I hate to be the dissenting opinion but I just never got on with these. The fit is extremely difficult due to the large housing and short nozzle. I tried a wide variety of tips and did manage to get a seal. The sound was a bit thin anyway. After listening for about 30 minutes my wife became a little annoyed with the large amount of sound leakage. No other IEM I own leaks much if any sound. it doesn't isolate very well either. It's almost like a combo IEM/earbud really. It's possible that the sound improves greatly after break in but I never got that far. I gave up.
I do think it's great that Dsnuts found such a cheap IEM that many have found so enjoyable. In addition, I purchased the AT CKM50 from the other Dsnuts thread and I find them to be very enjoyable. Keep up the hunt, DS. Your bargain finds make the hobby more enjoyable.
