Excerpt: So far i had great experience with Sennheiser. My other headphones broke and I contacted the Sennheiser customer support, received new headphones in a week or so. MM70s were recommended by B&H sales representative. It was a present for my son and he loves them so far. The sound is very clear and the bass is nice. He's using them with his Samsung Galaxy S3 and now S5. Not a single complaint.
Pros: Comfortable, Compact, Durable, Good Bass, Good Value, Great Sound, Lightweight, Stylish
Excerpt: I did a ton of research in this price range and settled on these because of other reviews on the quality of sound...and they sound amazing. Great bass that doesn't bury the highs or vocals and the multitude of earbuds do a great job of blocking outside sounds once you find the right size for you. The only things I don't like are the cable not being flat (it's pretty thin) so it tangles easily and the connection of the cable to the earbud seem similar to low end buds.
Pros: Comfortable, Good Bass, Great Sound, Lightweight
Summary: The cable is too short for most things, which is strange given that the other version is longer. The volume control is pointless, I have had a cheaper version which actually can alter the volume of the device. Sound quality and fit are fine.
Summary: Serious ear bins for House Music heads, especially Deep House. Excellent sound, was blown away when I first used them Undistorted Bass drives very well, even when cranked right up, without losing mids, highs and vocals. They also come with a mic, so get these if you're serious about your music and need to walk around looking like you're talking to yourself.
Summary: Good sound review. I've never had a problem with it. However the length of the headphones are an issue. I'm 6' and have to frequently have my phone on my torso instead of my legs. I had previously had the mm30i and they worked perfectly. Also the volume control is seperate to the devices control. Often the volume becomes lower without me knowing as it's quite easy for the headphones when being dragged through to change its volume.
Summary: I find the sound quality of these to be excellent for the sort of music I listen to, (60s (Beatles, Stones etc.) and classical). typical of Sod's Law I have not yet received a phone call whilst I have been using them but the volume control is very useful.
