About the Alpha Prime

The MrSpeakers Alpha Prime is the company's flagship closed-back planar magnetic headphone introduced in 2014 as an evolution of the Alpha Dog model. It uses a heavily modified version of the legendary Fostex T50RP planar driver, redesigned from the ground up to provide smoother frequency response, increased clarity, a wider soundstage, and faster, more linear bass with improved dynamics. The headphone features 3D-printed earcups with a chemically polished and automotive-grade painted finish available in Claret or Black. It includes plush lambskin ear pads and a leather head strap for comfort. The Alpha Prime offers a frequency response of 16Hz to 18kHz and an efficiency of 90dB/mW, weighing 440 grams without cable. It comes with dual-entry cables (6ft 1/4" single-ended or 4-pin XLR balanced), a metal stand, cleaning cloth, and a two-year warranty. The design emphasizes musical engagement with a dynamic, revealing, and addictive sound signature that is less linear but more lively and detailed than its predecessor. It is praised for its ability to connect listeners to music across genres, with a sound that is never overly polite but highly accurate and exciting. The Alpha Prime is considered one of the best closed-back headphones in its price range,99 USD.
