Formally it is my first review here, but I'll tend to be short, since this headphones are not so bad from the box, but...
I have found 2 big problems, but correctable virtually at no cost.
1. May be I had a bad luck, since connected by original cable they sounded muddy, not much control over bass and recessed highs. So but only a direct cable solved a problem. Even a simple no name cable provided more details, more density (body) and punch for lows; slightly extended treble, but what was much more important for me - not so recessed. Since I use them only as headphones, not as headset with mic - fine for me. Less elements between amplifier and headphones, less items affecting sound quality.
(added later) Using a HiFi cable added precision to details and a little of body to lows. Not too much, but it was not a placebo effect. So they benefit from any HQ cable (3.5mm TRS stereo, male-to-male).
2. But even changing cable reduced a perception of muddiness to the a perception of foggy sound, when you hear details, but with smooth rounded edges (better to imagine a thin dark veil which allows to guess a details). It is easy to interpret using “sharp” tracks and comparing with a bunch of another headphones.
Since a construction allows to disassemble them easily I proceeded, trying to analyze which part of internal acoustics (the inner part of the headphone cup) gave such unpleasant effect, since external part was not a limitation factor. Overnight thought left me with only one solution. The cups are made from sturdy, but soft plastic with rough surface (micro scale) and sound wave reflections in all directions were causing such “veil” effect. So I filled tight the tiny insides of the cups with 4 pieces of multiuse reusable cloth like Handi Wipes and reassembled Revo's. This filling is not thick and dense as many dampening materials, so they “muted” multiple reflections, still allowing air to move quite free.
------------
This simple mod is reversible, so you can play a little bit using from 1 to 5 cuts of cloth for filling, but I like my result.

Bingo! No veil effect. ALL frequency range has detail now. The same quantity of bass, but now it had a bit more density, no change in punch, better control w/o getting boomy. Mids became clear and well articulated speaking of voices. Treble suffered most from being foggy, but now it is clean. Still neutral, so If you do not like harsh treble, modding and cable replacement won’t cause any problem.
BTW. They have a good amount of bass and have just enough of it, so I do not understand the slogan "Mass sound".
(added later) Since I am not using headphones for hours in hot weather and/or during tough physical activities, ergonomics and comfort are not the most crucial elements for me, but Revo’s are light, sturdy, well built and comfortable. Cable connectors at both cans also give more flexibility. And yes, they look pleasant for any age.
Recently I saw them with big discounts in many stores, so If you want to try elementary nondestructive modding and already have a HQ 3.5mm cable, you can get a good sounding headphones with very involving bass w/o any noticeable sound coloration. I tried all music genres, so you can have some fun also.
