With MP3 players and other portable music devices becoming more and more common, the companies making earphones have also been busy at work making better and better models to enable people to delight in their music even more.

If you have bought a brand-new iPod or other MP3 player, the earphones that are included are often cheaply made models. This is to be expected with any free earphones; and the cheaper models usually don’t produce particularly excellent sound quality.

If  you’ve already invested quite a lot of money on the MP3 player, it’s a excellent thought to spend a small bit more purchasing  quality earphones to listen to your music through.  The Sennheiser CX300-B Earbuds produce some of the best quality audio of any earphones in their price range.

For the audiophiles among you, the main features boasted are:

They produce accurate tone throughout a wide frequency range.
They have a 112 dB sound pressure level, which means it’s simple to block out noise in the background and really delight in the music you are listening to.
Their bud shape means that they fit directly into the ear canal, again limiting background noise. A minor point about this is that when using them outside, it’s vital to take notice of your environment and not get hit by a car that you didn’t  hear coming!
They have a standard 3.5 mm plug, which means they are compatible with the vast majority of audio devices.

As the Sennheiser CX300 B Earbuds offer some of the greatest audio quality in their price range, when using them to play MP3s, it’s vital to give at least a small consideration to the “bitrate” of the file you are playing.

MP3 files contain compressed audio and the lower the bit rate is, the more data is lost (and hence the lower quality the audio is). To really get the most out of these earphones, it is a excellent thought to encode your MP3 files at least at 256 Kbps.

Really, for the price, the Sennheiser CX300 B Earbuds are some of the best in the range and by coupling them with excellent quality MP3 player you will experience music on the go in a way that you have never been able to before.

Noise Cancelling Headphones have become extremely well loved with travelers and those that really just want some peace and silent when listening to music. Well Sennheiser has made an brilliant pair of headphones that are perfect for this type of use.

The headphones are extremely comfortable, light weight, and are most effective in blocking out noise. My main point for buying these headphones was so I could listen to my music and hear the instruments clearer. I got what I was looking for and much more.

First I despise small headphones, these completely covered my ears. I also noticed there was no buzzing or static when listening to any type of music. The buzzing sound can be a huge complaint among noise cancelling headphones. I was also amazed at the sound quality. My music tastes vary from hard rock, jazz, and classical. Each type of music sounded surprisingly fantastic. I have never been able to hear the instruments so clear before.

Sennheiser is really one of the best manufacturers in making headphones that block out noise. Although you can’t completely block out the noise on a subway or bus it helps tremendously is reducing it. So now I can listen to my music and not blow my ears out from having to turn the volume up so high. I was really able to tell the noise reduction feature when using the headphones on a airplane flight. It completely drowned out the noise of the engines and which allowed me to get a few hours of rest.

In conclusion Sennheiser is a very reputable brand. You know if it is excellent enough for DJs then it is the right choice for you. Although they are priced a small high you will be paying for a fantastic deal of high performing features in a pair of headphones.

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).
