I gave up on reviewing any earbuds because I can't make them fit.  Doesn't matter whichever way I stick them in my ears lol!!!  I'm guessing, but lack of bass is all due to "lack" of seal.  Really not a headphone fault, but a fault of our ear anatomy

You must have got a faulty piece...please return that immediately

Good review. Artificial is how id describe them too. Weird tunnel like sound. Poor qualty product all round the remote doesn't even work. Felt ripped off at £13
Buy Sennheser MX or akg k311 etc if you want decent cheap buds.
