The sound quality is really great, especially for a device of this size and price. The volume gets loud enough to be "too loud".
The only problem I have with this product is the Owner's Manual. Given the quality of the device I expected better quality from the manual. As you'll hear in the video, the manual was clearly not written by someone who speaks English natively, nor proofread by one. Worse things could happen than a little ambiguity in a manual for a product as intuitive as this. Because it looks to pair with previously paired devices AND looks for new devices when powered on, setup is a snap.
The small hole to the left of the charging port is the LED indicator. It is small and unobtrusive though it is a little tricky to see while charging.
Overall this is a fantastic little speaker that looks nice on a desk and provides a crisp, clear sound.
I got mine from Amazon
