Summary: Like many of you, I always used the headphones or earphones that came with my audio player. If they broke, I went to the local store and bought something simple (I don't want something too fancy) that looked about the same. Those new earphones sounded about the same and so everything was fine. I continued listening to music.

After a while, I began reading on the internet about these certain headphones, EP-630's being one of them, as having extraordinary sound and an amazing value. I still wondered what the difference would be; after all, they are earphones. You can't fit a 5 foot speaker inside a 4mm hole.

When I found a good deal on these, I decided to leap in and find out what everyone was talking about.

I will never go back again.

These headphones sound like a home theater system in your ear! Mind you, this is coming from a person that has listened to cheap headphones his whole life, but I think many of you are in the same boat as I am. I have a number of stereo and surround sound systems at home, but never upgraded my headphones for some reason. I guess I just didn't think they could really fit decent sound in something so small. This blew me away.

These earphones provide crisp, clear bass. The treble is not tinny like cheap earphones, but rather more balanced. These earphones cover the whole range- treble, midrange, and bass - fairly well.

The plugs seal your ear well, which helps with the sound quality. There aren't a lot of outside sounds coming in, and soundwaves stay in - which means you don't have to blast the volume just to listen to your music, which very much helps the quality.

They give you extra plugs (both bigger and smaller) in order to give you a perfect fit if these don't stay in.

The cord is soft and flows naturally with you, unlike some cheap earphones.

This may sound funny, but the plastic clear case it came in is durable enough that I use it to house my earphones when I throw it in my bag.

The quality of the sound is outstanding. For this price, it's worth trying. It's the best value for earphones on the market - similar ones range from $40 - $120. This is a great deal.

Don't wait. If you need new earphones, get this. You won't regret it.

Summary: Bought EP-630 for few days and I really like it. The noise isolation really works. I can enjoy music on streets or my office with low volume. I figured it's good for my ears. For the low price tag, it is really a good buy.

Summary: These earphones fit comfortably in your ears for extended periods of time. The sound is great, although i have not tested it yet while flying on a plane. I have these to replace the earphones that come with the Ipod. There are three adjustable earbud sizes that come in the package. Overall a good buy for EP earphones with an affordable price.
