Summary: Damn - I wish I had bought these IEMs years ago. This is just an unbelievable improvement in comparison with my UE 10 - which were breathtaking in 1996. The JH16 just explode with attack and bass slam - but are just terrific across the entire sound spectrum. It's like having a portable $50K stereo in your pocket.
Pros: Lots of detail with a wonderful transparent soundstage - with great slam on the bass.
Summary: I have to say the JH16Pro Freq-phase are outstanding. < That's the short version for those who would post TL:DNR (too long : did not read). Take advantage of the 15% off pre-Xmas sale NOW!
Associated Gear: My impressions are with my iPad 3 using lossless music and Pico Slim with TWag LOD, as well as with CCK and Pico DAC, and also right from the headphone jack of the iPad 3, iPad mini, and iPhone 5.
Pros: Impressive sound for the price, reduces my need for a $5,000 Stax SR-009
Cons: Is too much isolation a real problem? No mic on the headphone cable for iPhone.
Summary: Perfect fit first try, using a closed mouth ear impression. Funny thing is that this thing hits my ear bones. For some reason, my ear canal is not soft tissue, it's hard bone. I can't even wiggle it, it stays in place, and I may even break it with my ear canal if i press hard against it. If it were any bigger or smaller, it would not of fit. The wierd thing is that the seal stays even when I talk, or make facial contortions.
Pros: Very accurate and revealing, insane bass ability
Cons: will amplify any bad sources to the point of insanity
Summary: Nice full range frequency response IEM's, the best I have heard. I play out DJing and doing live performances, and also do lots of field recording. They are much smaller in size in comparison to my UE-18's (Ultimate Ears). They do have a slightly different sound signature compared to the UE-18's and UE-10's. The sound though isn't hugely different then the UE series IEM's. I found the sound only slightly different we are only talking very slight differences.
Pros: tight controlled bass response, smaller flaceplate over the UE IEMs
Cons: the fit wasn't quite right on both of my IEM, had to send back
