I can still enjoy music at all rooms with closed door up stair while Galaxy S4 as the player located at center ground floor. It has the widest Bluetooth coverage among all my Bluetooth devices so far. As usual, all my Windows, Android and iOS devices can pair with it easily. By the way, my U171 is a base model and does not have NFC feature. However, Gsou Technology does have U171 with NFC feature support as optional. Same apply to TF (microSD built-in MP3 player) and FM radio. For devices without Bluetooth, 3.5mm AUX line-in port is there for you.

Any complaints? The zinc metal part is fingerprint magnet. Luckily, it only affects the look but not the sound and can be cleaned easily.
