    Official Groups feature?

    I did a search prior to starting this thread. While a couple of threads came up, they weren't in the right sub-forum.   Anyway, how about a Group feature?   There are quite a few fanclub and appreciation threads around and it'd be great if you could create a group and have the fanboys...

    Bye head-fi

    A couple of months ago I bought the HD438 headphone. I thought I should get an amplifier to complete the set - source > amp > headphones, but I bought the Sansa Clip+. Now this was an improvement over my PSP > HD438 but I soon fell in love with the Grado modding thread. The M50s were getting a...

    Foobar question!

    I've installed the WASAPI plugin.   Under output I've got these options       I hear sound through my headphones when it's on DS: Primary Sound Driver, DS: Headphones and WASAPI: Headphones.    In wasapi headphone mode, the music is much louder than in the DS modes at the...

    Clip+ internal amp and DAC vs Fiio E7

    Is it possible to.... [Sennheiser cable mod]

    Planning to recable my HD438 with other thicker cables from Sennheiser. The problem is the HD438 cable has a funny looking top end that connects to the headphones. So is it possible to get another headphone cable and modify that cable to fit into my HD438s?   And how much would something...

    Sennheiser HD4x8 Modification for newbies

    I've noticed a couple of people wanting to buy the HD418/428/438/448 these past few weeks, and after digging through several threads I've come to the conclusion that a lot of HD448 buyers were disappointed with the depressing (lol) amount of bass in their headphones.   So why did I create...

    Bass extension

    I just can't get my HD438s to hit sounds below 43-45Hz. The technical specs state that the HD438 can reproduce sounds as low as 18Hz, but using a signal generator, I couldn't make out anything below 43-45 Hz, at max volume.   I'm doing this test on my computer. Anyone has any solution...

    HE300 vs DT770 (headphone upgrade)

    I'm looking for possibilities on a new headphone upgrade, which won't be any time soon since I'm saving up for other things as well. Any one of these will be a huge step up from my current HD438, which I'm actually quite content with..   I listen to songs such as Shadowplay , All These...

    Connecting amp and laptop

    So I realised that my laptop doesn't have a line out, and I'm forced to connect through the headphones jack. But is the sound quality is the same by connecting through the black ring, or is it better through line out.

    Just a thought ..

    Assuming I have very good crafting skills,    Can I pick apart a pair of closed Senns cans, punch some holes in the outer shell of the cups to make it "open-air" headphones?      like this

    Q: Source - amp - resistance adapter - cans

    The primary purpose of a resistance adapter is to increase the impedance of the cans, yes?   I am currently looking to amp my Sennheiser HD438s with the PA2V2. The HD438s have a low 32ohm impedance. Will adding a resistance adapter to increase the impedance of the headphones improve the...

    PSP too muddy, to amp or not to amp?

    I use my PSP as my portable music player, and I use Sennheiser HD438s. The sound coming from my PSP is very different from the sound coming from my laptop. The PSP makes the music sound so squashed and muddled, while the music from the laptop is clearer and has more separation.   Will...

    How to test the noise level in my headphones?

    I've heard that using an amplifier will increase the noise level that is already there in my portable set-up, so I'm thinking of testing my headphones/source to see if the noise level or hissing is already horrible, before buying the amp. So how do I do this? Search came up with nothing...

    PA2V2 Portable Amp, comments?

    I understand that these amps are hand-made by a Gary Ali and I've been to his site. Apparently best way to contact him is through e-mail but I don't want to waste his time with some questions that might seem trivial..   So first of all, are they still being produced?   I'm using a...

    Books - Headphones?

    I think this is the most appropriate section. I've been looking through the results in the search engines but most of the topics are already stale, and there are even less topics regarding books on headphones.   Does anyone have any recommendation for books to read to up my knowledge on...

    Modding my Sennheiser HD438?

    Hi everyone. I was wondering if anyone knows of a way to remove the Chrome spokes, spraypaint them and them put them back on? Also, is there a way to mod the headphones to make it sound better?  I probably shouldn't have made a new thread just for this but I didn't want to hijack/necro...
