, so be careful when soldering.

  3. 4 out of 5

    Easy to use bluetooth stereo module with acceptable sound quality. Good price/performance ratio. Difficult to solder for beginners.
