Ahh, I do know that the alkalines are much better. In my situation I'm going to get a few nimh cells 9v sized soon for portable amp use. The choice I made was when I took the photo, and didn't have enough money (3ish dollars) and had to get the crap battery, cos I needed it then Being a student and not having a job means I have like, nooooo money for my hobby of electronics. I was going to get some on dx I think because It'll be cheap as hell and that's the most important factor for me.
I checked the link and that is a seriously ridiculous price for good alkaline batteries. I think I could make a lot of money off that here in nz. They cost 6-7 minimum here in stores, this crappy one was, I think, 5-6 dollars.
I need a charger chip badly, I've got a bunch of near new 2200 mah 1865 I (think is the number, they look a bit like an AA but a fair bit bigger, just scaled out) The batteries are Li Ion and 2200 MAh and I think it could be amazing. i could have a +- 12 volts supply potentially... I'm thinking a bag mount Pimeta, semi portable, not really pocketable, maybe in a huge jacket pocket... Hmmmm. I usually have a bag with me be it backpack or courier thing, man-bag, if you wanna call it that I get the feeling it could be very convenient and also sound awesome.
PS, speaking of diy... I got around to recabling a couple of headphones tonight.
my Sennheiser hd465's were starting to get crusty because I had used a cheapass jaycar plug with them. I switched it to similar jack as my other one, but 4 contacts. I grounded the mic channel. This stopped my android phone making my music stop with Google search, and drive me nuts by getting a bit of charge on the pause-play-skip-forward-and-back button contact. So far it seems effective. I spend a fair bit of time using just my phone or iPod (broken atm) when I'm out walking, don't have room for an amp in my pockets, and the wolfson chip on my nexus sounds pretty okay. I'm going to try out the in ears because I don't remember what they were like, I barely used them.
It's pic time! forgot to add them before so now I've gotta edit this in :D
These ones I've been super enjoying with my amp dac setup at the moment is these Samsung ones that came with my cell phone. I'd broken the cable around the plug, which was pretty well destroyed... Anyway, replaced it with a switchcraft plug. I guess that's technically not a recabling, hahaha. The part of this that's awesome about this, is these headphones are amazing. I've never heard in ears off an amp and good source until now. for 15 buck headphones I'm shocked really. the model is http://www.amazon.com/Samsung-Headphone-Handsfree-EHS44ASSBE-GH59-10443B/dp/B005FUNYV2/ref=cm_cr_pr_product_top, and people do seem to like them so maybe I just got a good model for free. I'm happy for 6 bucks of plug I'm enjoying having the music literally in my head.
Both of the headphones now have good connections and in the case of the 465's, much better quality. I was using the stock cable for 4-5 years now and it's gotten pretty worn out. They sound great because there's no more skipping and stuff. The cable I used was a silver-plated skinny mike cable I had laying around. I've finally got the perfect length of cable, and this one genuinely sounds better. maybe that's because something was wrong with my last one, but I'm glad any time it gets better!
Sweeeet! Everything I see on here keeps my motivation to finish the o2 more and more, and to make it awesome. I hope it is,. though I'm getting a second pcb (in red ) that I'm going to build up and turn into a hardout overkill desk model. But yeah... Coming soon. I'm waiting on a few vital components, but I shall post the rest of the build in the future
peace to all,
Hahaha, i've been using those same earbuds for about 2 and a half years now, i put a new connector on mine as well. I love their sound, it isn't crazy detailed or crazy bassy or anything, just right in the middle, perfectly average.
