I have the problem with fuzzy volume on the Ultra-Micro and I use the "wiping the volume knob backwards and forwards" workaround. However as time goes by the problem gets worse, and the amount of time between me having to do it decreases. Surely doing this every day must be a massive source of...

I want to speak with a Sennheiser rep via PM. I have tried once but got no reply. If you are available to answer my query, please show yourselves...   Best Wishes   Noparanoia (currently experiencing Moreparanoia with every passing minute)  

Chasing a 5 year old (decent-ish condition) pair of HD650s which have light use (around 800 hrs aprtly.) I like the sound sig of these oldies. But how much is a pair this old actually worth? With 1hr left they seem awfully pricey for their age.   Thanks

My thread about my wonky HD650s (1 new, 1 old driver) died. Seems most of you guys arn't that big on helping noobs so here is something that might actually be of interest to you.   A couple of hours ago I cranked up Sinegen to try a sweep of frequencies on my HD650s, and guess what? Tracking...

So the left driver on my 4-5 yr old HD650s died, and to my bemusement they came back from Senn's UK repair centre with a new type driver in the left can. This is despite me raising my concern that they would sound unbalanced. (Which may of course mean that my concern was unfounded) Anyhow...

The other day I broke my HD650s, the left channel cut out while I was listening. For a small period of time my Ultra Micro stack was playing through just one channel. Can this damage the amp (or the remaining working driver)? Thanks

The left channel just cut out on my 4 year old HD650s. Sennheiser says their flat rate for repairs is £40, which is fantastic considering buying a new capsule will cost £50. I'm very nervous about the idea of sending these off. For one thing I keep hearing people here talking about "old" and...

I have HD650 which I use without the foam pads. As a result of this dust (could be dead skin) and the occasional hair get stuck to the clear membrane around the driver. Does this risk damaging the phones or decrease sound quality? 

I have Ultra-Micro stack with standard power bricks. I am wondering about the Astrodynes. Both their effect and the extent of said effect. The main thing I am interested in is if they will make the music sound more "powerfull". Not in any particular range (I love the balance of my HD650s...

...that their enjoyment of listening to music is severely diminished by dodgy hearing?   Obviously everything is relative, occasionally my hearing is fine and listening to music is very enjoyable. The rest of the time every tube in my head seems to be full of mucus and my music sounds like...

Obviously everything wears out eventually, so I don't need anyone to point that out to me :)   I listen to my HD650's, at a conservative estimate, for an average of about 10 hours every week. I have owned them for almost 4 years now (purchased them August 2006).   Am I Iikely to be...

Just recently Ultra Micro has started to become very hot, much quicker than usual. Not quite uncomfortable to the touch, but not far away. I also use the Ultra Micro DAC which never gets as hot, which I believe is normal for that unit. Now I can't remember if this development coincided with me...

I have been trying for ages to get my new PC to output audio that is as close as perfect as possible (e.g good enough not to be capping the SQ of my expensive Headroom kit). I use optical out, I have tried messing around with ASIO4ALL, Wasapi, Drivers all sorts of stuff but it still sounds dead...

My Ultra Micro amp has started to make static noise in the right channel when the volume is adjusted. I dont remember it ever doing this until very recently (I have had it for about a year now). It is not a problem in and of itself (it doesn't bother me) but I would like to clear up that it is...

Hi, To cut a very long story short(er); a few months ago I had a new pc built. I can upload specs if anyone wants them. It has a cheap Realtek built in sound card and runs on an evaluation copy of windows 7. I used the optical out with my Ultra Micro DAC, but I noticed that the sound wasnt as...

Hi. This is my first thread, so be kind. I have just acquired a new PC: Gigabyte GA-EX58-UD5 motherboard, i7920, 6gb DDR3 RAM. I was previously listening to my Headroom Ultra Micro Amp & DAC driven HD650s through the optical digital out of my old pc's onboard sound card. The listening...
