Fostex T50RP-MK3 overview

  • 1Description

Styled in a semi-open design, the RPmk3 Series T50RPmk3 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 semi-open 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 flat and clear sound, and sport a detachable cable, which can be replaced if lost or broken.

Semi-open type for flat and clear sound
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 T50RP-MK3 reviews

    RPmk3 Series T50RPmk3 Stereo Headphones (Semi-Open Type) is rated 4.8 out of 5 by 23.
    Rated 5 out of 5 by from Best headphones I've heard for less than $ Amazing sound, I believe this is the best sound you can find for less than $.I went to an audiophile show where you can listen to a large number of headphones, $ - $ range.This headphone offers fantastic high, mid, bass. It is mostly closed, so it is awesome for the office (very little sound leakage or interference). The downside is the sound stage is not as wide as an open construction.Nonetheless, out of all the headphones I auditioned, this one was heads and shoulders above the competition, easily until around the $ range.I am not comfortable spending that much on my own enjoyment, so I was ecstatic to hear the sound this headphone produces for $.I use an ifi Nano dac/amp combo and would recommend a headphone amp. I don't think you will enjoy this set without an amp. The ifi Nano drives this just fine and really delivers.I will be going through my whole music collection to hear bits I was missing. :)THANK YOU FOSTEX!

    Rated 4 out of 5 by from Clarity incarnate The only way I would consider using this is with a decent amplifier. Although for close to $130, this is a great product, especially if you already have an amp. If you enjoy a punch of bass, these are not for you unless you enjoy really controlled bass. These are absolutely fantastic for all classical style music. Orchestras, pianos, guitar, and the like. I highly recommend purchasing different pads for it. Specifically the ones I mentioned as these might as well be called on-ear headphones with the standard pads. Noise attenuation is not great, but then again, you aren't purchasing these for the isolation considering they are semi-open.

    Rated 5 out of 5 by from Excellent value for entry level planar headphones!!! Excellent entry into planar headphones for audiophiles and music lovers alike. Sound is relatively neutral with a bit of emphasis on treble. Benefits from a good amp to drive them properly. Build quality is on point for this price point. The stock pleather pads are pretty thin but not uncomfortable. The stock pads make these more of an on ear headphone. Luckily, they are swappable to increase comfort. The modding community for these headphones is immense. Would definitely recommend to anyone getting into audio.

    Rated 5 out of 5 by from Best Headphones The Best affordable planar magnetic headphones I have heard so far. Period. Great imaging, spectacular clarity, punchy low end. Really characterful! Very comfortable padded headband design that doesn't put pressure on your head, right amount of caliper pressure with stock ear pads that masks weight of headphones. Distinctive looks. Great that it comes with 2 detachable locking cables and a lot of aftermarket cables fit with T50RP Mk3.

    Rated 4 out of 5 by from Not worth the purchase unless you have an Amp Purchased these semi open headphones because I wanted newer better headphones for mixing music. FAIR WARNING you need a headphone amp if you're gonna use these for professional use. For causal listening on music that's already mastered and limited then the volume goes up to a decent level even on an iPhone. Aside from the pro which is amazing audio quality, there are many cons. 1. Need a headphone amp! $100-150 for a decent amp. 2. The amp situation makes these headphones immobile. Unless you like carrying extra equipment with you. 3. Not foldable. 4. The wire gives some static sometimes and you have to readjust it where it connects. 5. AMP! Unless you already have an amp, I see very little reason to pay $300 for headphone and amp for a very small increase in sound quality which will usually not make a difference cause of MP3s. ATH-M50x are worth more for less.

    Rated 5 out of 5 by from Best Headphones Period ! I purchased these headphones due to the fact that I've been one of those apple headphone users my whole life and my friends would brag about these to me non-stop saying how incredible they were, so i decided to order a pair and while I'm obviously no audiophile they sound incredible!!! They got here very fast, they weren't damaged in any way, they sound crazy amazing..... You cant lose going through with this purchase (:

    Rated 5 out of 5 by from Amazing Sound at an Amazing Price! After watching Zeos Pantera's incredibly positive review of these headphones on YouTube, I decided to try a pair myself. What an incredible bargain! These are the clearest sounding headphones I own, with very good bass, as well as excellent midrange and non fatiguing treble. Throw in the fact that they are planar magnetic, and you won't find a better value anywhere. Highly recommended!

    Rated 5 out of 5 by from Great bang for the buck These are a great introduction to Planar Magnetic headphones. They're good - if a little uncomfortable out of the box, but with a little modding - new pads, a bit of modelling clay on the baffle plates - they sound amazing. They are pretty no frills - stock earpads are super thin, and the cables they come with are..... unusual...., and they don;t come with any kind of case (which is fine, that would just make them more expensive) but the sound for $ is top notch. Not much info out there on modding the Mk3 compared to the Mk2, but adding modelling clay to the rear of the baffle plate really makes these sing. Tough to drive - recommend a headphone amp. Not really for portable use unless you have a portable amp.
