got these on tuesday the 14th, they dont have 15 metre range or even 1 metre, i put the left bud in my hand and moved it a metre away and it cut out the audio and disconnected from my phone, they randomly disconnected from my phone while my phone was in my pocket, when i got it there was a piece of plastic wedged in one of the pins so one ear wouldn't charge (this was mostly fixable, and now the right ear won't charge at all (tried the left on both chargers and worked fine), the audio has constant hissing and quieter background audio sounds as if it was played from an N64. don't buy these. trust me.
