@steinmb ooh, nice to see a response from you. I've been reading your guide very carefully the last few days. I bought some abs cement from my local hardware store and am going to try that first before tackling the more complex-looking epoxy and fiberglass procedure in your write up. thanks...

For posterity: Shure's parts department is lame.   I tried to order a replacement part for the my 840's (crappy plastic that connects right ear phone to the head band and that breaks for everyone) and got no love from Shure's parts department. They insisted that I send the headphones in for...

To follow up for posterity, Audio Technica sent me a free replacement arm.   I couldn't be more impressed with AT USA's service department. I emailed them in the morning, inquiring about purchasing a new arm, received a reply within an hour offering the part for free, and ultimately received...

Thanks to Pingupenguins for the excellent, comprehensive write up and pics. I just picked up a dirt cheap set of broken m50s so this guide will be super useful as I try to revive them.   Random question: does audio technica sell the arm assembly that holds the cup?   The set I bought is...

Not to thread necro, but I just wanted to thank steinmb for the write up and pics. I'm thinking about buying a cheap set of damaged shure 840s and giving this repair a try.     Quote:

Not to thread necro, but in case any future people stumble across this thread, I put together a youtube video on how to replace the HD580 grilles with the HD600 grilles: http://youtu.be/5cZKFZ7PKoo

Had to remove my 'how to' video because of a copyright claim on the music I used, here's the re-uploaded vid:   http://www.youtube.com/watch?v=_b53VDWA10k

Re: Beats If the OP must have beats, monster is currently (as of 4/29) having a sale on refurbs with an extra 15% off from techbargains. Pro's seem to net out at $212.45 (free ship, tax in CA), so Studios would probably be in the same...

Thanks to all who posted about ordering via telephone from Sennheiser.   I just ordered HD 600 grills this morning with a telephone representative, so it looks like they're still in stock as of April 27.   And FYI, I was quoted around $32, including shipping and tax. As the earlier...

Not to thread necro, but personally, I profoundly dislike the Z-2300's, but have never heard your other 2 options. Given my experiences, I'd say go with anything except the z-2300's.   I wholeheartedly agree with the earlier reviewer who called the z-2300's 'fart cannons.' To my...

Thanks very much for the write up, it has made my 580's feel young and alive again.   I took the liberty of making a Youtube video of the process, with credit to you for the original write up. I also substituted memory foam (visco elastic) for the open cell foam you used.   I've been...
