after testing various BT-speakers in this price range and something I'll have to admit that I was very, very pleasantly surprised by this pipsqueak ;-) The battery life is outstanding and with the other not comparable (making part already after 3 hours limp) The sound is truly sensational in this size and you kanns hardly believe - yes it can also Bass and remains even at higher levels very pleasant and overrides while only minimally.
