The headset comes in conjunction with a Nokia 3720 classic for me to use. The headset is very light, easy to use and has a very good sound - without any noise! Parties hear no difference compared to mobile phone conversations without this headset. A modification I've made - on the use of the accompanying earbuds and earloop I have omitted, instead I use a silicone-ear-Hörstöpsel (to have for little money). The unit sits firmly enough so thanks to the low weight. The no volume control on the headset is possible does not bother me - which would actually superfluous.
