Hi everyone!
I've read with great attention the threads and reviews referred to the CM7s before buying them, and I was hooked by what everyone said about these.
I finally found ones used here in Argentina -they are not officially imported, so I had to wait to find someone who was selling used ones- and I have to say that I am very satisfied with these headphones, they do sound absolutelly brilliant.
However, I noticed a strange vibration when listening to deep bass sections. I'm using them with a Philips eXpanium 313 cd player -I think it's a 313, it's the red one-, listening either cds or 320kbps mp3s. For example, when listening to Bach's cello suites executed by either Pau Casals or Paul Tortelier, I can hear a strange vibration on the drivers, that does not belong to the music. Listening also to Mike Patton's Peeping Tom cd, I can also hear these strange vibration, and with pretty much any song that hass strong basses (3rd movement of Verano, by Vivaldi, another example, which by the way is brilliant, or Round About a Bass, by Pierre Michelot, Jazz in Paris).
A side note, I can note only these vibration at high volumes (>60%), or at >50% when activating the DBB (Dynamic Bass Boost, Philips calls it that way). Below 50% or 40% percent of volume, with with DBB on or off, I don't hear these vibration. 40% of volume is my usual listening volume in any circumstance -well, in my house or at work it's even lower-.
My doubt is if the previous owner did break something inside the drivers by using these at extreme high volumes, or if these just need some burn in. As he said, they were little used, as he imported these a month ago, just to find out that they would come off his ears. He showed me his very well used in-ear plugs, a pair Panasonic headphones, which would make it clear that indeed he didn't use the CM7 too much. They do not show excessive wear, and he used them with the foam pads included with the headphones.
Could it be that they're damaged, or they just need some burn in?
Thanks in advance people!
Sebastian.
