I'm looking for some information or experience from other IE 800 owners on a problem I have with my set. A lot of music I'm listening too, mostly rock of various 'strengths' from U2 to Pantera, has a fuzzy distortion over the top of a lot of it (separate to expected instrumentation distortion like guitar effects). It's a static style white noise that shows itself especially over the top of the more complex or noisy parts or tracks. I think the noise sits in the upper mid range/lower treble. I was originally amazed by them, but once I settled into using them this problem because apparent and now it's just grating when it happens.
As I can't exactly describe sound in words the best way I can describe it is that it sits apart from the track itself, which in all fairness always sounds amazing through them if not for this problem, but it sits separate to the track. As an analogy its like someone is rustling a packet a few rows behind you in a cinema, or when a really clear radio station still has some static coming through.
To make sure the source wasn't the issue (either player or track) I tried some of the more obvious tracks with different players, files and headphones of varying quality and in all cases I could always hear it on the IE 800s and never on any other headphones. I tried the following:
- 320K MP3 and Level 8 FLAC from a Cowon X7 and a Cowon Z2 through the headphone port to IE800s, Cowons own earphones and apple earbuds. Problems can only be heard on IE800s
- Original CDs fed through from Marantz UD7007 to my AV unit (Pioneer SC-LX56) using the front headphone socket for HD800, HD650 and IE800 on a 3.5mm adaptor. Problems can be heard on IE800s and nothing else.
- Original CD fed through from Marantz UD7007 to my HDVD 800 amp using the front headphone socket for HD800, HD650 and IE800 on a 3.5mm adaptor. Problems can be heard only on IE800s.
- PC sound card (Rampage 4 Extreme on board sound chip) to Sennheiser PC363D and IE800s
After that level of testing on most the equipment I own the only consistent factor is the IE 800s themselves.
I sent them back to Sennheiser who returned them as not faulty (I do not know what testing regime they have for this type of fault). At least half of the tracks from my 700 odd album collections I have listened to have these distortions pop up at least once, from just a momentary fuzz for a split second, to most of the track.
Has anyone else experienced this? I don't have a second pair to do a like for like test with but it's so obvious now I'm accustomed to them that either this unit is faulty or the IE 800s are problematic in general.
A great example for this issue is the track Bad Habit by The Offspring on their Smash Album. It's most noticeable after 1min 25seconds.
Thanks for any help anyone can give.
