True dat, but my issue with BT isn’t the sound quality it’s the battery. I hate using battery powered headphones because they are just permanently dead in 5-10 years, where I expect my HD6XX to be on its 4th set of pads still going strong in 20. Throwing away Bluetooth devices also adds to e waste.

I'm not sure if the HD 6XX can really take too much EQ in the sub-bass because it could start to distort. The Edition XV not only has more sub-bass out of the box, but could probably handle a bigger boost in the sub-bass as well. In fact, poor sub-bass performance is why I sold my HD 660S2, as it just got destroyed by the Ananda Nano even though I put EQ on both of them. And the HD 660S2 is actually better in the sub-bass than the HD 6XX. Luckily, Sennheiser has been cooking recently with the HD 490 Pro which has some more sub-bass than the 660S2 and comfort better than the Ananda Nano.

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.
