Battery life could be better

Not 100 noise cancellation and the charge could last longer

Constant interruption when battery starts getting low and that is annoying but common among bluetooth devices

However i gave four stars because i cant stand the beeping noise it makes to let you know youve hit maximum volume

Weak volume level but sound good

Used them in 3 different devices and they work well in fact if you turned the bluetooth on all of them and had these buds connected previously they will automatically connect to all three at the same time

One thing ive noticed which is awesome is that while on ios device the standard audio is able to be turned up from the device with no problem but on android you can turn of the volume on the phone and then turn the volume up even louder using the buds

Which ive seen in one pair of wired earbuds bought at a gas station once
