[Q] is a bluetooth headset version3 compatible with android jellybean 4.1.1?

hi:)

i have an m155 plantronics bluetooth headset which has a specification of bluetooth version 3.

when i use it with my android jellybean 4.1.1 mobile phone ALCATEL 5035E (unrooted) to play music, the music stutters,
drops off, then resumes, then finally drops off completely without resuming, although bluetooth
icon remains blue. i touched the bluetooth icon to disconnect it. the icon
blinks and does not stop.

i brought my mobile phone for service and they replaced my phone with a brand new one. but the same problem occurred.

the technicians said it could be a problem with the bluetooth compatibility with the android jellybean. they said to update my bluetooth device so that it becomes compatible with the android 4.1.1. i was skeptical because i had this vague thought that there is no such thing as updating the software on a bluetooth headset.

i checked on my android device, and the bluetooth version on the mobile phone is 4.1.1-1350

sorry if i sound stupid to ask you guys. but i need to give the technicians an answer so that we can move forward in finding the problem. Your answer will help us go in the right direction.

does the bluetooth headset need to be the same version with the android phone in order for it to function properly?

is there an android update that fixes my issue? if so, how do i get it?

thanks much:)
