With the CX-300 a lot of the noise around you is blocked out, so you can listen to your music at a normal volume. Another fantastic thing about these earphones is that you can’t hear people people around you unless they were shouting. That is what these earphones were built to do.

Product Features

Includes – 1 CX300 ear-canal headphones and 1 Ear adapter set (S/M/L)
Powerful, bass-driven stereo sound
Perfect fit in the ear canal due to ear adapters in different sizes
Brilliant attenuation of ambient noise
Ideal for use with all MP3, CD, DVD, MD players and portable game systems with 3.5 mm headphone sockets
So who are these for let’s look at that:
1. Someone who wants to shut out surrounding noise while enjoying their music. 2. Someone who like excellent sound quality. 3. Someone who wants to listen to music but does not want to wear something that feels like a helment.
Let’s take a look at the cons

The cord that comes with these it is long on the right ear and shorter on the left. It is not too terrible but some people don’t like that shape.
Cord noise. These cords make a noise in the wind or against clothing, that you can hear and it sounds like a rustling sound.
You might have a small bit of distress getting the 3 different sizes of silicone ear pieces to fit. You can get a slightly larger size and it should work fine.

When activated, NoiseGard active noise reduction drops steady-state low-frequency noise (from about 500 Hz and below) by 15 dB–which the human ear perceives as more than halving the noise–thus enhancing the clarity of your music. The noise reduction circuit requires 2 AAA batteries (not included), but the headphones work fine without the circuit engaged. Sennheiser’s fold and flip design lets you turn the ear pieces 90 degrees and fold the headphones closed. Their ported design lets them go more air for greater bass response.

The Basics:

The Sennheiser PXC 250 Active Noise Canceling Headphones are constructed of solid metal/plastic components, comfortable vinyl padding, folds up into a somewhat small and flat profile, and fits fantastic in the high quality padded case that comes with the headphones. The noise canceling circuitry is contained in a separate, it is not bulky at all to handle especially with the belt clip. The power switch is pushed up/down and you won’t have to worry about accidentally pressing the switch.

 It is powered by 2 AAA batteries (documentation doesn’t state how long the power would last with continuous use) and will conveniently continue to function even when the batteries drain (albeit without the noise cancelation). These headphones are not silver colores as stated and shown in the product title and picture, they are black and metal gray. The standard two year warranty is certainly an advantage over other headphone manufacturer offerings.

 Audio Quality:

With the noise canceling curcuitry turned off the audio sounds shallow and tiny because the padding causes the headphones to sit a small far from the eardrums. If you push in the headphones against your ears you will notice that the audio quality and bass response improves. When the circuitry is turned on the tinnyness disappars, but the audio seems over-boosted. Check out this site for the best reviews on Sennheiser PXC 250 Active Noise Canceling Headphones .

There’s more than one way to make a wireless MP3 player, and building it directly into a set of headphones may seem like the simple way out, but it gets the job done. Plus, there are none of those au. . .

The perfect gadget for when the screen on your mobile isn’t quite excellent enough to make out all the action. . . . as long as you don’t mind looking like someone from Star Trek who’s had to catch the bus.
