Ok so hope this helps:Delivery: no issues everything came boxed perfectly amd arrived 2 days before what was initially marked as the deliv. date.Sound: the sound very good buy out if the box the treble sounded muddy and distorted, once I played around with my phones equalizer it became much much better so I'd recommend that, the "voice prompts" sound as bad as you'd imagine from a semi-generic product though.Materials: the charging box has a very good/smooth feel to it, sturdy and very well built, only 4 little green lights indicate the current charge on the box (25% per light), the buds themselves feel so light in your hand you might feel they'd break easily but they are very resistant too, not implying that they'd survive a 2 story fall or a hammer hit but maybe a fall from pocket or your ear won't turn them into a million pieces like some do.Comfort: I feel conflicted in this sense but my experience is very particular being that one of my ears is smaller than the other to a noticeable degree when im comes to earbud sizes, and for one the extra rubbers material feel very cheap and in my case could not make them fit comfortably in one ear and at the same time because the material is low quality it ends up affecting the noice canceling, if you have others that are better quality and maybe fit on them, switch them out, no doubt about it.Battery life and connectivity: no issues there, haven't had to charge them yet after using one of them (single mode) for about 8 hrs, conection has been stable and have had no problems, ONE thing I noticed is that even though I had on put in the chatging box and the other on my ear, the one in the charge box was ON, I could hear the music coming from it and if I turn it off the other earpiece also turns off, so I don't know what's going on there because supposedly in single mode the one in box turns off automatically, and that's just not happening which is annoying thinking that it means that it's using up the battery when the point was to leave one off to be able to switch when the firstone runs out of battery, I'll update accordingly.Overall: 4/5I mean they cost 20 Cad. So for that price honestly you can't expect it to be out of this world, but if you need some cheap, light, long lasting, non-choppi, good sounding, in-ear buds, then you won't be disappointed, unless you're kidding yourself thinking these will replace your seinheisers or sony buds, lol.
