My pair arrived today.
The cables are nasty, they crunch in the hand when straightening them. However, they don't seem to be microphonic. Measured about 1 ohm resistance. I checked continuity, normal layout, tip = left, sleeve = ground (thankfully). A 3.5 mm (1/8th in.) TRS male to female extension cable costs only a few pounds anyway so cheap and easy to replace that.
Seem to fit my head OK. Something odd about those wing things. Why the manual suggests adjusting anything I do not know, nothing slides. Maybe I didn't apply enough force? Maybe there is just no adjustment - self adjustment.
Pads are hard, and feel immediately cold on the head. They warm up after a few moments and then probably get too warm over a few hours. So far, so good, I haven't experienced discomfort.
The out of the box sound is OK, I wouldn't call them "treble canons" but there is definitely too much treble for sure. I hear what our host means by the lack of clarity at the same time. Bass is a pleasant surprise.
Sounds like I have a 1 dB channel imbalance favouring the right. So drop the right channel by that much and image shifts to centre/er, easy.
Using the EQ on the first page, with or without the low shelves.
Tempotec Sonata HD Pro has enough volume for me, I haven't maxed out the volume. I've gain at -4 dB from the EQ and music is target to -18 LUFS via ReplayGain.
A change for the better from the TakstarPro82 v1 - although I will keep working on an EQ for them.
edit: daft typo!
