5 out of 5 eggsGood cheap Hphones w/heavy bass

Pros: - Price
- Heavy bass, I had to turn down all my equalizer settings...havent had to do that in quite a long time.
- Fits my fat head

Cons: Can't really give any cons considering the price point. But if I had to I would list the cheap plastic, but again you should expect that in this price range.

Other Thoughts: To sum up, if you got a fat head and want a pair of headphones under $20 with heavy bass, I don't think you can go wrong with these. very happy with my purchase.

5 out of 5 eggsDeath by cat.

Pros: To me these actually had a very "clear" sound. The cord was also long enough that I could stand up and walk a few feet from my desk without removing or unplugging. These also had enough give between the ear pieces that it didn't feel like my head was being squished or get headaches - I have a fairly large noggin.
The ear pieces were also large enough to be circumaural, and not only that but were large enough to not squish my earrings in a manner that was unpleasant. The product is pretty true-to-description.

Cons: The part that goes over the head is a bit painful - I made a cover for them and that was fine enough for me.
Keep away from cats that like to knock your stuff over, apparently a meager 6lb cat can break them.

Other Thoughts: I loved these until my cat knocked them off the arm of my chair and busted the left ear off.
Will be impatiently waiting for their arrival, the interim headphones I'm using suck.

4 out of 5 eggsBetter than BEATS headphones LOL

Pros: Love these headphones, I use for my gaming and basically dubsteping music. JVC always produced quality products and I remember using this brand as a kid in the early 90s. they are better against so called $400+ bucks BEATS by DR. DRE headphones($14 bucks material to make) LOL!

Cons: Very long cord but not really sure if its a con cuz I just tie it to make it short =)

5 out of 5 eggsVery good for the price

Pros: I've been using JVC HA-RX500 ($3 more than these) for 2 years, they were very good, solid build quality, I dropped and pulled them countless times, everytime thinking that this time I probably broke them. It never happened though. They were also pretty loud and the sound was properly good. I bought JVC HA-RX300 to have an extra pair and as much as they're worth the price, it really is worth spending those 3 bucks and getting the RX500. They're more sensitive, louder, crisper. Build quality is the same.

Cons: None really, just that they're only $3 less than the much better RX500.

Other Thoughts: Spend $3 more and get RX500.

4 out of 5 eggsDecent to Good

Pros: My last pair of headphones was "KossUR20" which lasted me a about 18months b4 dieing. This JVC pair has better bass and can hear a lil more detail then my last pair of headphones. the headbands and cups have a nice sleek design, something the picture in the product page failed to show in true color. over its a decent to good quality headphones.

overall is decent to good quality,

Cons: the band and frame of this headphones is thin and seems susceptle to breaking easily. my koss ur20 headphones that died had a robust frame. the audio sounds good but every now and then I can hear a very faint buzz like noise throught headphones. circumaural cups that cover the ears seem to be meant for small to medium size ears and not ment for large ears.

Other Thoughts: I have a tendacy to be rough with my headphones and since this frame seems thin and susceptle to breaking easy i hope that it last 18months or more from my last pair of headphones. i do like the design of style the headphones has and glad my ears are medium for the circumaurals pads to cover my entire ear.

5 out of 5 eggsGreat quality for Price

Pros: For the price I don't think you'll find anything better than these.

They sound great for the price, and I love the 8' cable it has. (I'm able to lean over to my mini fridge while on my computer without taking off the headphones). I wanted a cheaper pair so that I wouldn't have to worry about them and could just toss them next to my computer. Built with plastic hence the price but they are surprisingly durable.

Cons: No head padding
Little uncomfortable after an hour

Other Thoughts: I tore the cable recently after it wound around my spinning chair, so I decided since they are now ruined I would throw them on the floor to see just how durable they are. Throwing them on the ground with some pretty good force, I never broke them.

Great backup or medium-use headphones, if you're looking for something to use all the time I'd personally spend the couple hundred for a really nice pair. I could see these getting uncomfortable. Otherwise money well spent.

4 out of 5 eggsDecent for the price

Pros: Light, Long cord, inexpensive.

Cons: Can feel cheap to some, Bass is only alright.

Other Thoughts: I'm not an audiophile so I don't claim to hear the full range. In fact I have minor ringing in my ears occasionally so factor that in. But these are excellent for the price. You can't beat it for 20$ If you want inexpensive headphones, this is the place to stop at. I only with it had an audio adjustment wheel on the them.

2 out of 5 eggsNot worth the retail price

Pros: OK deal when on sale.

Cons: Muddy sound -where are the mid-ranges and highs. No brassyness in the the horns, no transparency in the violins. My $10.00 over-the-ears sound better.

Feels cheaply made for a $49, circular ear pads fits poorly.
