## Description

High Quality JVC HEADPHONES, INNER-EAR, BLUE

Review: These are my favorite headphones so far! - I must admit, I am not an audiophile. I do keep buying headphones, however, as I like to listen to music all day at work. I like headphones that keep me from having to listen to my neighbors in their cubes. I listen to all kinds of music, including: classical (piano and symphonic), Electric Light Orchesta, Pink Floyd, Beck, Gorillaz, Beastie Boys, Tori Amos, Peter Gabriel, Elvis Costello, and lots more - so heavy on the bass to music with more subtle details required. Active noise cancellation does a good job shutting up the eight core computer that sounds like a 777 taking off, but can sometimes make the neighbors LOUDER, so I would rather have isolation or inactive methods. Earbuds suit me best because I'm rather particular about not having a line across my head from my headphones. My favorite headphones have been a pair of Shure, but those are annoying because the wires wrap around the backs of your ears, and the wires are too stiff. Annoying when I turn my head. They sound decent though. I ran out of the wax screens though, and $10 for a new set?! I have Sennheisers they sound OK, but not terrific. They get the job done, and have been my most heavily used pair. There have been many others. Mostly they are in a landfill somewhere outside Denver. Then I came across these. I left them burning in for about 3 days straight back at home, then I brought them into work. I switched back and forth many times between these and the Sennheisers. Absolutely no comparison. What really got me is that the dynamic range on these was so much larger that the stereo separation seemed so much larger. Those Sennheisers are now in the trash as well. Bass response - just right. Not too exaggerated. Not weak. Perfect to my ears. Higher details - present. I hear subtle details in complex music (high bitrate mp3 very important) that can be difficult to find in low quality headphones. Overall balance - very pleasing. Very natural. Perfect, IMHO. I'm finding that these also do sound better than the Shure headphones that I paid WAY more for. I'm VERY impressed and am going to recommend these for everyone I know. Do there really contain carbon nanotubes? I'm surprised that they were able to use that technology in something so low priced. I'm skeptical that they're really being used to a significant extent in this product, especially at this price point. But whatever JVC did with making this product, they did it right. This is an ABSOLUTE MUST BUY.
Review: Excellent Quality, would purchase again - I chose these as a replacement for the standard Apple headphones, which came with an iPhone 4S. Having used them for a few months, I am quite pleased with both the sound quality and the construction quality of these headphones; its definitely a large upgrade from the Apple phones, while being very affordable. Certainly much better than similarly priced pairs, such as Skullcandy models. The cord clip is really nice for keeping the cord from getting itself around drawer pulls and the like. They also stay in my ears very well, even when I'm moving around a lot. I did once drop one bud in a bowl of soup; I washed the bud cover and wiped the bud off and they function just as well as before. I gave four stars as I do miss having a volume and start/stop control on the cord and I hope that they include this functionality on future models.

### ⭐ weak, tinny and no bass, horrible
*by G***D on May 2, 2013*

These are just awful. The sound is overall very weak and tinny, all high frequency, and worst of all, absolutely no detectable bass - contrary to the direct claims of the manufacturer. I tried them for a week, tried all of the ear fittings, and tried very hard to find something to like about them, but couldn't do it. It's incredible to me that they get away with selling such an inferior product. I think the idea that nanotubes could improve sound quality is ridiculous, and it's borne out in this lousy product. Another nano-scam. I'm going back to my Sony MDR-W08. They don't have all the bass I'd like, but they're infinitely better than this nano-hyped piece of junk.
