Customers like the quality of the headphones. They say that they have deep, smooth bass, excellent mids, and highs. They also mention that the build quality is pretty decent. Some customers say that the stock headband is okay, but it starts to make a hot spot on the top of the headphone. Overall, customers are satisfied with the quality and performance of the product.

Customers like the value of the headphones. They say it's well worth the investment, the drivers are phenomenal, and the sound quality is amazing for the price. Customers also mention that the headphones are built pretty well, making them feel more premium. They are forgiving enough to be on your head for hours, and exciting enough to play games.

Customers like the detail level of the headphones. They say it has great clarity, crystal clear, and crisp highs. They also say the headphones capture a lot of nuance that gets lost in other non-planar drivers. Customers also mention that the headphones are very competent in detail and separation.

17 customers mention13 positive4 negative

Customers like the performance of the headphones. They say it works well enough without an amp, and has stellar performance. They are usable, but not overly comfortable. They play well through unamped devices, but an amp makes them bloom a little fuller. They're a function first headphone, with great impact and bass/mid response. Customers say it has so much potential if you modify it right.

"...virtue of psychoacoustic adjustment (read: it's all in your head), they work well and the bass doesn't seem particularly bloated...." Read more

"...And these do both very, very, well. Amazingly well. Would I recommend these to gamers? Hell yes! Would I recommend these music lovers?..." Read more

"...But if you have a cheap headphone amplifier, they should come to life pretty well and get pretty loud...." Read more

"...The flat pads that come with the headphones were simply unusable for me...." Read more

Customers are mixed about the sound quality of the headphones. Some mention that the sound is amazing, has a deep bass, and a wide enough soundstage for good instrument separation. They say the music just came alive. However, others say that the quality is worse than their Sony MDR-7506 at twice the price, the mid bass is way too high, and the soundstage itself lacks a bit of seperation. They also say that they lack in sub-bass.

"...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..." Read more

Customers have mixed opinions about the comfort of the headphones. Some mention that they're great, comfortable, and improve both the comfort and the soundstage. They say that it gives your head a nice hug. Others however, say that they are super flat and uncomfortable. They also say that the ear pads are thin and uncomfortable, and can hurt a little after a while.

"...FWIW, I think these earpads are as comfortable as the Dekoni hybrid pads that came on the Dekoni Blues...." Read more

"...The M50x was too unbalanced in the bass/midrange and only semi-comfy, V6 was too sharp in the treble for me and also has terrible pads...." Read more

"...They are very well built, light weight, and so far I have no problem wearing them for long periods of time...." Read more

Customers are mixed about the weight of the headphones. Some mention that it's not too heavy, while others say that it is very frustrating to carry. The sound quality is good, and the headphones are fun with bass and beat heavy songs. However, some customers find the headphones to be bulky and heavy, making them frustrating to wear.

"...They are very well built, light weight, and so far I have no problem wearing them for long periods of time...." Read more

"...T50R's to shine, but you are stuck to a laptop as the SYMBA SONIC is not portable. It needs USB power to operate...." Read more

Customers are dissatisfied with the cable length of the headphones. They mention that the cable is pretty bad, has a terrible cable connector, and the connectivity of the cords is questionable. The supplied cables are of poor quality and provide intermittent connections. Customers also mention that they feel the stock cable feels very cheap and is short.

"...only gripes about the headphone are the pads, and the included cable could be a little better, but can easily be replaced with a good auxiliary cable..." Read more

"...Cable jack gets a lot of hate but the pair I have is tight and I cannot envision an issue unless you spent your time wearing it out...." Read more

"...The supplied cables are of poor quality and provide intermittent connections. The ear pads are thin and uncomfortable...." Read more

Incredible, especially for the money.

Incredible, especially for the money.
Rarely will I write a review for a product on amazon, but these definitely deserve the praise. For some background, I have a decent collection of audio gear and have been a music lover for over 20 years (since age 10).It was'nt until about 5 years ago that my interest in audiophilia elevated to where spending more than the average dollar for better sounding music was no big deal for me. My real journey started with the Panasonic RP-HTX-7 back in 2012, even being cheap, were real eye openers when it comes to sound. Since then, other phones came and went: audio technica M50x, sony MDR-V6, sennheiser HD598. Every one of them did'nt quite gel one way or the other. The M50x was too unbalanced in the bass/midrange and only semi-comfy, V6 was too sharp in the treble for me and also has terrible pads. The 598 has a huge bass deficit, but otherwise beats the other 2.Being not quite satisfied with those phones, I branched out to upgrade to a DAC (Schiit Modi 2 uber) and amps (fiio E11K, Schiit Magni 2 uber, Schiit Lyr 2). Around that time, I purchased Sennheiser HD600's, Mrspeakers Alpha Dog, NAD Viso HP50, and recently, these Fostex MK3's.Which do I prefer?Well, each headphone does different things, and can serve different purposes and become preferable for certain music genres. The HD600 you can listen to for hours and have unbeatable comfort and midrange, but lack any real wow factor (remember they are non-fatiguing in any way). The Alpha Dog is super isolating and super detailed but lacks a bit of punch. The HP50 is great for mobile and has wonderful impact and bass/mid response, but has slight congestion not only in fit but also in sound.Now the Fostex is a very different animal, and the cheapest of the four (by far). Its not very pretty and it needs a lot of power to get the desired sound it can produce. All of my mentioned amps can power it just fine, however.The biggest issue of these fostex is the stock pads are terrible (not sound, just uncomfortable). I had to change them to Shure 1540 alcantara pads (at the suggestion of a very helpful fellow audiophile). They rival my HD600 in comfort, and the sound appears unchanged from the stock pads.All these cons and required pad changing are quite discouraging, are'nt they? Well if they did'nt sound as good as they do, it would'nt have been worth it. They rank higher than the other headphones I own in sound quality.For comparison:-HD600: Best midrange. Has similar, but leaner bass presence, very small to no soundstage and is not as clear.-Alpha Dog: Best sub-bass, but lacks punch as well as slightly less clarity. This lessened clarity is made up for with a wider soundstage.It is less focused in sound imaging and is also heavier than the fostex.-Nad HP50: As good as it is at being portable, it costs twice as much and it is bested in all convievable areas by the T50RP MK3. I would'nt call the fostex a good portable headphone, however.The fostex mk3's signature is one of fun, clarity, and precision. The bass is my favorite part of these headphones. It is very present and mid-bass focused, sub-bass takes a backseat, but is not completely missing. For clarification; sub-bass is the deepest/lowest notes you will hear (think thumping rap and rumbling beats) and Mid-bass represents bass guitar, the low end crunch of electric and acoustic guitars. Mid-bass usually represents the meat of most instrumental music and drums..the MK3 handles it so, so well.The midrange I do not find to be lacking in any way, it just sounds natural. The treble is exciting and can be a tad bit sharp, but ultimately is clean and never dull or annoying. There is nothing offensive about the sound signature these produce, even if the soundstage is not very big.The only con sound-wise I can think of is the soundstage itself lacks a bit of seperation. Yes, you can hear everything and all the detail shows up. It just does'nt have a lot of 'space' around the instruments like the alpha dogs do. The fostex is so engaging, clear and fun that you really don't focus on that, however.I spent a month running these MK3's through my usual torture tests and found them to pass with flying colors. They are forgiving enough to be on your head for hours, exciting enough to make music pleasurable, and speedy/clear enough to retain lots of detail. Best of all is they nail the bass response perfect with no sign of muddiness. I happen to prefer metal music (and lots of rock), but I really listen to lots of diverse genres as well, and nothing sounds bad through these MK3's at all.Just incredible headphones for the money, the fact they outshine my alpha prime at 1/3 the cost is quite a feat!Recommended-----------------------------------------------------------------------------------------------------------------------------------------------------------------Update 02/26/2017: These headphones have certainly proven their worth. In the past 6 months, I have done the following:-Sold my Alpha Prime, the fostex are roughly equal.-Tried new headphones, including the Audioquest Nighthawk and Audeze LCD-X. Even for what they gave me in soundstage and resolution improvements, they still lost out in immediacy, engagement and fun factor. Fostex is still king!-Upgraded my amp to the Ifi iCan SE; the fostex needs the power and it is worth every watt you can feed them.-Recently upgraded these stock T50RP MK3 to the Mayflower V1 edition and they are EVEN better than before. Clearer mids and calmer treble.-Performed a simple mod on them to bring up the bass.-I like them so much now that I added some Carbon Fiber Vinyl wrap to customize their appearance(picture included). Also added a MrSpeakers comfort head strap. Now they are just perfect, perfect!

5.0 out of 5 stars Warning! Wrong description! Excellent headphones!
Reviewed in Sweden on November 1, 2023
I bought the T40RP from amazon but I also have T50RP and T50RP dekoni blue.
I like all of them but T40RP would be my pick if I only could choose one of them.

Important information:
T20RP is open.
T40RP is closed.
T50RP is semi open.

Swedish amazon have mixed the models up.
If the order says T40RP you will get T40RP but the T40RP is closed and not open as it says on swedish amazon.
Just order the right T20RP if you want open headphones and T40RP if you want closed headphones and you will be OK.

I love these headphones. The planar magnetic element is excellent and the T40RP is the perfect rock/hardcore/metal headphone in my opinion.
It is studio quality sound and a very light and comfortable headphone.
The first days the headphone will clamp pretty hard on the head and it should but soon the headband will adjust to the size of your head and feel good. Just use the headphone normally and it will adjust.

The T40RP has a lovely detailed sound without being too detailed, it is just right for every music genre I throw at it!

Don't believe reviewers saying that the T40RP is the least favourable of the three because it is purely fantastic with just the right punch.
Other reviewers suck, trust me, I got taste and style and listen to all music styles!

The T40RP can be driven with a phone and it is much better than the T50RP with just the power from a phone so if you won't use headphone amplifier or a premium music phone with a quad DAC and powerful amp like the LG V-series I suggest you stick to the T40RP because the bass is much more lovely if driven by a regular 3.5mm phone jack than the bass of the T50RP.
With a quad DAC phone or a good amp you can have a good experience with all of the TxxRP headphones, it is up to personal taste really.

Good luck and don't count the T40RP out, it is a fantastic headphone for punkrock, hardcore, metal and any energetic music while being no slouch at any music style!
