Not as loud as you would want I don't think.
I would recommend you a pair of Votomy V22 instead, they are also much cheaper, they are crazy loud and still have very good sound.
I have 2 pairs of the silver 2nd generation. Reason being I thought someone had stolen my 1st pair. We had some theft at work, when I went to use my buds they were missing from the case. So I bought a second pair.
Ahead 3 months later, turns out my cat knocked them off my night stand and they fell out.
The 2nd pair I bought ended up going through the washing machine. THEY STILL WORK! I've had no problem with either pair. Best wireless ears buds I own!
Lol, tapped my case into my coffee about two months back.
Oh yeah... and my cup was half full, so was the case.
There's an LI in there... damage can happen real fast with a powered up circuit if it gets wet.
Maybe the new plus buds have a case that more water or in this case coffee resistant but these don't; flooded in it did.
Popped the case apart immediately, cleaned with water then anhydrous isopropyl. Blew off as much as possible with a bulb blower and let stand to dry completely.
Prayed to the patron Android saint of idiots...
At first charging on the case was slow, however 2 months latter it's still ticking.
This incident may eventually kill it though...
