Very poor overall

Normally the reviews on Future Shop products have been quite helpful, but for this product they are deceptive. I've had a lot of headphones and earbuds over the years, including a nice pair of JVC's, and in my opinion these are on par with the dollar store ones. I have old sennheiser earbud set that blow these away across all frequencies. I can say that the low end is satisfactory for what you would expect from a cheap earbud set....but certainly not extraordinary as some have stated. The high end is terrible as one other review also stated, yet for some reason they decided to give four stars anyway. The midrange does not impress either. They make everything sound like it was recorded in a tin can. I have tried them with music as well as voice from audio books and radio programs. On the positive side, they are very sensitive so you'll get louder output from your portable devices and the cord is a nice length. But for me this hardly makes up for the very poor sound quality. I just hope i'll be able to return them as the cheap break-open plastic container that they came in required me to mangle to pieces just to get them out.

good bass

They sound really good, the bass is really deep sounds good the treble sounds a little noisy. But they are worth the price.

Went back and bought another pair

I was so impressed with these buds that I went back to the store and bought a second pair. Bass has a lot of oomph, treble is very clear and sparkling. Respond well to parametric equalization, and loud volume is not a problem. On top of the great sound, they are extremely comfortable (I usually have them in all night) and they stay in your ears really well. Great value.

Love these!

I always have bought skull candy headphones before but I think I've had like 3 or 4 in the past 5-7 years! It never fails that after awhile something happens with the wiring and one headphone doesnt work or cuts in and out. I even have made sure to be careful with them after this happening a couple times! So I got these JVC headphones and I love them so far! They stay in my ears way better than the skull candy ones (which stayed pretty good too). Also the sound seems more clear and less sound let in from the outside. One downside to them being so great at staying in my ear is when I go to take them out, I'm still used to just popping out the skull candies but these ones you sort of have to turn a bit and I'm afraid if I pull them too hard the rubber might fall off. So just watch out for that!
