Fostex T20RP-MK3 overview

  • 1Description

Styled in an open-backed design, the RPmk3 Series T20RPmk3 from Fostex comprises a pair of stereo headphones. Their copper-foil etched polyimide film drivers utilize proprietary Regular Phase (RP) technology in order to ensure an accurate reproduction of sonic material, thereby rendering these open-backed headphones suitable for monitoring in studio situations. To ensure a full representation of the sonic spectrum, these headphones have a frequency response of 15 Hz to 35 kHz.

The RPmk3 series is an evolution of the RPmk2, and as such, features redesigned housing, head-pad, and ear-pads to further both comfort and maximum performance of the RP driver. These headphones are designed to highlight a deep bass timbre, and sport a detachable cable, which can be replaced if lost or broken.

Refined Fostex proprietary Regular Phase (RP) diaphragm driver using copper foil etched polyimide film and neodymium magnet
Maximum input level of 3000mW to comply with pro audio environments

    Fostex T20RP-MK3 reviews

    RPmk3 Series T20RPmk3 Stereo Headphones (Open Type) is rated 5.0 out of 5 by 3.
    Rated 5 out of 5 by from A perfect mix of clarity and deep bass! I got them a week ago and man this headphones pack a punch. I really wanted to try open-back style headphones for the experience so I went with these and I don't regret it. Best sound I've got from headphones under $$. Don't expect a bass that will make your head shake, these are open-back, they wont provide you with that kind of bass. They'll give you a DEEP BASS experience, meaning that the bass will sound clear, deep and powerful yet detailed. A bass that will make the music sound full without making you feel like you have a boom box stuck in your ear. The clarity of these it's a great thing. You can identify things you didn't know were in your songs. I have played classical, jazz, rock, metal, hardcore, trap, almost any genre I could think of and these babies delivered. If you have a good player that support FLAC files, prepare to be amazed by the T20RP's. They sound so good that you will start noticing how bad some music out there has been produced. They have a bit of a high impedance so I'll have to get a portable amplifier to take them to another level. They also look cool, some people may not like the look of them but I find it rad.

    Rated 5 out of 5 by from Bass-heads, look no further. great head-phone! If you listen to hiphop,r&b or any music in general, you need this. Bass is deep, both mids and highs are great. Headphone works ok with your mobile devices, but you will ge greatly rewarded if you power this with a amp.

    Rated 5 out of 5 by from Exceptional headphone for the $. Easy to mod to taste. Pros: The best compliment I can pay these are this: When I listen to music on them, I have yet to wish for more treble or bass or vocal clarity. They disappear on my head and I can just truly enjoy what I'm listening to. For the price, especially compared to the cost of other planar headphones, that is epic. Cons: I would suggest watching Z Reviews' Youtube video on all of the Mk3 headphones to get an idea on the differences and comfort mods between the three. ( - Children beware, there is swearing in the video.) I think his review is spot on, in just about every aspect of this. (Disclaimer: I haven't heard the 40RPs, just the 20's and 50's.) First Con: The stock earpads. They are super thin, and not very comfortable - but to be honest, not hurtful. They are essentially ON-EAR headphones with the stock pads, as your earlobes will make contact with the inner driver area. The Shure HPAEC1540 and 1840 pads are hands down the most comfortable and best sounding pads I've found for the T20RPs. I like the 1840 pads just a bit more than the 1540. Second Con: The headband is thinly padded. It isn't uncomfortable, but can be improved upon. I went with the Mr. Speakers leather headband, and they just float on my head now. No pressure points becoming sore after hours of listening. The hardest part of installing this was figuring out where in the house I left my screwdriver. Third Con: Sensitivity. These are not easy to drive. Your smartphone will not suffice. If you need an inexpensive amp, I suggest the Micca OriGen+, or one of the many Fiio products. I listen to mostly rock, classic rock, metal, edm, blues, and a limited number of jazz and classical tracks. I would describe my listening preferences as being 1/2 way between bass-head and audiophile. I love bass, want it loud, but do not want it trampling over the rest of the music. I purchased the T20RP Mk3.
