I got a pair of these and to cut the story short I am disappointed. I am not an audiophile so I don't know the jargon for describing sound but I'll try to describe my impressions as best I can in everyday language.
My previous pair were Sennheiser IE4s and I really liked their sound. They had at the same time a punchy and crisp yet enveloping bass and great clarity. I could hear every vibration in string instruments and cymbals for example and lots of subtle details.
However given that the model was over 10 years old AFAIK I figured technology should have improved and went for a newer model. After going through some reviews I got the GR06s. I received them a few days ago and they are not what I had expected. Compared to the IE4s they sound muffled and lack both bass punchiness and clarity. The vibrancy of guitars I knew from before is not there. It sounds like I'm hearing them through a piece of cloth that dampens their sparkle. They also sound kind of cramped for lack of a better word and a rumbling bass overpowers the rest of the range.
I've read similar complaints in this thread. Is this really how they sound? Did I get a dud pair? Are they supposed to be adjusted through the equalizer?
If yes, can you recommend a pair closer to the sound style of the Sennheiser IE4 and under $100 (I can order from Hong Kong)? I should mention that reliability and sturdiness is a basic consideration. I use them almost daily when commuting and I don't want to risk sending them overseas for servicing.
