MOVSSOU W058 E7 Active Noise Cancelling Headphones (Open Box)

These are pretty good in some ways but bad in others and one features is strangely good and bad.The noise cancelling is really good, when I remember to turn it on. I've had 2 other headphones that ANC was a mechanic switch, the upside is that you can enable ANC even with them turned off. The rest have always required the power to be on for ANC to work but they also had ANC on by default.The over all sound quality is pretty good for my use case. I don't use them to listen to music on my phone or some other device. I mostly use it for watching TV/movies and playing games on my PC.The comfort is pretty good. There is one thing I don't like is what happens with my ears. After wearing them for a while there can be bit of discomfort on the back of my ears. Readjusting them can help for a while but it tends to come back. So that's a bit of a star off.The volume control isn't great. Every time I press the up or down controls it might actually adjust the volume or it might not. But speaking of volume every time you turn these on they volume is always reset back to 80%, which if you forget about that can be a real painful reminder. Yet another bit of a star off.Bluetooth syncing this is a strange one. I use a bluetooth transmitter for my TV and PC. So normally I can leave the transmitter on, turn on my previous headphones and it syncs with no issue. But with these, not so much. I have to turn off the transmitter, turn the headphones then turn on the transmitter. If I leave the transmitter on and turn these on, the light on the headphones goes steady as if it's connected to something but the transmitter acts like nothing is connected. I've tried with a different transmitter and I can leave it on, turn on the headphones and it'll sync just fine but that transmitter has other issues I'd rather not go into. So yep, a bit more of a star knocked off which completes the first star off.Now comes the reason for a whole star coming off all on it's own and the most confusing thing I've seen yet; the battery life. These are advertised as 30 hours. I always do two tests; one with ANC on and the other with ANC off. In the past the headphones would say they get 30-40 hours with ANC on and they don't come close, not unless the volume is really low. I won't name brands but one was a $130 well known says 35 hours with ANC, more like 25 hours. Another lesser known brand but listed as 40 hours, best case was 38 hours with the volume half way up. On the other had, these same headphones with ANC off will get 50 and 65 hours, which you would expect. So how do these do? Ready for the confusion? With ANC on the battery got 36 hours. Pretty good right? So why with ANC off does it only get 38 hours? You would think that with ANC off it should be like the other and getting twice the battery life but nope, it don't. I'm just really really confused.Over all for the price these are really good. I also have to admit I'm confused why the ones marked "Black" are actually red and so much cheaper (at the time of purchase).
