Was nearly put off by the price... but i have specific hearing needs and need good quality headset... and at last have found what i have been searching for.Pros:Extremely well madeEasy to pair to standard bluetooth device ... have paired to phone, laptop and a MP3If needed (for say an old desk top PC), comes with a bluetooth dongle (small in size - like a wireless mouse nano tx/rx'er)Comes with a well made (orange) USB cable.Can be used as a USB connected headset to laptop/desktop or desk-phone that supports USB headset...obviously charges will USB connected.Considering this head set is on the ear (as opposed to over the ear) - the Noise Cancellation is excellent (activated/deactivated via button).Pairs easily to dual devices - have used with MP3 player and Phone paired simultaneously without any issues. Phone cuts it when call active and drops back to MP3 when call dropped.Mute function via button and also if boom-mic is placed upwards.Easy to use buttons - volume +/-, mute, answer/end call, Noise Cancellation, listen-in (cuts out device audio so can hear surrounding sounds).When boom-mic is fully up, the tip can magnetically clip to the head strap - stops the boom-mic looking like an aerial :-)Battery life is excellent (have managed 15hrs so far - combined standby/music/calls) - gives an approximate battery length left when powered on (via voice through headphones)Cons:ExpensiveWhen working with a MP3 player, no button for pause or next/previousCould do with a bit more volume (but that is only if you are hard of hearing) - no issues if hearing is 'normal'Would recommend
