Hi everyone, just wanted to share information here from the Sony WF-1000XM4 impressions thread.

Other than that problem which Sony are working on fixing with firmware update I'm very impressed with them, and releived I don't have to return them.
I didn't hear their sound signature before the last update but after the first day using EQ to brighten the sound I left EQ off last night, brain burn in set in fast and they don't sound too dark at all and have enough detail. Last week I was using my LG Tone Free FP9 (stock tips) and there was MORE bass than the Sony's (stock foams). I had to use the bass reduction EQ in wavelet because I was getting headaches.. This coming from someone who owns the Skullcandy Crusher Evo. Although maybe it was a combination of their bass and pressure from the ANC causing the headaches. Anyone here with the FP9 try different tips?
