As a self-professed audiophile, I take great interest in the sound quality of the music I listen to. A good set of headphones is a great way to immerse yourself in the music by getting the speakers very close to your ears and simultaneously blocking outside noises from interfearing with your listening experience.
If you are looking for a good pair of full sized headphones, look no further than the Sony MDR-V6. These are full size, circumaural, closed back headphones. This means that they completely surround your ears, with big soft pads that rest on your head. Closed back means that they attempt to seal the sound inside the cups, limiting anyone around you from hearing what you are listening to and simultaneously blocking outside sounds from getting in to your ears.
The Sony MDR-V6 are very comfortable to wear for long periods of time. The pads rest directly on your head, with no part of the headphone making hard contact with your ear. The pads themselves are a soft, artificial leather-like material. The pads are user replaceable in the event that you tear one.
The MDR-V6 has a very long, coiled cord with an adaptor that allows them to be plugged in to the smaller and more common 1/8" plug found in all portable audio players, as well as the larger 1/4" plug found on higher end home amps. The cord itself is quite long and stretches out nicely, allowing you to sit quite far from your sound source. Also nice is that the cord only enters the headphones on the left earpiece. This allows you to take them on and off without the cord tangling in your clothes.
I find the sound quality of the Sony MDR-V6 to be excellent. They are not overly bass-heavy, but they can certainly thump along with the right music. Dynamic range is excellent, with highs ringing out clearly. Midrange and vocals come through clearly and sharp. Better sound can be found in professional level headphones, but you'd have to pay A LOT more to see significant improvement in the audion quality.
The headphones fold up quite well, with both earpieces flipping in and compacting the entire headset down to a more manageable size for storage. Both earpieces are also able to be compeletely inverted and fliped to face outward. At first this may seem like odd, but it allows you to hold the earpiece to your head on one side if you want to take a quick listen without putting the headset on. Nice if you are talking to someone and listening to something at the same time.
The MDR-V6 also comes with a leather carrying pouch - a thoughful addition and much appreciated if you travel a lot like I do.
For the money, you will be hard pressed to find a better deal that the Sony MDR-V6 headphones.
