Thx for the suggestion pal. I've got the Bose Soundsport for running and PXC 550 for travelling. The Sony wireless I tried (both TW and Over Ears) didn't impress me as much as what I currently own. If and when I do upgrade, I've got my eyes set on the B&O E8/ Sennheiser for Truly Wireless and the B&O H9i for over ears. (The PX7 & P9s from B&W are the only ones that sounded better than the H9i, but I couldn't stand the clamping force for over 30 mins) But I, digress. The reason for a beater pairs of wired are, I don't think I'm using the ZX300 enough. It's barely seeing 30-45 mins of usage a day. Often via bluetooth & the battery life takes a beating. Additionally, with wired, I'll have one less gadget to charge.
