Order placed!
 
So I ordered the Xiaomi Piston 2 and the Havi B3 Pro1 with that eBay birthday coupon! Thanks you to everyone who helped fund this purchase. :3 I wanted to order the TTPOD T1E as well, but unfortunately the cool transparent / crystal colour is out of stock at the moment. There's just a bit left over in this month's budget to get a pair of Audio Technica IM50 or IM70's (trying to decide which one to order?) Looks like it'll be an earphone month!
