Did you manage to disassemble your T5p?
Did you manage to disassemble your T5p?
Yes! It was easy. Once the cushions are removed there is a little corner around the driver cover where you can place a small flat screwdriver and then pop out the driver. I found out that it is easier to leave the cushions on the rings and pop off the cushion-ring with the cushion sitting on it. In that way there will be no scratches at all after disassembling them.
Also assembling it again is easy as the driver pops right back in again. It doesn't even leave any marks. Now I just have to find the right cable and mini-jack plug. I also think I will get a cable a little longer than the stock cable.
Beyerdynamic T5p Impressions:
What a great description and review of the T5p. I am sure that getting used to the bass is crucial when listening to new headphones. You should give them two-three weeks before finally deciding if you need to mod them for more bass. The worst thing that could happen is that you after a while will dislike all your other headphones because they now have too much bass and are too dark sounding once you get used to how (I think) headphones should sound.
Congratulations with the T5p - enjoy the music! 
GREAT post.
Lots to respond to there, not got time now, but a few thoughts:
Removable cables - YES! This is really a must and makes transportation for portable use easier. A significant failing for these headphones, and all other high-end headphones without them.
Carrying solutions - yours should have come with the metal box if they are new... You are correct though that the metal box is useless for portable use. For me another failing for the portable use-case scenario that these were purpose-built for, and rather inexcusable for the asking price here.
Comfort - agreed, these are extremely comfortable headphones. The cost there is that isolation suffers a bit, as you mention, given the decreased clamping force and cushy pads. Sound leakage doesn't seem too bad, I found them comparable to my Ed8 in that regard (my brother A/B'd both and I listened for how much I could hear, no discernible difference for me). After experiencing my HD25, which I could only wear about 15minutes at a stretch before getting headaches and extreme discomfort, I'll take the comfort overall, but it would be nice to have it all.
Glad you're the enjoying guitars on these, being for me one of the most important things and something the T5p really gets right. Quite a relief to hear you say that! This is such a subjective hobby, and whenever someone takes on board things I have said in making a purchase decision (particularly a substantial purchase like this) I always feel a bit anxious that their subjective sense of it may be different.
Regarding the bass - would echo your sentiments. Always found the quantity lacking (although it doesn't bother me near as much as it seems to you, I only EQ it lightly and I'm perfectly happy), but the quality excellent. For me the bass quantity mostly manifests in stuff like Massive Attack, an example you also mentioned. Certainly giving it some more time to acclimatise will help a bit, as going from LCD-2 to T5p will certainly make the transition in bass sound more than a little rough (I can personally relate to that, also having the LCD2s). In relation to drums specifically I don't have any particular problems, I certainly find them to have enough punch, which for me is an important quality as it is for you. When my brother, a drummer, A/B'd these and the Ed8 he remarked that he actually liked the drums more from the T5p. That makes me wonder whether I have gotten a bit lucky in upstream pairings with the T5p, as my portable DAC/amps for the most part are quite forward and punchy (HeadAmp Pico and Apex Glacier being the ones I really like with the T5p, especially the Pico which seems to impart some oomph and warmth to the bass). Would be interested to see how different you find them if you alter the pads. At some point soon I will probably have a look at swapping the Jaben pads over to the regular T5p I have. Be interesting to see how much difference the pads make on their own when the balanced cables are taken out of the equation.
Definitely agree a bit more bass presence and impact would have made these nigh on perfect for listening, a slam dunk as you say. Add a bit more thought into design aspects for portability (including a good carry case, removable cables) and I don't think any other closed cans could touch them for me. So, Beyerdynamic, if you're out there: you know what you need to do now - go forth and make a successor to the T5p with these qualities. I for one, would snap them up in a heartbeat.
Thanks for posting your impressions Theogenes. I might the be the only person satisfied with the bass on the T5p, I use the headphone almost exclusively for acoustic recordings. I also love that felt zipper bag that I didn't get with my T5p, I got a hulking great aluminium box! If anybody would like the box I'll gladly exchange it for the felt bag.

Thank you for your kind words!! And yes sir, I definitely plan on keeping these bad boys for at least a few weeks, and hopefully a lot longer than that... I know Tyll really slammed these cans, and I greatly respect his knowledge and opinion, but I wonder if there isn't a problem with QC at Beyer or something that causes these vast differences in opinion on the T5p... because I really, really like them, with the major caveat about the bass noted.
I actually have my dad listening to them from his phone right now (he's in town to help me with another matter), and he is most definitely not an audiophile-- but even he has just sat there, blissed out, listening to music. I even caught him singing softly to himself, and this is what most people would consider a very gruff, burly man. Such is the power of truly great gear to connect us all to the music, I guess!
Here's to you, fellow T5p lovers!!!

It sounds like we are on pretty much the exact same wavelength here... Now we just need to get Beyer in the game!! They need to sic some of those Germanic geniuses on this and see if they can give us a T6p with improved bass, detachable cables, and more appropriate peripherals while keeping all the things that make these so amazing. And if they can bring it to market under $1k... I just don't think they'll have any real competition. As rapidly as the headphone market has expanded in the last few years, this is still a fairly gaping hole in the lineup of potential niches.
By the way, one other thing I would have liked would be a collapseable headband. Not a dealbreaker, but given the size of these bad boys, it would definitely help out a lot.

I would be very hesitant to increase bass response, I feel it is excellent for acoustic/orchestral/classical etc, this is the primary use for me. I pair the T5p with the DT1350 to cover music not as well suited to the T5p. I was also not prefer not to have a removable via plugs etc, only because I found every additional connection removes a slight degree of transparency. With a single connection there are two solder joints and one physical connection to send a signal through. I am seriously considering installing an aftermarket cable on my set of T5p, I'm just unsure which one, how to go about doing it and the costs involved.

I can understand your point of view, and I think you are more specifically the type of listener that beyerdynamic had in mind with the T5p. With your musical tastes, I bet you LOVE these bad boys ;). That might mean that instead of replacing the T5p in the lineup, they come up with an alternative that better suits the needs of apparently bass-loving nuts like myself and others-- something akin to what Ultrasone did with the Sig Pros and the Sig DJs.
Speaking of which, I'd be interested to see any comparisons of the sales numbers of some of these headsets, if anyone is aware of a resource to locate them. (I somehow doubt it, but it's worth a shot).
Btw, listening to Black Sabbath's 'War Pigs' right now, and again, man, that tone.... it's just GREAT!!!!!!!
Theogenes,
I add T70/T70's micro velour pads to the list.
Those are nice pads for those who like velour touch, sound is good, but tad sounds like T70s.
And official velour pads for T1(EDT990VB) won't make sense for T5p because those are made for open back headphones (T1, DT990, DT880),
and will result significant reduction of amount of bass.
EDT770 series (EDT770S, EDT770V, EDT770VB) for closed back headphones are nice match for T5p.

Considering that headphones such as the LCD-2 and HE-6 use removable cables, I'm relatively unconvinced that the addition of removable cables is synonymous with introducing deficiencies into the sound. For a headphone that is purpose-built for portability I think the point is a slightly moot, even if a small degree of transparency is lost that isn't the end of the world in a headphone whose intended use-case scenarios include on-the-go listening.
I'm not sure I've explained what I mean by 'increasing the bass response' very clearly. When I'm talking about increasing the bass response I'm not talking about introducing colouration; I'm not a bass head. I'm talking only about reproducing the bass that is there, so that when there is more bass in the song you hear that. The T5p isn't always able to do that outside the kinds of genres you mention. I don't think having bass that is good in those genres and bass that is also sufficient for other genres are mutually exclusive qualities in headphones, or at least my HE-6, GS1000i and the HD800 I have loan at the moment don't suggest that to me. Perhaps a mechanism for dialling in the bass level ala the Tiesto is the way to go?
Actually: No. There's at least a second one ;-)
Maybe unusual for this kind of headphone I mainly listen to EDM (at least when using headphones) but nevertheless I consider them to have an absolutely satisfying bass response: deep, detailed and not overwhelming.
Thanks for the heads-up, beyerlove!! I'm going to try to get a quick list of compatible earpads for the T5p together (unless somebody else already has, which would be great) as a starting point.
[Addendum to Post #536 above]
3a). Compatible beyerdynamic earpads for T5p: EDT5p, EDT990 series (made for open-back cans, will probably reduce bass output and isolation), EDT770 series, T70p pads in micro velour (part number 910945, couldn't find a SKU) and nubuck leather (70NL EDT).
Also, I heard back from Wilson at Jaben, and he said they don't change the pads on the T5p during the modifications... Perhaps they did at one point? I don't have pricing for the modification to an existing headset yet, but as soon as I have that I'll post back.
And I have to say, the longer I have the T5p, the less objectionable I find the bass... Although as soon as I get in a mood to listen to something really groovy and bassy like Massive Attack, Puscifer, Portishead, etc I still do wish for a bit more oomph. I don't think I'll ever get to the point of finding the bass as it is fully sufficient, but it seems to me to be less of a deal-breaker than it did at first. Thank god for brain burn-in, I guess
