The ER4 series, made up of the ER4S, ER4P and ER4B have been Etymotic's top-of-the-line canal phone series since their introduction in 1991. The ER4P are specifically targeted towards more mobile and/or value-oriented consumers, with their enhanced bass response without the need for cumbersome and often expensive amplification. Utilizing rubber triflange or foam tips the ER4 series are designed for outside noise reduction, and audiophile level sound quality. A good pick for those who desire high quality sound reproduction, yet also travel often or simply wish to listen without the discomfort and risk of listening at high volume levels.

Pros
- Above average sound quality, but can be muddy in comparison with other headphones of similar price range.
- Very good sound isolation, nearly everything from the outside world is muted with these headphones in your ears.
- Hard carrying case is sleek and very stylish. In addition, it is very durable and has good build quality. Serves its purpose well, but can be a pain to carry around due to its size.
Cons
- Annoying shape and size, can be a pain to put in and out.
- Wire, although relatively decent in strength, is made of odd material that has a strong chemical odor, and contorts to annoying forms very easily.
- Bound for breakage and potential defective soldering in the left earbud. As with what happened with my pair, and with the pairs of others on the web, the left earbud becomes detached completely, and parts of the insides (including the soldering) are ripped out. Left earbud, by itself, is not sold as a replacement; this type of damage is extremely easy to encounter, not necessarily due to rough handling or misuse.

At $179, the q-JAYS match or best other earphones at its price point. Touted for their small size, the q-Jays are an amazing choice for a travel or on-the-go headphone as...

The MDR-EX700LP is Sony's flagship dynamically driven IEM. Marketed towards consumers and audiophiles alike, the MDR-EX700LP has been recently updated with a new multiple layer diaphragm to further improve the sound quality. At $299, the MDR-EX700LP is a strange beast. While not providing any isolation for use on-the-go, a full sized headphone at this...
