Hello, I recently bought a pair of used HD555. Today I have noticed a tiny puncture in the paper sheet covering the membrane, which looks like this(red line) :   As I am very OCD about my hardware, I took them apart once again to examine the celulose from the back side(as it turned...

I'm picking up a used pair of 555's and am considering doing the foam mod. My only question is why Sennheiser put a large piece of foam in the first place that does nothing but make it sound worse? Does the foam have some other purpose that just doesn't work right or something?

Here are photos of the state my HD555's are in.       They somehow cracked, and one of the cans is not connected to the headrest. Basically, it hangs by that thin cable in the photo, the cable that goes through the headphone. I have been using duct tape to tape the broken off...

It's a great headphone, but I need a closed phone for noisy surroundings (trains, computerpartys with 40" speakers 1 meter from my head etc). Also for not pesting people around me. It will mostly be used for movies and games. I like the sound of the HD555 very much, but would like a little...

Hi, I currently own a newer model of the HD555 and I've realized that it is 50 Ohms unlike the older models. Is there anything I can do (like an adaptor?) that can raise the impedance to the old specification of 120 or close? Thanks EDIT: it's 120, not 150 my mistake

I have the Sennheiser HD-555 which I had enjoyed much until recently when the left driver stopped... Initially I thought it was the cable and disassembled, ordered a new cable, installed new cable and nothing... so I now know it wasnt the cable and have an extra....   Short of selling my...

Just wondering to people who have hear both since these are both of the same price range how do they compare to each other,such as quality of the bass/lows,mids,highs and comfort and in your opinion which you like better and why.

I have owned and used my Sennheiser HD555 for many years now and I have been very pleased. Have used them mostly with my PC listening to all kinds of music genres and playing games. A couple months ago my pads started ripping in the seams so now i have started thinking about a pair of closed...

I was looking for an upgrade from the Hd555 and was wondering if the T50rp would satisfy me.

Currently using Sennheiser HD 555s stock (no mod) with the HT|Omega Claro Halo stock (no mod) sound card.  No speakers.  This setup powers mostly gaming and fast, BASSY music of many genres.  **Me likey the clean, deep bass.**  I do enjoy this setup, however, another full system upgrade is...

Hi all, new poster here :-)   Ive been using Sennheiser HD555's for about 2 years now, they are powered by my HTC Sensation to listen to FLAC audio files usually, however i would like a bit more volume, and hopefully greater bass response.   These are the only good headphones ive really...

I'm currently in a dilemma about what purchase I want to make next. I own 2 pairs of headphones currently, a pair of ATH-M50s and modded HD-555s. I mainly use them through a Xonar DX in my computer, for a wide range of music, movies, and video games.   I've decided that I want to either...

Hey guys, first time poster here but I've lurked for a while. I've been doing a lot of research on these two cans and I'm not sure which is the right decision. I'm coming from a HD-555 and I'm used to its amazing comfort and general sound signature. I'm usually alone when I listen and...

I recently went to PAX East last weekend in Boston, which was my first PAX event, and was blown away by some of the audio coming out of the different stations they had set up, which lead me to think, What am i doing? i have decent audio set up for portable music, PC music/movies, but nothing...

First post, apologies to mods if this is in the incorrect place, feel free to move it if so!   Hi all, just a newbie poking around trying to find some info :-)   Im looking at changing/upgrading my Sennheiser HD555's, purely for the reason they have stuffed my headphone jack on my...

My headphones are Sennheiser HD555 and my speakers are Logitech z506.   I game and watch movies, a lot more than I listen to music. I currently have an Asus P6T with onboard audio, Realtek® ALC1200. I also have a Creative SB Titanium HD to compare it with, and I noticed some obvious...

Hi, new to this forum :)   I'm currently using a HD 205-ii. Ok satisifed I guess, not an audiophile or anything like that, and have an amp (Fiio E5) and E3 LOD cable on the way from Amazon.   Anyway, I want to upgrade my headphones to something better, just to see what I'm missing, and...

Hello   I have just purchased a Sony d250, along with Sennheiser HD555 headphones. Im really curious to discover just how close the sound quality is when compared to a considerably more expensive mid range Naim system, which I used to have. Maybe spending a fortune on a conventional hi fi...

Hey guys,   Been reading through the forums and saw lots of good op-amp recommendations. One common recommendation is the LME49720HA. Would you recommend that for my Sennheiser HD 555's? I'm looking at upgrading to the HD 700's soon, if that makes a difference. And if that is a...

Hi there peeps. First off, I'm still very new to this improving the sound thing and could do with some advice. Right now I'm using sennheiser hd555 and a fiio e17 to play tunes from my iTunes in mostly lossless. Generally a bit if everything from rock to hip hop to classical to ambient to dance...

I'm looking for an upgrade to my Sennheiser HD555. I have an HT Omega Claro Sound Card (with built-in headphone amp, up to 600ohms of impedence) that will be driving the new cans. My early interests: •Sennheiser HD598 •Sennheiser HD650 •Ultrasone Pro 900 Music that I enjoy: dubstep, metal, rap...

So I stumbled upon this forum after spending years using avsforum as my "go to" source for audio and video products.  I am not sure if the members here know, but some members actually point people over here when they want to know a lot about headphones... so here I am!   I am on the quest...

Hi all! Long time browser, first time poster.     I've been using the HD428 I got for Christmas and I'm really enjoying them, but I'm looking to get some with an open design to complement my closed cans.     I listen to a wide variety of music, watch movies, and occasionally game on my...

First post!   I am currently considering rewiring my old HD 555s for multiple reasons, including the cable failing once in a while (short, I guess) and the cable itself being 1 zillion meter long (3m). I thought if I'm going to change the cable, might as well do it properly.   I have no...

Hello everyone,   I’m looking into getting a pair of premium headphones (first time!) to see just what I’ve been missing as a music lover, however I’m trying not to go over $300.  Currently I own an Ipod Touch (I’ll have to get an amp too of course) and currently most of my music is in Apple...
