Impressive on the quality of the sound it produces. Rich and vibrant for a large room in the house. Design is retro yet elegant and portable whether you entertain, doing workout, and relax with your favorite tune. Love my purchase actually bought two as I love is so much.

By using equalizer app this speaker sounds great

After using this portable speaker I found out that it's easy to connect with devices. As for the sound quality, I found out that by using equalizer you can tweak the sound to suit your liking. It comes as a default which is flat. I like to increase treble and mid range to be flat and base to be a little bit lower than the flat. Bass is by default strong and tight. For some users base might be too strong. Anyway I highly recommend using equalizer app. An excellent speaker for the money.
I would recommend this to a friend!

The sound quality and finish of this Bluetooth speaker is simply phenomenal! I’ve never seem something this compact fill a room with such big and detailed sound! HK always brings the quality and durability. I’m so impressed with the unique design. Everyone who comes over comments on how great it looks and especially how it fills the room with beautiful music! If you have the chance to get one of these just do it!
I would recommend this to a friend!
