Yeah they’re pretty nice. The portability of TWS are also fantastic, I just slide them into my pocket if I don’t want to wear them anymore, transparency mode is better than the XM4’s. Albeit a small step down regarding ANC, since the WF-1000XM4’s have thicker eartips that do better for passive noise isolation. The APP2 also have slight better bass kick, at the expense of treble definition and midrange smoothness that the XM4’s have.

The design of the APP2 are also better IMO, easier to handle as there are more places to grip them. The WF-1000XM4’s are slippery everywhere else.

As for phone calls, APP2’s do better.

I don’t think I can go back to wired, no more snagging my wires on anything as I walk around, these were a huge pain (literally) when I was using my ER4XR’s on the go.

Sennheiser gifted a 660S2 in february, haven’t bought a headphone since. I sold everything else including my HD600.

My daily outdoor TWS are a pair of Airpods Pro 2.
