If you look at my profile, you'll see that I've got mainly mid-fi sources, so this was my first chance to have an extended listen to higher end gear. I did most of my critical listening with three headphones, modified Grado SR80s, Beyerdynamic DT880/250s, and Grado HF-2. I did try them with customs one evening, with unsatisfactory results I'll go into below. I listened to them as a combo, only, usb out with foobar2000. I don't have a set list of tracks that I use to test gear. Generally I'll come up with a list of things that I'm currently listening...

I was one of the ten people chosen to review these iems. You can read my full review here. These are really great phones for vocal music. They're not so great for hip-hop or anything that needs a deep, tight, punchy bass. They're light and easy to wear. I don't love the design, preferring over-the ear phones in the main, but that's a minor quibble. If you're interested in this sound signature, this would be a good phone to try out. I'm not sure what the MSRP will be, but if they're priced like the RE0s (<$100), it's a good investment.

I wanted to upgrade my computer sound card in preparation for higher impedance phones and eventually a desktop amp. This more than does the trick and improved onboard sound more than I'd expected.   The con about it needing a good power source isn't an argument against it. It turned out that my computer (Vostro 420, 2009) didn't have an extra power connection for the card so I ended up upgrading my power source as well.  

I jumped on these when Amazon had them on sale.  I had only been on Head-Fi for a month and was looking around to expand my listening horizons. I've had them for nearly a month, but hadn't reviewed them because I wanted to get past the new toy period and listen to them over an extended bit of time and with lots of different material.   Fit was an issue initially. They're huge and I have smallish flush ears. There was a lot of rubbing on the right pinna until I did the flip thing and put on Comply TX-500 tips.  The best fit has come with medium...

Rockbox it and you've got great sound in a tiny package. Give it to an amp and it's better yet, but not so portable.   After looking around at some other reviews, here are a few more details.  First off, I should say that I'm a music lover, not an audiophile (yet).  Although I can detect some differences -  between amped and unamped sources, between the different headphones and IEMs I own for example - I don't yet have the depth of experience or language to give an extremely detailed review of this little player.   Did I say it was little...

I joined head-fi, looking around for replacement IEMs, and found people talking about headphone amps.  After some research, I decided on the PA2V2s and couldn't have made a better choice for a beginner's amp.   I've tried this amp with an iPod nano, an iRiver iH-140 (rockboxed), a Cowon iAudio 9, and a Clip+ (rockboxed), with ER6s, ER-4Ps, and Grado SR80s. The amp warms the sound of the etys, but not to the extent that it distorts their characteristic sound.  I noticed a larger soundstage on the Grados.   But the real treat, with all sources...
