Excerpt: We’ve been told that the Sennheiser CX 280 s are the replacements for the excellent Award-winning CX 300-II s, but this MM 70i pair seems much more like them. They’re significantly more expensive than the 300s, but at least a portion of that extra cash can be put down to the three-button remote-and-mic unit, which is placed on the cable near your chin. They sound good, too. There’s impressive balance and detail, plus a weighty, but not overbearing bottom-end.
Pros: Three-button remote and mic, weighty bass and decent detail, clean and clear sound
