Good headphones white, visually pleasing, only the control panel with the keys seems a bit cheap and fragile. The keys do not convey the impression of strength or robustness. The rotary knob for high / low volume would result in a slight ribbing done well. [The manual (PDF, 02.2015) indicated key (4) for connecting is wrong key 3 (arrow forward) is the correct one. (The specified in the drawing 7 is negligible)] Treble and bass I feel as pleasant nicely balanced (but have no far-reaching "headphone experience"). Fits comfortably, well shielded from, no noise heard. Liaise with the 10m but only with the free radio link, 5m at brick wall and closed door opens grad still. Speakerphone I have not tested.
ps: have him also in use with TaoTronics® Bluetooth transmitter to a TV, work fine on each headphone output.
