    I recently purchased a T70P and would like to change the pads in a attempt to accentuate the flat bass. Anyone have any experience and or preferably any measurements with pad changes to these? Should I stick with a beyer pad? Or maybe a Alpha pad (even though I don't really want to spend that much!)? M50X or HM5 are also a possibility. Should i look for something with venting underneath? What frequency area do the vents effect? Thanks!

    Hey!

    Sorry no one has responded to this. Honestly, you won't find a whole lot of love for beyerdynamic on this forum, and it's partially due to what you're finding.

    The tonal balance of the T70 is so treble tilted it ends up sound very thin. Although pads can sometimes offset or change the sound of a headphone, to some extent you are stuck with the driver and housing. A less porous pad (e.g. leather, pleather, vinyl) generally will create a tighter seal and give you a bass boost, but often times it will also often boost the treble. Sorry to be vague, but I heard the T70 once for about a minute before putting them down, so I really can't help you aside from generalities.

    If you're looking for a a bassier headphone your best bet would be to find a different headphone :(. Sorry, probably not what you wanted to hear.

    Definitely not what I wanted to hear! I hear that all too frequently here! Isn't that the point of mods? If I just wanted to have two or three pairs of headphones I could buy the best on the market and never a change a thing with them, but where is the fun in that?

    Definitely understand your frustration. Hope I can elucidate. I'm no pro at modding, but I do know some very important parts to modding:


    1. Modding can improve the sound of a headphone. But usually it will only help the sound a bit. I.E. a headphone that does not sound good before mods will probably be plagued by similar issues after those mods.

    2. A mod can help one aspect of a headphone while making others sound worse. For example (in my experience) changing from the velour pads on the Hifiman HE-6 to the pleather ones made the bass much cleaner and punchier. However, it also made the treble much brighter which was difficult to listen to.


    With the T70, the treble is so far out of balance it would be hard to find any mod that will balance it out.


    Trust me I've purchased tons of headphones and swap them out all the time. I spent a few hours today comparing the Schiit Ragnorak and Mjolnir2. I love doing this stuff. But there are a lot of other headphones to try out and test.



    Edit: You may want to look into EQing them. Might yield some positive results.

    - 5dB centered at 9kHz is probably the first thing you should try.
    You can boost the bass a bit or pair them with an amplifier with relatively high output impedance.

    I haven't tried the T70p but it seems to be as bright as DT990, you need to pick matching recordings to make them shine.

    Personally, my favorite pads for the T70 are the stock pads off of my old Soundmagic HP100. The pads are pretty thin which helps to prevent sibilance, but they are also pleather which I find improves the bass response quite a bit. The thicker the pads on the T70 the more sibilant it's going to be from my experience. They're still not perfect though. I doubt the T70 ever will be.

    Here is a link to a passive filter designed for the t90. The link originated from diyaudioheaven, tons of DIY explained pretty well on there. The filter could help the treble peak, other mods might boost the bass if you still want more. After the treble is tamed though you may find the bass more satisfying

    Is it possible to build that filter in the ear cup?

    I have been trying to find the parts to build it, if everything is small enough you could put it in the cup. It would have to go in the left side where the wire enters. I would not recommend doing this though because it could cause changes in sound between R/L. Different volume of empty space inside sealed cup and obstructions that could cause echo with poor placement are couple of reasons I say that(I am no expert).

    I have a set of T90 that I was going to build this for. I was planning on building an adapter to simply into, T90 ==> Filter ==> Amp.

    Sort of like

    I tried my zmf pads(angled lambskin), not mounted properly just pressed on. They did not do the t90 any favors, seemed like it hollowed out the mids, upper treble emphasized, bass got boomy.

    The T70 will not sound thin and overly bright if you can have good pad seal when wearing. The material of the T70 stock pads also seal better and provide more isolation than the typical Beyer velour pads from DT770, T1, etc.

    The problem is the stock T70 pads are too shallow. If you have big or "Micky Mouse" like ears, I can guarantee there won't be a good seal.

    A simple mod you can try with the stock pads is to put a circle of cotton string under the inner edge of the stock pads, to make the stock pads protrude a little more, making the pad space a little deeper. I find 5mm thick cotton string works best. It costs close to nothing.

    the T5p (2nd gen) look like they should have potential, I am also going to test akg k55x pads once I get my t70p.$180 > cost = :D should be here in a week or so....

    I read somewhere that akg k240 pads worked well, got me wondering about q701 pads

    Threw the akg K551 pads on the T70p, sounds really nice. Brought more life to the low end, sub bass sounds very nice. I cant tell if it helped tame the treble spike or if it is just the increased bass but the sound is less fatiguing now. One issue that did arise is distortion in mid bass at mild volumes with certain tracks. This does not bother me much because I usually listen to music at lower volumes, but I will try to fix this with internal damping. I am guessing that the distortion is a result of the tight seal provided by the pads.

    Hi, I find most on ear portables Senns, AT, Vmoda to be overly bassy.
    I find The T70p to sound flatter than most. I think part of their treble spike "rep" is due to
    modern recordings and mastering being too loud, bright and compressed
    Listen to something well mastered eg DCC label and the T70p sound right and beautifully transparent, I use a HIFIMAN Hm901 with mine and I can't fault the sound. For my sins I am musician first, audiophile second so am super critical of replication of guitars and drums. I tried almost every closed on ear portable, Amperior, Momentum, Vmoda, PM3, ED8 and I thought and still think the T70p is most accurate.


    Or maybe my ears are just f*€ked!
