XROUND's XPUMP promises to improve on virtually any set of stereo speakers, by utilizing their patented algorithms and DSP processing to offer immersive sound for everyone. Since many people do not have the room or budget for a full surround sound speaker setup, the idea here is that this tiny device can replicate much of the experience.
CCG writes - "The Sineaptic SE-1 is quite a remarkable headphone. It's an amazing first product from a new company. It does some unusual things like offering Bluetooth and 3.5mm inputs in an audiophile headphone. It offers an incredibly unique driver design at an amazingly low price. Its build quality is fine, but not spectacular, as long as you get one with no production issues."
Four years later and Sonos introduces a new portable speaker, the Move 2, bringing original innovation.
All in all, I’m a fan of the Cleer Arc II.T They’re brilliant at what they’re advertised for: being the ideal running companion.
Not sure I can find the usefulness in this device.
