Review on Dyplay Cancelling Wireless Bluetooth Headphones Accessories & Supplies by Peter Sullivan

Very good sound, but the battery is far from what it promises. The pair I received lasts 3 hours with no ANC or transparent mode enabled. I haven't fully drained the case's battery yet, but I fully charged the headphones twice and the LED indicator showed the case was at 25%. One more thing. ANC does not work as expected at all. These are the first headphones I've ever had with ANC, but apart from a faint buzz in the background, it's almost unnoticeable unless you try it on certain sounds. Using headphones as a headset with a microphone is useless. Before buying a Bluetooth headset, I didn't know that Bluetooth simply doesn't have enough bandwidth to support audio output and input simultaneously. I wish I knew about this and that ANC has very little effect before spending the extra cash on headphones with these features. For any potential buyers of these headphones, I would ditch them and maybe buy something cheaper or significantly more expensive. For the price, I at least expected the advertised battery life to be accurate, but unfortunately that's not the case.
