I don't know... The click wasn't inside the DAC when it happened, but it was more like where the actual RCA connection is. It seems like there are some (metal? leafy?) parts in the connector part, that might touch the RCA male plug. Anyone know about this?

hd650 pretending to be hd800.....angled drivers tongue_smile.gif

Did you actually tried this ? blink.gif

post #11734 of 26752
Yup...the soundstage moved slightly forward, go try it out.tongue.gif
The foam is from an aircon doorstrip.

Lately I've been wondering why no one has ever made angled pads for the HD6x0. If you hold the drivers at an angle you can get an idea of how it sounds. Seems like there's a lot of potential there to make the soundstage wider and more realistic sounding and to improve positioning.

Interesting...just tried the angle to see for myself. It does make a difference. And I think that the sound stage does seem wider.

So... how much volume does it take to destroy a pair of HD-650's? I accidentally plugged it into the headphone out of my motherboard onboard audio (to compare with my standalone DAC) without checking the audio levels, and it ended up blasting away. The volume level was certainly enough to damage my hearing (if I were to listen to it at the volume for a long period of time)...

If it was briefly I doubt it'll hurt your HD 650s.  You'd likely sooner hurt your ears first.  Sound pressure level of the cans is rated at 103 dB according to Sennheiser... so it's roughly the around the range of a lawn mower or snowmobile I believe?

I found my best portable setup last yaer....

both of the cables were made by an audiophile friend of mine... 

the cable for the 650 is PcWork Symphonica 

while mini to mini (the blue one) is Legato-S

and amazed with GoVibe Vestamp...

 

I can fit everything in a casing and carry wherever i go :D

The 650's are likely ok. If you have a blown driver you be able to hear it. Your hearing is a different matter. Did you have them on when you blasted them? I got a blast from a set of IEM's about three months ago with a dap on maximum volume. My hearing has still not recovered. redface.gif

joe: Ah. Thanks for letting me know. The reference to the landmower/snowmobile is especially helpful. I actually googled it to double check, and it seems you are right: http://www.gcaudio.com/resources/howtos/loudness.html, with the snowmobile/motorcycle at 100db, while a powermower is at 107db. And, the Sennheiser website lists the HD-650 SPL, at 102db, indeed as well. Thanks again for letting me know. And thank God my HD-650's are ok. Now I REALLY know they're ok. 

 

matt: Ouch. Hope your hearing is alright. I did have them on for a second, and while I do notice a tiny, tiny bit of ringing in my ears, I'm not sure if that was because of the incident, or if it's a case of tinnitus that I've always had. 

 

coolerthings: That's a sweet set-up man! Everything there looks sweet: the headphones, the cables, and the amp. 

post #11742 of 26752

Just reading about headphones blasting your ears at max volume, even for a split second, is making my ears hurt... ouch.

post #11743 of 26752

Can these still sound good with a portable amp?

post #11744 of 26752

^^^Yes. Ive used it many times with my Arrow 4g, not quite as good as my fullsize setup but still good.

I'd recommend the Neco Soundlab V3. Really good w/ the HD650. I liked the SR71A quite a bit, too.
