I run daily. I have had over a dozen sets of headphones for use whilst running over the last 20 years. Some have been lost, most have been broken, all but one were wired. The Backbeats' were my second set of bluetooth headphones. They are by far the best 'phones I've had, in particular for ease of use (and I wear glasses), although the volume limiter can be frustrating when being used on public transport - it doesn't need to go up to 11 but 6 would have been good. However, the major criticism is the after-sales. In brief, there isn't any. The ear buds frequently detach themselves. When I finally lost one I contacted Altec Lansing with a simple request for replacements. No-one (absolutely no-one) stocks them in the UK. Finally got replacements from the US.
