Anker® Pocket Bluetooth Speaker - Ultra Portable Wireless Speaker with 12 hours of play time, NFC compatibility in com .....

Having already GNTB. 62 recessions were written, ..., I shall be brief ;-) DDD

1) Product specific:
All technical / functional / connective / battery persistent / externally valued information is correct absolutely flawless!
(With appropriate expertise + strict quality management can offer !!! as an external company also from China production absolutely quality goods)

2) The subjective sound / sound / sound-talk:
Of course, every sound / sound / sound reproducing part only times its own specific sound conditions of technology and design.
But is also a fact for which application area, including engineering, quality, and price to create the product.
And there are also physical limitations yet, (from a hat can GNTB a hare, but no moose conjure -D.) - For all the "high-end" Freaks: -D
For this now comes the buyer personally own, perhaps familiar, hearing sensitivity + velvet "Altershörfrequenzen", there are also ;-)

3) So I subjectively:
Even as a "basic package" of BT speaker sounds really good for its absolute minimum "pockets" size.
If I were still the equalizer at my BT transmitter (Tablet) adjusting a bit (Speaker responds to 120Hz low frequency) I have a great music sound, passable drums / clear concise votes / not enough shrill heights :-) - and immensely loud 4 , 5x4,5x4,5cm :-)
Of course, the site and the location of the LSPR also plays an additional role for personal vote ;-)))

Anyway, I'm very satisfied with laptops, in the living room, hall in the workplace, in your pocket where ever turn all ;-D
