eh...Zen Micro Photo? I don't quite trust Creative's QC, though.
-
Agree with LaoMao...I find Sennheisers having a comfortable feeling, laid back music. Other than that, I wouldn't say it has any specialities.
-
You get it from LHS, right?
-
Erm...I hope I don't sound silly, but how do you put the tubing on the soldering points? I mean, is it you place the tubing unto the wire, solder the wire to the point, then just push the tubing into place? And also, do they help alot?
-
Sorry, just making an example...know nuts about batteries... Just asking then...will this affect the circuit in any way? I mean, beside providing the ability to swap with power-hungry opamps... So basically, I can swap the 9v with 2 AA 4.5v rechargeables? Also how long typically does this last?
-
Don't know if this has been asked before, please forgive my repeat then. Does rechargeable 9v's last longer (as in maintain proper operation of cmoy2) than non-rechargeables? Also, is there any other combination of batteries that would last longer than either of these 2? (Like 3 X 3v?)

Looking for cheap/good value headphones for noisy

Suhre E2c/g...great isolation, decent sound. -
Hd 280 Pro? With your amp, I don't think think the 64ohm impedance is a problem. Overall a decent can, with some nice bass after burn-in. It's closed though, so sweaty ears might be a problem.
-
Question about the battery...how does one recharge it? Or rather, is it compatible with the normal GP 9v battery recharger? Else how?
-
When did you buy it? The md33 burn-in after a few months or so of use, though I've only noticed a tighter, deeper, bass.
-
Lol. Disregard, the main mix volume of my 0404 was just too high. Kudos to grado details!
-
I went on vacation for a day or so, and so happens my brother uses my sr80 to play call of duty 2, if any of you know what that is. So I was listening to a jamie cullum cd, and I heard distinct crackling at certain tones.... I hope for the best....
-
Ermm...the hd 280 pro senns did quite well for me when I was on a plan. It doesn't cut out the noise totally...but it's decent enough. Just that you have to equalise pressure in the ears more often (and people were wondering why I was 'yawning' so much...)
-
Well...fyi, Hung Bro has them going at about 75+? Around that range. Oops! Forgot, no discussions here. Deep apologies moderator!
-
It isn't in-ear is it? Perhaps the bass needs some burn-in, like the sharps.
-
Actually, you can find flux cleaner. It's rather common in SLS. I found FLU fluxcleaner from Electrolube at Sunlight electronics next to Kaishin (or is it? Can't remember). Anyways, you spray this unto the board and wait a few seconds, observing that the flux gets dissolved. Then take a wet sponger and wipe. Repeat if necessery. I think the method should work with normal alcohol, no?
-
Wow...interesting, but quality?
-
Lol, first time trying out some beyers. Tried a few, and from what I can tell, it provides a really nice wide soundstange. And of course, soft comfy pads
-
Lots of high end stuff, is what I can say. Overall an excellent meet.
-
Eh? I was of the opinion that all alkaline rechargables need to be fully discharged, and that the only batteries without memory effect is that of Li-ion batts...Ah well, rusty memory Can you troubleshoot the board? Hmm...my poly's just starting, so I won't be as free. Hmmm...PM me when's conveniant for you to help, and I'll see if I'm free too. Thanks, anyways
-
Wow, 6 -7v, and it's dead? Hmm...that what kind of batteries does one use? Nimh rechargables require a full discharge before going to charge, right?
-
Yeah, it's alkaline, or at least I think it should be. Why? Need to go borrow a good camera to take. Erm...nevermind about the drilling, take it one step at a time and just get the darn thing to work.
-
Hmmm, thanks koss, at least now I know it's not that it's fried or something. Ok, will stick to opa2132. Checked with a multimeter, voltage of the 9v is still quite high, around 7 - 8, so I don't think it's the battery. Is there a possibility that I might have burned the pot? Perhaps I heated the pad or the legs for too long. Also, might a dirty IC socket have any impact? In which case, how could I clean it?
-
Lol, sounds rather huge for headphone. Maybe you should go speakers first? Don't forget, you have to design the circuits and drivers in such a way that it can fit your head, and still get the sound you want. Some proffessional help, me thinks you might need.

1. After testing, I jumped for joy Then I tried changing opamps. Opamps I used : 2228AP, 2227AP, and 2132AP. Also, LM6171 and LM6181 for the ground opamp. Gain setting is as first page, no change of resistor values. Source: Zen Micro Output: Generic earphones Battery: 9v Sony dry. Connecting wires: Multi-strand thin copper (the ones you can find on a normal stereo cable) Solder: 60/40 Flux Cleaner: Electrolube's FLU Soldering iron: Antex spade tip Pot: Green Alps, as of first page Will try to take, but I don't exactly have a digital camera on hand at home.
