- Inateck Portable Bluetooth Stereo
=> My purchase decision, by far the best sound!
- Raikko EVOLUTION Bluetooth Stereo
=> Sounds a bit flat but overall still OK! (Large battery; including USB for external devices.)
- ARCTIC S113 BT
=> Sounds the least of all 4! (For the cheap price but really not ok!)
- Logitech UE Mobile Boombox
=> Sound is more deep and dull, not really rich detail! (Great robust housing!)
No one was really bad, but I have decided in the direct sound comparison for Inateck.
Otherwise, I have tested or compared, I decided purely for the best sound nothing!
