Summary: I had some sennheisers cheaper than this and they packed up nicely and had a bag for safety, these are difficult to travel with and can easily break because of this, my last pair broke at the cable end and instead of getting them covered I thought I'd go for the dynamic bass which is okay but the headphones are too cushioned and actually don't have a good hold on the ear.
Summary: I have a pair of these in White and have recently bought these in Black. The sound is good and the build quality is reasonable. The pads are beginning to flake badly on the white ones (2 years) - looks like dandruff! - however they still sound great.
Summary: I bought a pair of Sennheiser HD202 headphones a while back and have praised them for their excellent bass and very reasonable price point. I opted to get a pair of these (HD218) more recently from a popular supermarket as they were half their usual selling price and I wanted a pair that were a bit more portable than the HD202. Going by my excellent user experience with HD202 and the promise of dynamic bass on the box for these, this sealed the deal for me.
Summary: Bought them a few months ago to replace some skullcandys, great sound, comfy and brilliant value. They are still working since i use them a lot listening to music and i have so far had no problems with them whatsoever. Overall, they are a pair of really good headphones would recommend to anyone that will use them frequently.
Summary: These headphones are a bargain for the price. The sound quality is excellent, although I think the vocals and high sounds tend to stand out a bit too much for my liking. They are not the "Dynamic bass" producers that are advertised. The sound is generally flat but this satisfies my needs. My only moan is the build quality. They feel really flimsy, and it definitely wouldn't take much to break them.
Summary: These are serious enough to sound good, but small and lightwright enough to be used on the move without looking daft or feeling uncomfortable. Like another reviewer here, I had the oppotunity to test these phones against the 228 (next model up in this range) as well as other models of a similar price. These came out best in my opinion.
