Sony Ericsson HBH-IS800 Stereo Bluetooth Headset (Black)

Pros: Extremely small and lightweight
Clear microphone - callers don't even know I'm on a headset
Battery life lasts around 5 hours

Cons: Hasn't affected me so far but a volume control would be nice
I can live without it but a track skip would be nice

Summary: Almost didn't buy these because of the negative reviews about not having a volume control but I also read one where someone said he was glad he didn't listen to the reviews and was happy. I took a chance because I use mine at the gym and the cord is constantly pulling on one of the earplugs and has become a nuisance. I did not want to wear the big hearing aid style headsets or one with a hard plastic connector due to laying on benches etc. These are a godsend! The volume is totally acceptable, not blaring at all. They fit my ears just fine after I put the biggest rubber pieces on and the battery lasted 5 hours the first time. I totally recommend these over any other for their svelt design and awesome clarity. The built in microphone allows me to take calls at the gym without switching anythign and I can't wait to use them in the car on trips. This headset is a must have, only sorry I didn't buy them sooner.
