## Description

The Fostex RPmk3 series headphones are successors to the reputed RPmk2 series that have been used as reliable monitor headphones in many professional recording studios for more than 30 years. The driver unit incorporating the key Fostex proprietary Regular Phase (RP) Technology diaphragm has been refined to achieve sharper audio reproduction for more accurate monitoring. The housing, ear pads and head pad have also been redesigned to derive the maximum performance of the RP driver. Founded in 1973, Fostex is an acclaimed manufacturer of location sound, multi track recording, and speaker products.

Review: Great value for the money - once you replace the ear pads! **Update: I've since obtained a set of Dekoni Blues (modded T50RPs), and between them I prefer the stock T50RP. The Dekonis do have more sub-bass, but the bass is boosted everywhere and seems a bit loose in comparison to the stock/un-modded T50RP. That said, I have used the Dekonis for a few hours straight where, possibly by virtue of psychoacoustic adjustment (read: it's all in your head), they work well and the bass doesn't seem particularly bloated. But I did not experience the same instant feeling of "I love these!" when I tried the Dekonis that I did with the stock T50RP. For reference, I had not been listening to the stock T50RP that day prior to unboxing and listening to the Dekoni, so my reaction wasn't based on a direct comparison. The Dekonis sound a lot more like the Audio-Technica ATH-M50X - I did a very brief comparison and they're not the same, but they have some similarities. Again, my point is to say that the stock T50RP sounds pretty good out of the box, at least as far as it suits my listening preferences. Got these on a lark after reading & watching numerous write-ups/posts and videos about these and their modded progeny. As others have noted, the stock pads are not so great. Besides not providing a seal for your ear, they also allow your ear to touch the inner ear cup, something that leads to physical fatigue after a while in my experience. However, the $35 ear pads I got here on desertcart (https://www.desertcart.com/gp/product/B07X1L287G/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1) resolved those two problems, and I find myself really enjoying these cans. FWIW, I think these earpads are as comfortable as the Dekoni hybrid pads that came on the Dekoni Blues. Doing a direct comparison of the Fostex T50RP, Sony MDR-Z7M2, and Sennheiser HD 560S using Wye Oak's "Sick Talk" from the Shriek album and no EQ: the Sony has the best sub-bass extension and bass slam - but it can get a bit muddy too; the Fostex has slightly brighter treble than the Sony, and solid bass with good impact, though it doesn't extend as far as the Z7; and the Sennheiser sounds like the most neutral (flat) with somewhat airier soundstage, the brightest treble, and the least boosted bass - the treble is not overwhelming, nor is the bass lacking. Overall, I think the Fostex strikes the best balance on this track, based on my listening preferences, which probably explains why I have been having so much fun listening to these cans since I got them almost 2 weeks ago. One caveat: As others have noted, you will need a decent amp to drive these as they're not terribly sensitive. I've mostly been using a Topping A50S, with the volume around 1 o'clock in low gain mode. For the 3 headphone comparison today, I used a Monoprice Monolith 887. For the Fostex, I set it to medium gain as the volume knob was almost maxed out in the low gain setting, whereas the Sony & Sennheiser were fine on low-gain. In conclusion, I really like these headphones, and more than I thought I would. In fact, I don't even remember what I was expecting when I ordered them other than that I'd probably have to mod them a lot to make them sound good and I was willing to tinker. And I did tinker a bit: but with just a pad swap they are greatly improved over stock, and so much so that I don't want to take them apart. Now I really want to hear the Dekoni Blue & Modhouse Argon!
Review: Piloto le mie Fostex T50RP con uno stack Focusrite solo con amplificatore Topping L50 senza alcun problema. Le Fostex T50RP sono cuffie ad alte prestazioni che offrono un'esperienza audio eccezionale, rendendole un'ottima scelta per gli amanti dell'hi-fi e gli audiofili. Le cuffie eccellono in diverse aree: Qualità del suono: Risposta in frequenza ampia e dettagliata: Le T50RP coprono un'ampia gamma di frequenze, dai bassi profondi agli alti cristallini, con un'eccellente riproduzione dei dettagli. Suono neutro e bilanciato: Le cuffie offrono una presentazione sonora neutra e bilanciata, senza enfatizzare eccessivamente alcuna frequenza. Imaging stereo eccellente: La scena sonora è ampia e spaziosa, con una precisa collocazione degli strumenti e delle voci. Comfort e vestibilità: Design leggero e confortevole: Le cuffie sono leggere e comode da indossare anche per lunghi periodi di ascolto. Design aperto: Il design aperto permette una buona circolazione dell'aria, evitando il surriscaldamento delle orecchie. Costruzione e qualità: Materiali resistenti e di alta qualità: Le cuffie sono costruite con materiali resistenti e di alta qualità, garantendo una lunga durata. Design modulare: I componenti delle cuffie sono modulari e possono essere facilmente sostituiti in caso di necessità. Cavo staccabile: Il cavo è staccabile, il che aumenta la versatilità e la durata delle cuffie. Punti di forza: Qualità del suono eccezionale Design open: sentirete il corriere suonare anche con le cuffie indosso! Comfort e vestibilità da buoni ad eccellenti, dipende se lasciate il pad di seri Costruzione e qualità elevate Cavo staccabile Punti deboli: Mancanza di isolamento acustico a causa del design open Design non adatto a tutti i gusti, i dettagli in metallo e il colore arancione sono un po' polarizzanti. Cuscinetti auricolari: I cuscinetti auricolari inclusi non sono eccezionali, io li ho sostituiti immediatamente con dei pad in memory foam in pelle, che potenziano ulteriormente i bassi grazie ad una sigillatura del padiglione superiore. Prezzo a volte elevato, dai 140 ai 180 COMPRATELE! Spesso vanno su, ora sono a 250 euro. In definitiva, le Fostex T50RP sono cuffie ad alte prestazioni che offrono un'esperienza audio eccezionale. Sono un'ottima scelta per gli amanti dell'hi-fi e gli audiofili che cercano cuffie comode, resistenti e con un suono eccellente. Tuttavia, è importante tenere conto del prezzo elevato e del design aperto, che non offre alcun isolamento dal rumore.

## Questions & Answers

**Q: How is the sound isolation?**
A: Not good.  If you want isolation, try T40RP MK3.  They are closed and should provide better isolation and they use the same driver as the T50RP.

**Q: Can you compare sound quality to sennheiser momentum 1.0? I am looking for my first open back headphones.**
A: The T50RP is the semi open model and considered the most neutral sounding. The T20RP is the open back model and considered to have the most bass. The T40RP are the closed back model. As other have said an AMP is recommended these require a little power to drive. Probably the most power hungry headphone I've owned.

**Q: How hard are they to power? Will fiio x3 (first gen) handle it?**
A: I have a Hiby r3, Hiby r6 Pro and a FIIO X3 II.  The FIIO has significantly more power and drives the T50RP rather well.  I am modding the T50RP to balanced to see if the Hiby's can provide more juice that way.  I don't like running 100% volume for not enough drive strength.  FIIO is a strong little bugger!

**Q: Can the smsl sd793-ii dac/amp combo power these to a modest level (not painfully high)?**
A: I'm not sure this helps, but I use a Fiio A3 Amp w/ my Fostex... it gives nice even highs/lows amplification. I use it w/ an iPod nano, samsung phone, and nexus tablet... my computer and laptop drive the head phones fine w/o the amp.

Imaging is very very good. Very accurate sound at high volumes. Punchy. Nothing is out of place just nicely balanced clean dynamic sound. Ear pads are silly thin and will get you by for a while but they will want swapping by most people to get a better, deeper fit and a slightly richer sound profile. They are 50 ohms but need alot of power to reach their potential. 1w at 50ohms is enough to get a great sound out of them but 1.5w at 50ohms would be perfect. I run them on a fiio k5 pro at about 3 'o' clock on the dial, so not much left to go at all and it's not silly loud but it's enough to damage your hearing long term so it's perfectly acceptable running on a k5 pro. Honestly, if you have a good amp already, these are well worth the money.
