I noticed them both when I was putting the shoes on in the morning before I tried to tighten them. The depth and separation however is excellent and the ability to pick up the directional cues in the audio is seamless as a result. With the MEGABLAST the sound is very CONSISTENT. They offer great mileage, comfort, light, breathable, sturdy but not too stiff. The color is great though! The only reason I say these are the 2nd best pair of slippers I have ever owned, is because my favourite pair, were hand me downs, and WAY more expensive. It is sooooo functional. All in all this is pretty fun, and I didnt have to redo my Steam VR settings so if I want to play other games standing I can just move the chair out of the way. The elastic has enough give that they stay on well, but at the same time do not cause discomfort atop my VERY high arches. The ear pieces are big, and they can be very loud if youre into that.
