Wow that is bad. Better stop talking to save what reputation you have left. You do know that an NMR uses its small focused field to scan the body a bit at a time, hence it takes so long? Regarding the topic, all nonsense, of course, and everything that isn't in this thread, may be measurable...

no, it's normal. The 5pro are too sensitive for the ipod, so use the attenuator.

Those are very unlike mine. The transformator looks strange.

Use the airline adapter for added impedance, the noise will go away. And I wouldn't call it a veil. I think the 5 pros are just unspectacular headphones. If you buy shures (e3 especially), the vocals are very prominent. Jazz is very sweet with them. Yet - is it a feature or a flaw? On the...

K340 with velour pads.

Humidity and heat are never good for electronics, in the long run.

Don't worry, K340s pop up on ebay now and then. I saw a NOS K340 on ebay US a few weeks ago, but it was a bit pricey (300$?). I would not primarily think of soundstage when buying phones though. IMO it's a very elusive quality and frequency response is more important in determining the...

You do not have to mod the K340 in any way at all. Well, possibly excepting changing the earpads, there are velour ones that are a lot more comfortable than the standard leather earpads. Apart from that, it sounds just fine stock. IMO it's not very hard to amp either. You may get better sound...

It's not as easy as that. The Senn 650 will probably not be a bad choice, if you go for fullsize phones. IEM's have a hard time matching similarly priced fullsize cans. Beyond that you will have to listen to them and then you will know if it was the right phone, no earlier than that.

It's not even about the bass, or the cable, it's the treble. The uber piercing evil treble. DO NOT GET THOSE PHONES. The Senn mx500 blow them out of the water.

Nothing is used to drive them. They are PASSIVE. Like in a passive radiator subwoofer

EDIT: the electret is the big metal thing in the middle, those are just passive diaphragms to tweak the frequency response or something.

The K340 uses 1, not 6 electrets, a big one mounted in the middle. Crossover is mechanic with the dynamic driver mounted behind a panel and 5 small passive diaphragms linking it to the main chamber with the electret.

Personally I find the sq of the plantronics 90 disappointing. The only reason I stick with plantronics and don't use my K340 is that the p 60 is a lot less hot than a circumaural phone. Almost everything recommended here will be a lot better than those. Of course, for gaming, it's...
