Summary: I've now had 4 pairs of theses headphones. They sound great but sadly the build quality is terrible. The first pair broke within 2 days, the 2nd a week, The third a few months and we'll see about this pair. Tesco have promptly collected a ad returned all the replacements but now I'm having to deal with Sennheiser which is an awful experience and i can't get my money back from them :-(
Summary: I was just about to buy my third set of these after the first two sets both broke after 6-18 months of use. They do have excellent sound quality but after seeing all these reviews I am not the only one to have problems with these. I think I will look for another model/brand now. Avoid.
Summary: The quality of the specific headset is very poor compared to my previous headphones by the same company; it is way below my expectations. The sound range sounds much more limited than my cx980 headphones and the quality of construction seems to be very poor! I was very surprised as I got these headsets as a replacement to another NM50 which after 4 months of use died on me...
Summary: Unfortunately, whilst these headphones look just the ticket, they are fundamentally flawed and don't work properly with either the iPhone or the MacBook Pro!!! I have had a replacement iPhone so am pretty confident that it's not the jack itself. The issue - only sound from the right earbud is normally available. It is possible, by rotating the plug in the jack or loading it to get the other one going but usually this only works for a few seconds.
Summary: On to my 2nd pair. Sound is so so. Biggest problem though is that the connector wires are fragile as hell. If you plan on using these with your iphone in a pocket forget it. After a few months you will have sound cutting out in one ear, or loss of sound channels to both ears (e.g. vocals cut out, but you still hear the background music muffled). Strongly advise avoiding these.
Summary: Too bad, I really liked these! I was just about to buy them again (for £20 that would be a real bargain, I think). They're very comfortable and the sound quality (ear phones and mic) is great. But I've had the same problem as others after barely 2 months of normal use. The cable seems to be broken just above the jack.
Summary: I got these as a Christmas present. Had previously owned some headphones for my PC by Sennheiser that lasted years. Down to business. Sound quality is not great, the rubber around the speakers has no grip whatsoever, the button on the stalk is recessed and therefore almost impossible to press if you have large fingers and now they have broken after less than two months.I used them with my 3GS for my commute into London and sitting at my desk at work.
Summary: I've had 2 pairs of these now and while the sound quality and the microphone are great they don't last long at all. Both pairs went within 3 months of use at the exact same point, just above the jack. They both lost all vocals on the music and became very "tinny". If I move the wire around I can get the sound to come back but it has to be held in place, basically the wiring underneath has frayed and became loose. I won't be buying another pair.
