Summary: Maybe it is just me but these were not stable for me and kept popping off during my workout. Sound quality not so good. Plus does not have a remote controller so cannot adjust the volume, nor take calls. It is really annoying.
Summary: Not cheap, yet still rubbish. I just want ear phones I can run in which wont fall out. These are not the ones. The fins only stabilise the buds if they fit well in your ears already. Whether the buds fit well in your ears depends on the rubber covering that covers the buds. There are two sizes given, and the smaller size worked reasonably well for the first week until one of the rubber bands came out, I don't know when but it was when the bud fell out of my ear when...
Summary: Hated these. I got these specifically for running and they fell out of my ears when I turned my head let along even took a step. I had to stop every two minutes to wedge them back in and eventually threw them away and got some old ones from eBay.
Summary: Didn't work for my ears. The hooky things rubbed and poked into my ears and levered the blue bits out of my ear canals. I then tried pulling the hooky things out, which made them a little more comfortable, but they still had an insatiable desire to pop out of my ears. I then wore a headband round my ears to try to keep them in while I was running but at best they sat on the outside of my ear canal. Complete waste of money.
Summary: Having being described as 'in-ear' headphones particularly for sports, I was shocked when, out running, these headphones fall out of my ears every 20m or so. I have tried the different sized fittings but none seem to work.
Summary: The sound is good but the earphones do not fit properly and kept falling out, I suppose it depends on your ears but I gave up on these quite expensive earphones and bought some cheap ones which fit perfectly
Summary: Great sound, as you'd expect from a brand like Sennheiser. Unfortunately, three months after purchasing the lead at the adaptor end has developed a fault which means the sound now breaks down in one ear. Probably due to the right angled nature of jack - if this was direct into your iPod/phone I'm sure that it would last longer. Disappointed, as everything else works great.
Summary: For sports, these headphones suck. The good news - is you are sitting still, not sweating, and don't move they have quite good sound. Lots of base with good, clear mid and high range. However, the minute you start to move around - you know, do athletic stuff like jogging etc - they immediately start to move out of place. Within a few minutes they will start to release from you ears and you will have to put them back in your ears.
