Very good product, audio quality.
Very clear and balanced sound, bass present (yes yes!), correct autonomy, simple and effective design, surprising for this price range. Xiaomi has done a very very good job!
What I miss a little is the impossibility to configure the speaker, such as an equalizer via an application or even the possibility of doing without voice warnings in English (powering, pairing ...). It is only for this reason that I gave it 4, not 5 stars.
I also own a UE Boom 2 speaker that I don't use anymore, the sound is so much better with this Xiaomi.
I am delighted with my purchase!
