Hahaha  no, it happens when it's silent too, it's my resting pulse. Shows you how good the isolation is! I'm still trying to adjust to the EPH-100, from the bass-heavy and warm ATH-CKS.  Thank god I didn't end up going with the GR07, that would have sounded bright as heck to me

Awesome album, thanks for introducing me to it! Guys I can hear my heartbeat really clearly when I listen with the EPH-100, is there anything I can do?   lol

Hmm thanks for the advice about the fit.  I'll keep experimenting! I think most of my complaints are due to my coming from the ATH-CKS50, which is known to be quite bass-heavy.  I'll give these a few more days of burn-in and listening and see what happens.

for example, http://www.youtube.com/watch?v=bAtGfJ5ZoDM http://www.youtube.com/watch?v=wOLiEu7275E Skrillex - Kyoto ft. Sirah Klaypex - Lights  (I listened to the FLAC ones of these two)   Especially in the first one, they sound quite boosted, bright, and unrealistic to me. This...

Well, well...

Take a look at the Yamaha EPH-100 thread at http://www.head-fi.org/t/577712/yamaha-eph-100 while you're at it. Lots of good word so far. mine are arriving tomorrow so I can't really judge them yet...

Weellllll... I just pulled the trigger on the EPH-100.  I figured that the GR07 couldn't be that much better than the EPH-100 for $40 more.  The EPH-100 is going for 139 on amazon now, $10 cheaper than before. They should be here on Friday! I should have checked before ordering, but has anyone...

apologies for my ignorance of audiophile vocabulary, but would you say that the EPH-100 isn't as flat or neutral as the GR07?  While not ideal, I will also be using them for recording as well

So how would you say they compare with the GR07?  I'm trying to decide between the two

  Hi all, I'm looking to move up to new IEMs.  I currently have an ATH-CKS50 that I bought in Japan. From reading threads here so far, it seems that two of the top choices for this price are the GR07 and Yamaha EPH-100.  How do these compare in your opinion, and are there others that I...
