After about a decade of faithful service, my beloved workout companion, the Sennheiser PX100 (the original version, not the current, 2nd version) broke. One headphone broke off from the headband after years of abuse in my gym bag.
I thus now turn to the collective wisdom of WS for a replacement.
The PX-100 II is certainly an option. But I've seen many interesting new entrants like the B&W.
I will use these headphones plugged straight into an iPad / iPhone. As a WS member, I know I sould be striving for a neutral, honest, transparent sound. As a long-time WS member, we also know that this hobby is about finding the right set of compromises. So I'd go out on a limb and say that I will use this in the gym most of the time so I'd like a lively, energetic sound. Grado's seem to suit but for some reason, i've never gotten around to picking one up.
