The Sennheiser MM70 are very good quaility ear buds. OnceI had run them in (took about 15 - 20 hours) the depth of sound is comparable to earphones at twice the price.
The remote is a very good addition, however the control panal is not very ergonomic and I find that it can catch on buttons. The other minor criticism is that these are the asymmetric type earphones (which I prefer) but the "short" cable which has the control panel and mic is too long (about 30cm) and I find that it loops round too much.
Aside from these minor grumbles they are very good earphones with excellent sound quaility - which is the most important thing.
I purchased the cable so I could charge my iphone via a docking station, unfortunatly the cable does not appear to be able change devices (other cables worked fine). In addition the cable lenght was closer to 80cm than 1.8M as advertised. A pointless purchase.
