Beyerdynamic Custom One Pro

by: beyerdynamic

The Beyerdynamic Custom One Pro is the first Manufacturer 'factory custom' headphone allowing the listener to select 4 different stages of low-end response shaping with 'semi-open' or closed-back operation at the flick of a lever. The cosmetics of Custom One Pro are also customizable with different outer cup metal faceplate designs and/or colored earpads cushions available separately from Beyerdynamic. Cabling selection is equally personalized with after-market choices to include a mic'd Apple iPhone/ smartphone cord or varied headphone cord lengths. The Custom One Pro sound is highly impressive and bests other closed-back cans at over twice the price. Made in Germany.

  • The Beyerdynamic Custom One Pro is the world's first European 'audiophile-level' headphone offering four bass response settings plus a huge array of cosmetic options and varying cord choices for after-market personalization. De-tented sliders at the bottom of each earcup provide four positions ranging from 'Light Bass' to 'Linear Bass' on setting 2 to 'Vibrant Bass' on position 3 and finally serious basshead-rocking 'Heavy Bass' on position 4. The first thing we noted is the Custom One Pro FR bass reflex tone-shaping actually works well and effectively alters the tonal character of the headphones from an analytical and fairly 'dry' signature sound to a booming, very richly extended low-end presentation delivering up to a massive 20dB of bass boost. The response curve flattens at approximately 300Hz on all settings leaving the midranges and upper highs mostly untouched by the low-end shaping. The Custom One Pro's 'semi' closed-back earcups provide a good degree of environmental ambient noise blocking and solid audio leakage protection, so those around you won't hear your music emanating out of the cans. Although ostensibly designed for effortless volume from smartphones, iPad and tablets, the low 16 Ohm impedance combined with tough 96dB sensitivity specs make this headphone sound audibly more impactful and cleanly dynamic under the drive of a good headphone amp. The acoustic performance of the Custom One Pro simply shocked our HeadRoom team. Frankly, we were maybe expecting a cheesy, washed-out signature with either bloated one-note bass textures or the 'wooshy' presentation often heard with other bass-port cans. We could not have been more wrong. Although its not perfect -- there's a slightly uneven tone in spots -- the pointillist, well-defined musical resolution and overall clarity of detail combined with the sonic personalization and outstanding build quality makes the Custom 1 Pro one of our favorites ever from Beyerdynamic, and the affordable price is just as equally remarkable. A rare unanimous HeadRoom team recommendation for any music lover seeking a great closed-back headphone.

    The Beyerdynamic Custom One Pro headphone comes in a matte-black finish with the red/white Custom One logo neatly emblazoned across the detachable metal faceplates on the outer earcups. Four screws on each faceplate allow either reversing the faceplate to an aluminum metal look sans logos or easy switching with your own custom-designed faceplate when/if you choose. We have been highly impressed by the caliber of workmanship and superior materials found on this extremely well-priced headphone. A beefy but light black-anodized aluminum headband assembly with tough-built earcup yokes promises extra long-life durability. Earpad cushions are a soft, plush leather-type material. Moreover, nearly every single part on the Beyerdynamic Custom One Pro is easily owner-replaceable, guaranteeing this headphone will stand the test of time and daily use. The Custom One Pro has a detachable headphone cord; a mic'd cord for Apple iPhone/iPad /iPod Touch is available from Beyerdynamic [sold separately by Beyerdynamic]. The included headphone audio cord is 5ft long and terminates to a straight gold-plated 'mini' 1/8 inch [3.5mm] stereo jack. A screw-on 1/4 inch stereo plug adapter comes provided on the cord. Free 2-year premium 'repair or replace' manufacturer's warranty with your HeadRoom 'authorized Beyerdynamic dealer' purchase receipt. Fabricated, engineered and assembled completely in Germany.
