“No offense, mate.. but you have both the bass and the treble boosted.. No wonder those boring headphones suddenly sound better. They lack both bass and treble.. and can really use some EQ: [https://www.audiosciencereview.com/forum/index.php?attachments/sennheiser-hd650-measurements-frequency-response-png.101560/](https://www.audiosciencereview.com/forum/index.php?attachments/sennheiser-hd650-measurements-frequency-response-png.101560/) [https://www.audiosciencereview.com/forum/index.php?attachments/sennheiser-hd650-measurements-frequency-response-deviation-from-preference-png.101561/](https://www.audiosciencereview.com/forum/index.php?attachments/sennheiser-hd650-measurements-frequency-response-deviation-from-preference-png.101561/) I have the same amp, and it's an amazing piece of technology, but it doesn't have any magic sauce to improve headphones. What you need is headphones that you actually like.. or an equaliser that lets you play around with the FR of your HD650.”
