No, I'm not selling mine (they're not resallable, being custom molded ).

But I've been in touch with Jerry Harvey at UE to find out exactly what SPLs (Sound Pressure Levels) UE-10 Pro emit when used with a DAP.

Now, he will be conducting tests with a dummy head and proper equipment to do this, but he's got an iPod as source. With its 30 mW per channel @ 32ohms it seem to be the same as the Karma in that department.

However, if somebody owns a Karma and is interested in knowing exactly what volume it would output when combined with UE-10 (not knowing how the volume steps are setup in Karma is an example of how iPod might differ), Jerry needs a Karma in his office by next Thursday. He will then send it back the next day.

I would do it myself, but I'm based in Italy and it would be pretty tough. If somebody is willing to do this, I will be readily available to repay him shipping costs through PayPal.

PS
Sorry for crossposting this from Headphones, but if I am to find a solution for this I am to find it fast... I hope nobody will get upset.

I was planning to order one from amazon next wednesday or so. If Jerry would order it and have it sent to himself, I could then buy it from him. Just a thought.

With IEM, canalphones... you have the potential to:

a) Protect your hearing, because being isolated from outside sound means you can listen to lower levels.

b) Damage your hearing, because the isolation level tempts you to raise the volume a little bit, to get more details or just because you lke it a little louder. And it's easier than with open cans to reach dangerous levels.

With MP3gain you can analyze an MP3 to know how loud it sounds on average. I would like to know, for instance, what SPLs the UE-10 coupled with the Karma reach on an 89dB song, at any given volume setting.

Because I want to understand what's a safe volume to listen to on my Karma. I like music loud and clear, but I do not want to damage my ears.

For instance:

Recommended maximum allowable exposure times (by Nova Scotia Department of Labour) are:

16 hours for 80 dBA sound
8 hours for 85 dBA sound
4 hours for 90 dBA sound
2 hours for 95 dBA sound
1 hour for 100 dBA sound
30 min for 105 dBA sound
15 min for 110 dBA sound
7.5 min for 115 dBA sound
0 min for above 115 dBA sound (there should
be no exposure at
this level!)

I just wanted to inform everybody interested in Ultimate Ears that, hopefully by tomorrow, I will be able to provide detailed SPLs information about UE-10 and UE-5c when used with iPod and Karma.

Many, many, many thanks to cmascatello for trusting me in this. Everything went smoothly.

I believe this will be interesting information, as I have read of several users that intend to listen for many hours a day to their UE.
