i dropped my sr225's now only one side works, all wires are still soldered! What could i have done now....?

Possibly displaced or busted up a driver.

 

[kamal007]

is it still under warranty?

 

[Timmy029]

x2. but that fall should have been high to cause such damage. good luck bro, try sending them back to grado for replacement or repair.

im in the uk..will cost more to ship it there get it repaired and ship it back than it would for a new pair

, totally gutted, i mean.. im a student! took enough to buy the original ones seem's grados are expensive in the uk

if you can't get them repaired, theres always the FS section!

It's probably just a connection that came loose. If it were a driver, then you'd probably get a rattle or intermittent sound out of it.

Since you're a poor student, you might want to beg for help in the DIY Forum. One of the recablers might take mercy and offer to resolder them for free. I'd help, but I've never opened a pair before and would not want to ruin them. But I know others have, and they might be willing to do it.

Larry at Headphile (http://www.headphile.com) might also be interested?

You need to try and determine if its a cable wire or a damaged driver.

To check the wire: You'll need a digital multi meter and a segment of solid core ~20 AWG wire to trouble shoot them. If your meter has alligator clips, use those it makes it a lot easier IMHO.

Use the segment of wire, and poke it carefully through the exterior earcup mesh-grille and touch the driver solder pad with it. Be careful NOT to push it through the driver housing and into the driver. Now use the exposed wire as a test point, grab your multi-meter and check for continuity at the TRS connector.

If your wire checks out OK, then unfortunately you have a cooked driver. You can also use this wire-method to ohm out the driver resistance. Grab a pair of wires, and insert them through the mesh and touch them against the solder pads. Use the wires as test points and take a resistance measurement across the drivers. They should be around 32 ohms. If you're getting a reading in Meg-Ohms, then the driver is cooked.

There is a remote possibility that you cracked the solder-joint on the driver. Use the hair dryer/spoon-pry method to soften the hot melt glue and pull apart the earcups and expose the solder joints. Quickly, touch the solder pads with a ~25 watt iron. Heat the pads just long enough to get the solder to flow. You DONT want to hold the iron on there any longer than that, or you'll run the risk of melting the lead-wire... and make the problem worse.

If all that fails, you're only hope is to return them to Grado for repair.

Good Luck!!

thanks guys, i'll have a look at a few things youve suggested, failing that..... i'll put the parts on the fs forum

 

[Timmy029]

well no current running through them... so god knows what ive done... i want to post the right driver on for sale for spares or repair but cant...., says i dont have the privelages so i might just have to ebay it aswell as the headband etc

Thanks for your help guys just have to start saving for some new headphones.....

 

[RedLeader]

You have to have 50 posts to make a for sale thread, fyi. So you tried what kramer suggested?

 

[Timmy029]

yeah its just registering no current between the two solder points, im going to assume i cracked or broke the voice coil or something..., i'll just wait till i get 50 post and put them up for sale for spares or repair.... more expensive to have them repaired than just sell the bits off and buy a new pair of cans.. atleast i get the fun of looking what new headphones to buy and testing them

, but overall im gutted.... lot of money to waste

how much you think i should sell the right driver for and the headband?

Good Luck with the sales.... One thing to be careful of, is the plastic "C" hanger can crack if you spread it open too far. So use caution, when you pull out the driver housings.

Did you check for continuity between the solder pad and TRS connector? Till you do that, you won't know if its just a cable or the driver too.
