Comments about Beyerdynamic Custom One Pro Headphones:

These headphones are great. They have a slider on each earphone with 4 different settings to adjust the sound signature. Adjusting the slider opens or closes port holes that change the way the driver behaves. With the 3 ports completely open these things have tons of bass and are tons of fun to listen to. Progressively closing the ports you start to reduce the bass and emphasize other frequencies. With one port open anything with a guitar sounds amazing and vocals are very clear too.

The headphones are great because you can change their sound profile to whatever suits your music and/or mood best. With the ports completely they have more bass than Beats by Dre and the rest of the music sounds much clearer. They plug into any portable electronic and don't require any amplification which sets them apart from many other headphones of this caliber.

After buying and returning a different pair of high end headphones I loved these right away. It's great that they are so customizable and allow you get the most out of your music. I use them mainly at home while I study and while streaming lectures for long periods of time. They isolate noise pretty well so I can't wait to have these on my next flight. They're pretty comfortable and don't bother me while wearing glasses which is a plus.
