Questyle Sigma

Sounds amazing! Use USB AUDIO PLAYER PRO app for top tier sound. Simple to use with minimalist settings. Sigma has no bitrate indicator or peq. So may not be for everyone. That suits me fine as the bitrate is shown on the UAAP app & I use bit perfect mode.

Very good

Great battery life, lovely sound, Strong Bluetooth connection and plenty of power (zmf atrium)
