No in-ear headphones at this price are ever going to compete with expensive, well-engineered, well-built items - that's just the way it is. But unless you're a total audiophile, these JVC items will be a pleasing purchase for most people. They come with a few different sizes of foam rubber earpiece covers to cater for earholes ranging from those the size of a pencil lead right up to full-on channel tunnel monsters. Being in-ear headphones, they do block a remarkable amount of ambient sound, and having worn them on several transatlantic flights now, I find myself wondering why I ever paid a couple of hundred bucks for noise-cancelling items. These use the most basic principle there is - block the ambient noise - and for this price they work pretty well at doing that. So much so that I now wear them under my helmet when riding my motorcycle too - they're small enough to fit without any bother, and I can listen to music whilst on long motorway treks or blasting up deserted mountain passes.
The supplied cord is a little short for my liking though - JVC could have done with adding another 20cm to it.
The sound quality is good, although it can get a bit 'woolly' (for want of a better expression) from time to time. The bass and treble are nicely reproduced for most music types without being too boomy or too tinny. JVC have struck a nice middle ground here. I'm sure your original edition Wagner or Beatles vinyl won't sound any good through these headphones, but plug them into your insert-generic-name-here MP3 player and they'll more than suffice.
I'm really impressed with these headphones. Pulled them out of the box, plugged them into the iPod, and they have a great sound. I started out with some Edgar Meyer from Uncommon Ritual, and they gave great detail and tonal quality. Then I switched to Beastie Boys (Hello Nasty), and I'm just blown away. Lots of layers and details that I never noticed before. The high end is crisp but not painful, and the bass is low and solid. They didn't catch quite all the low end on the first track, but I think it takes a 12" sub with a few hundred watts to do that adequately.
Anyways, all this is just with relatively high quality mp3's on a 5th gen 60GB video iPod. I can't wait to break the headphones in for a few weeks and then try them out with a nice hi-rez source like SACD or DVD-Audio. Or maybe even the NIN Ghosts blu-ray. Should be quite an experience!
Also, other than the fact that I have great sounds piped directly into my ears, I can barely tell that I'm wearing headphones. The medium buds fit me perfectly, and these things are feather light. Actually, I think I've seen heavier feathers. There are no pressure points on my ears anywhere to tell me that I'm wearing headphones. Quite nice! Most of the bulk of the bud seems to be there just so that you can grab and manipulate them. The cord material is also quite nice, as you can't hear very much noise transmitted up them as you move around (bumps and vibration as the cable drags across your shirt as you turn your head, for instance). Other bud earphones have a huge problem with this.
Overall, I'm quite impressed and glad I took the giant $26 leap, heh.
I strongly recommend these earbuds because of the sound quality which is very nice for the price range i have tried other brands before like Sony, Koss, V-Moda which are way more expensive and don't sound quite as good, these one however fit comfortable on the ears, when i am on the tread mill working out, i can not hear the music on the background that they play at the gym, some other earbuds i tried on the past would make my ears feel uncomfortable after a while, the JVC Micro HD Headphones won't do that, regarding the sound quality the bass is rich and the sharps are very nice, for the money you can't go wrong you will enjoy these earbuds
I was simply looking for a decent pair of earbud earphones to use at the gym with my iPod Touch. The lousy earphones that Apple shipped with the v1 Touch kept falling out of my ears when I would run on the treadmill, so I knew I had to get "earbud" earphones that actually fit into the ear. These fit the bill nicely (no pun intended). They never fall out while I work out. The only slight against them is that when you pull them out of your pocket, the small foam guards may fall off. It's not the tendency, but it can happen.
Other than that, these where a great little pair of only $27.
I purchased the JVC Micro HD earphones to use when I am relaxing in bed listening to my IPOD. I use them in place of my Bose Q2 headphones. The Bose Q2s are a bit large unless you are sitting up. The Micro HD earphones are very lightweight and comfortable to wear even when lying on a pillow. The sound quality is not as good as the Bose Q2s but very acceptable especially since the price of the JVC set is significantly lower. I highly recommend them over the standard IPOD earphones.
