Frankly dude, if you're deaf in one ear you'd be better off posting a WTB classified for one side - it'd save you a helluva lotta money. Normally single-sides go for a fraction of the original price..
Also, for IEMS like the se215/um1/W1, wearing em non over-ear is kinda... hard. Not impossible, but I'd expect it to be very unnatural/possibly uncomfortable.
+1 for the JH5. IMO for the price you're paying the JH5 is a bloody steal. Spectacular comfort, isolation and sound - they do have a bass hump like most JH IEMs though, but it doesn't muddy the mids/highs or anything. And if you're quick enough JH Audio is having a 15% sale now so that'd be LESS THAN HALF your budget.
Aww dude, a comparison might just convince me to grab myself a AS-1 as well. They only thing that's been holding me back is the ASG-2 upgrade soon to come.. Heh yeah... I've been so damn tempted to grab myself a Heir 4.A/8.A/3.Ai considering the glowing reviews that have been pouring in... Any thoughts/comparisons on those, btw? And I notice you've got a Pico Slim for sale - have you tried those with the ASG-1.2? It really might make you reconsider selling ;D
