I have had my Rose Auroras for a few days now. I am not as experienced at reviews but I will post what I found.
Sound:
Bass is present but a little too boomy for my tastes.
Mids and lower treble seem to be where the detail is. Overall warm signature with some treble roll off. Good for me since I am sensitive to treble and hate sibilance. Ironically these seem a little fatiguing due to the boomy bass as opposed to harsh treble. I am hopeful that with some EQ experimenting, these will work well. Right now the sound signature is not quite what I want. I like ample bass but not when it is boomy.
vs EPH100s.
Overall these are slower in bass (and more boomy) and lack some of the soundstage and clarity I had with my older Yamaha EPH100s. They probably deliver more bass in terms of volume but not as nice in quality.
Comfort:
I haven't had prior over ear style earbuds and was worried I wouldn't like these but so far, so good. The cable is relatively light and doesn't seem to bother me. The other advantage is that it seems to not get tangled up in a mess of knots like many others. I didn't notice much cable noise when walking the dog. I haven't gone cycling yet since I am back in Canada after living in Australia and subzero cycling is not appealing. Overall comfort is quite good.
Literally a few days after I ordered mine, they changed the product description at Pennon. You can now customize colours. I would have chosen red and blue or something to make it easy to differentiate left/right.
