The sound quality is quite good, but the Plug feels flimsy and doesn’t do the greatest job in regards to noise cancellation.

The WH-600 is a solid headset. Its performance for phone calls is above average, but audiophiles won't be impressed.

While they do have an attractively low price tag, you'd be better off spending a little more and getting a pair of headphones that offer better sound quality.

A decent pair of earphones, but they are a tad expensive.

Philips' SHE9700 offers a good option for people looking to try their first IEM. While audiophiles won't be impressed, less discerning listeners will appreciate the small comfortable design and good quality audio.

An attractive pair of entry-level IEMs, the Philips SHE9800 headphones won't blow away audio enthusiasts, but their sound is relatively well balanced and the wide sound stage is excellent.

The HS520 look good, but that’s about as far as it gets. Even though they aren’t overly expensive, you can get a far superior product for little more than what these are worth.

If you’re looking for a reasonably priced set of headphones that are unique and deliver excellent sound, the Philips Extra Comfort are highly recommended.

Philips' SHE9850 headphones are another strong entry into the mid-range IEM space. Their bass could be a little punchier and more controlled, but for the price these IEMs offer a clear, smooth and well-balanced sound.

The poor audio quality of these headphones, combined with the uncomfortable design, doesn't make them desirable. There are better portable headphones on the market.

The PMX 100s are a great portable headphone, offering reasonably balanced and exceptionally detailed sound.

The PX 100 are an excellent set of portable headphones that would be ideal to those who travel constantly and require a comfortable set of quality sounding headphones.
