Product Description

The Mix Jockey Stereophone delivers bass-enhanced high quality sound in a sturdy package suitable for DJs and listeners on the go. Dynamic elements, constructed from 1.4 mil mylar for enhanced rigidity, minimize mechanical distortion and yield a full frequency response from 18-20,000 Hz. Anisotropic ferrite magnets enable the Mix Jockey to deliver great volume, even with low-voltage portable devices. Oxygen-free copper voice coils improve signal transmission and conduction for cleaner, clearer sound. Closed leatherette earcushions seal comfortably around the ears, improving bass performance and blocking outside noise. Closed cushions also prevent sound from leaking out of the headphone -- perfect for the dorm room.With earcups that rotate and fold in, the Mix Jockey collapses into a protective package that is easy to carry and tucks away neatly into small spaces like computer and gaming consoles. Volume control on the cord makes it easy to adjust the listening level when getting to the sound source is difficult, as when plugged into a computer or used in flight. The padded adjustable headband ensures a comfortable fit for any shape or size head. The straight, single-entry cord affords 8 feet of flexible movement. A gold-flashed 3.5mm (1/8") plug and a gold-flashed 6.3 mm ( ") adapter are included.The Mix Jockey is a great overall value and is ideal for listeners who demand high quality sound that travels well.

2.0 out of 5 stars Useful, but disposable..., December 19, 2006

The short: Don't buy a pair of these expecting to use them for the next five years, they simply aren't engineered that well (details follow). Buy them if you want a cheap pair of headphones that are easy to carry around, comfortable, block outside noise, and sound great.

The long: I've owned two pairs of these headphones over the past few years. My use consists of primarily listening to music. I'm not throwing them in a book bag every day, they usually stay at home by the computer, except for the occasional road trip.

The second pair recently broke (to the point where it was not worth repairing), so I decided to take it apart to see if I should purchase a third pair.

That said, here's how they fail:

1. ) The volume control in the cord breaks, and as a result, one or both of the speakers cuts out intermittently. Eventually, there is no sound at all. This happens consistently.

With the first pair, I tried soldering the wires back on--this lasted a few hours, until it broke again. The problem is that the weight of the cord pulls directly on the fragile solder joints--they will inevitably break off, no matter how gentle your daily headphone use is. The only solution is to cut the volume control out of the cord and tape the wires back together (I've done this once for each pair).

Unlike the volume control, the cord is properly connected, and requires a great deal of force to remove it (accidentally or intentionally).

2. ) The wiring in the headset breaks, and the right speaker works intermittently, then fails. This has not yet happened to my first pair, which I am still using (albeit, in a taped-together state) until I purchase a new set of headphones. I have stopped folding/collapsing it to try and prevent it from failing before I buy a new pair (NOT the same ones, I've decided).

In the headband, a curved piece of springy metal is stuck between two pieces of a foam-like material. This metal piece has four holes drilled in it (very poorly), and the wire to the right speaker is woven through these holes. The result is that whenever you fold/collapse the headphones, the wire rubs against the sharp metal edges, and the insulation wears away. Eventually it cuts through the wire (which is actually *taught* at the headphone's extended-most position), and it is not possible to remove and replace the wire without cutting and re-sewing the headband. The wire I removed from the broken pair was worn down to the bare metal in all four locations where it was woven.

Despite these engineering oversights (failures?), the headphones last for about a year before modifications/repairs will be required, and the sound is above average (bass is actually pretty decent). They are easy to carry and don't require very much power to get loud.

Just don't expect miracles for <$30.

These headphones are very comfortable and the sound quality is very high. The volume control on the cord is handy. Durable material, and a really good buy all around.

I've had these headphone for about two months now and they're a really good pair of headphones. I really like that they're foldable because they're easy to store in my bookbag. These headphones are loud and reduce noise quite nicely. Good Buy!!
