CedricPrivat6 years ago+220Is this headphone the successor of the XQISIT oE400 ANC? Or what is the difference between the two?Show in original language (German)kitsos001016 years ago • purchased this product-112purchased this productApparently a better model but not the successor. I bought the OE500 and I find good value for money. I would not recommend the OE400 because the tonality is not so good.Show in original language (German)Comment
