“Welcome to the QC of what's supposed to be premium luxury products. Was a big part of what relieved me of the illusion of this hobby. Extreme high prices, low quality. HD650 for 10+ years strong”

“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.”

Best Praise

“Wife asked me what I wanted for Xmas and I was looking at the closed back sundara as a possible replacement for my HD569 for use on the Sofa. So sent it over but she stated she’d already gotten me my big present. So figured I would try and pick them up in January. But then this arrived. Nice surprise, looking forward to trying them out!”

“I ordered a brand new (supposedly) pair of Sundaras from HiFiMan's Amazon store, and upon opening the box I noticed white dusty stuff on the open back of the headphones, in the finer mesh material. I knew HiFiMan has a reputation for QC issues but I was not expecting *mold*. I contacted customer service about it and sent photos and microscope images. Here's hoping they have a good response. Definitely disappointed but I guess that's the risk you take.”
