Also this headset from Jabra convinced by nice, clean design. The sound has not fully convinced me. The bass can be very pronounced for my taste. Clear mids and highs. Runs slightly bigger than Jabra Revo. For my big head still too small. For me it is incomprehensible that the Jabra designers include head circumference too little in this clear Scandinavian design. A size problem I've never had in other products. I realize that this might affect only a small portion of potential customers.
