Before I start my review, I would like to Thank Beyerdynamic US for providing me with a review sample.

sound slider to adjust amount of bass; lightweight and comfortable; detachable cable; great smooth sound

doesn't fold; no storage case

It's always refreshing to review a pair of headphones that appears to have a dubious gimmick, only to discover that the gimmick is actually a useful tool. Musicians, engineers, and home audio enthusiasts have plenty of reason to check out the Beyerdynamic Custom One Pro, which at $249.00 (direct),...

The Beyerdynamic Custom One Pro headphones look and sound like a standard set of cans, but they're much lower impedance than many similarly designed headphones, rated at just 16 ohms. This means that they can be driven quite happily by a mobile phone or MP3 player.

The Beyerdynamic Custom One Pro delivers an adjustable sound signature that ranges from flat to big bass, but always sounds clear and powerful. (4 out of 5) Pros Powerful, accurate, and clean audio performance, with four listening modes ranging from near-flat response to heavily boosted bass...

Got this set in October. It worked for about 6 mo, till one side start showing problems with sound level. NCIX does not deal with warranty for this brand, so have to send it for a repair to dealer in MA, USA. May just look for different brand instead.

Although the Custom One Pro Plus headphones, the latest over-ears from Beyerdynamic, have many admirable traits, the name alone sets rather high expectations.

Solid; balanced sound; Big; open soundstage; Detailed treble; Robust build; Customisable design

Need more excitement and dynamic flair

Only used them for 2 days so far and clarity is great.. I'm using setting 2 for bass.. Sold my Beats PRO by Dre to get these.. These seem a little weak to my Pros so I'm not sure if these have a break in period or not, I my have read somewhere there is..

The Beyerdynaomic Custom One Pro cans are big and sturdy but how do they sound?

Superb sound quality; Big; comfy earcups; Adjustable bass

Big and bulky

After extensive testing, it's clear that the Beyerdynamic Custom One Pro Plus should not simply be written off as a gimmick due to its optical redesign capabilities. With the "right" bass setting, its playback characteristics are impressive and balanced.
