i recently purchased the h700 .it is my 1st bluetooth .i pair it with a motorola v557 .i researched the bluetooth headsets available online .i compared features price and ease of use.i read costumer reveiws.i find this headset wonderful .it is comfortable to wear ,lite weight and small.i have never had a problem with the boom or hearing people.voices are very clear ,the volume works well.the flashing light maybe turned off if you like.no one has complained of not hearing me.matter fact no one seems to notice i am on it .i use it alot in my vehicle so i am hands free .ps no static at all.maybe it matters what phone you pair it with .the pairing and initial setup was simple worked immediately.
