There are two things that I didn't see mentioned in the product description that are good to know:-When powered on, it maintains an active Bluetooth connection, even when using 2.4-Like a lot of Razer's revenge Bluetooth audio devices, this has a low-latency gaming mode. Discovered this in the user manual.I'll start off by saying that getting this device it's initial update was a huge hassle, but things have been smooth sailing since. Just try to follow the updater's directions as precisely as possible, it should work.The build quality is the weakest point as the exterior is primarily plastic. This is overshadowed by comfort, however, and the cushions feel soft and light.If you're looking for audio fidelity, I really hope you know you're in the wrong place. While I wouldn't say the fidelity is bad, I wouldn't say that's where these excel. Instead, features and function are what these do best.The directional audio is done very well, while the audio modes (ANC and Ambient) do what they say very well. I have 5 cats that tend to get into nonsense, and the ambient mode has allowed me to pay them proper attention while gaming. On the off chance I can zone in, the ANC completely cuts out fan noises and even most of whatever my partner is watching. Switching is simple and the headphones tell you what you just switched to. I almost wish I could completely skip ANC off since I never use it.The most surprising thing about these is how perfectly they fit my lifestyle. I don't always want to be at my desk to game, so I stream to my phone (bonus points for using Razer Kishi). The fact that I can just double tap the mode button and I'm now listening to my phone is awesome. No need to wait for pairing, and I've yet to have any connection issues. Mix in the gaming mode and suddenly these are the only headphones I use, period.Tl;dr: these headphones are all about the features, so make sure that's what is driving your choice before buying these. The features are extremely good, while the audio and build quality can feel middling.
