Try building a headphone amp with an LM-386.

Preferably LM386-N1 as that is only 325mW and won't blow your headphones to bits. But it might be too quiet :? I haven't tried yet, too busy with other stuff. Take a look at www.runoffgroove.com, the little gem amplifiers are what I based my headphone amp *schemmo* on.

:D

it won't be too quiet. it would actually take your ears offf if you max it out. unless you are already deaf.. lol

actually a dual opamp has been used on a couple of different schemes to drive a small pair of headphones

hmm that's odd. My philips headphones are rated at 0.5W. :? And the 386 had a hard time getting loud sounds. At least not as loud as I like :mrgreeen: which is definately too loud :mrgreen:

JimBob:

I went through this back in December.  There's a project from HeadWize using a LM386 (actually, it uses two if you follow the design).  B Tremblay of Runoffgroove modified this design to just work from one LM386.  Check my build report in Reviews, and do a search here for "headphone AND LM386".  That should pull the references you need.  This is what I'm going to use for testing effects.
