Purchased the BT125 a few ago. Paired with my Nokia phone flawlessly and started working right after I charged it. However the fit is not as comfortable as I would like. Call quality is good as long as phone is within 10 feet or so. Beyond that, it start crackling (sometimes even when it is in my pants pocket). Also not very good if you are in noisy conditions (driving with windows rolled down, etc).But overall for the price (around 30$ with shipping), not a bad headset.
