Stereo Headphones From Sony

We looked at three of Sony’s new headphone products for use with portable audio applications.
As part of our growing coverage of all things audio, we decided to have
a look at the choice in headphones suitable for portable audio
applications. For this we picked three quite different portable
headphone/earphones from Sony.

The MDR-Q66LW are a pair of portable headphones that hook over the back
of the ear and provide a good listening experience without anything
inserted into the ear. The downside is that they do not feel overly
secure on the ear and are thus more suitable for passive pursuits, like
lying on the beach, rather than anything even slightly active.
Additional features include an adjustable, retractable cord to extend
and retract the cord for storage purposes. The Texture Type Cord also
prevents cord tangle.

The MDR-EX81LP/B earbuds are designed to deliver deep bass and clear
treble sounds. They are a comfortable fit and the cord has an extension
plug that allows you to choose the length of cord depending on the
application. For example I found that with the extension removed it was
a perfect length for placing my MP3 player in my shirt pocket whilst
with the extension it was ideal for putting the player in a jacket side

Carrying Case

The MDR-NX1A/WHITE neckstrap earbuds provide a secure and comfortable
way to both listen to your audio and to carry your MP3 player. The
in-the-ear design fits snugly, yet comfortably inside your ear,
eliminating the need for a headband. You can enjoy music while
exercising, traveling or working at the office, and the soft, silicon
earbuds are very comfortable.

Across these three headphone types you have a good cross-section of
what is available, apart from the headphone type with the band over the
head. I found both of the earbud types very comfortable to use for
extended periods. On the other hand, the comfort level of the Q66 was
so much higher since there is nothing inserted in the ear canal, but
felt heavier on the ear and much less stable for active pursuits. So I
can recommend all three of the headphone types reviewed here. The
choice comes down to active or less active, and then if active, whether
your MP3 player is best hung around your neck, as with the NX1, or in
your pocket or on an arm strap, with the EX81.
