I just received from Aliexpress the following Wireless earbuds
They sell for only 17.75 usd
Took only 5 minutes of fiddling to get them paired together then paired to my iphone
Bass isnt that great but otherwise they are quite usable.
Don't seem to have a volume control on earbuds
Having only just got them I obviously have no idea of longevity
So at this stage they are not a recommendation more information.
