I’ve had some wired CX300ii for about 15yrs they sound absolute amazing, so decided this year to buy some CX350BT’s thinking the specs were very similar to my 300s what could possibly go wrong, the battery life is good on the 350s the build quality appears to be ok too but the area it falls down massively on is sound quality, it’s woeful at best zero bass, tinny highs and miss, Purely by chance I find there is an app that can downloaded giving the opportunity to improve the sound, so I can now increase the bass marginally the kids and highs just distort when increased the depth and warmth is still nothing like the wired 300s oh and the max volume is literally half of the 300s too
