Hi folks.
 I'm totally gutted. My 7 year old K271's mk1 have started rattling, it's the left speaker only, and only when playing bass sounds even at low volume.
 I have checked for any hair stuck in speaker and there is non. The cable is in very bad condition but I've got a feeling that replacing it won't help. But, I don't know anything about these things so maybe it would help, what do you think.
 
 If they can't be fixed what would be a good upgrade? I would like something of the same or better quality sound, even it I have to pay a bit more. I would even get another set of these k271's if I could find the mk1's.
 I use my headphones for mixing and production. I have a 1977 Technics SU-7300 amp and a 600ohm headphone socket on  my motherboard.
 
Do AKG sell the drivers? So I could just replace the broken one.

This could just as well be a cable problem. The cable is detachable, so easy to change. Try it before you go out to buy another one or replace drivers. Or it could be a connection to the driver that doesn't have enough contact anymore. Plenty of things to check before you dismiss the HP

Unfortunately I don't have another lead/cable to try. I don't think they came with 2 cables. I have just finished putting the left side back together after having a look inside. Hope I don't have to do that to often as I found it really difficult to get back together. Everything looked ok in there.
 You reply is encouraging, I would love to be able to keep using them. If I can find somewhere to buy a driver I won't mind buying a new cable to try first, and if it doesn't work then I can buy the driver and I haven't wasted money on the cable.
 I'm still looking for a driver but so far I have only found a driver for the K240.

What are the chances that I have blown the driver after plugging it into the 600ohm jack? (and possibly turning it up to much)

 

[Teska]

Wouldn 't know how the 600 ohm output would effect a 55 ohm headphone. Where do you live ? The K271 cable is available seperatly. Just look for online shops.

Thanks for reply's  Teska. I've found a company that supplies spares. I've ordered a cable, and they have drivers if I need them. The drivers are cheep too. Only £11. If I do have to replace the driver would it be best to buy two and replace them both or would it be ok to just replace one?

 

[Teska]

Wel, since I read about headphone "burn-in" on this forum it will probably be best to change both cause the used one could have a different sound then the new one.

Yeah I think that's got to be the best way. I have ordered two drivers. If the cable which arrives on Friday fixes the problem then at least I have got a couple of spare drivers for the future. I've found drivers for the old k240DF 600ohm, now I'm thinking about putting them in the k271. It will be a interesting experiment.

Well the cable has made some difference. Things are much better now. But they still have a bit of rattle. So I have taken them apart and changed the drivers. I'm just waiting to get some solder this afternoon. I'm not looking forward to doing this as I know nothing about soldering. I know I will have to prep the surface of the copper I will be soldering the wire to but I just hope that the old wires don't need any prepping (like the old solder cleaning off) and can just go straight back on.

 

[Teska]

Watch out there, course the drivers' wires are realy thin and should be soldered with extreme care.

Hi there, can you please tell me who the company is where you bought the drivers?
 
Thank you,

Got the same problem with only left ear driver. Pretty sure that cable is not the problem.
