Technics EAH-A800-S Wireless Noise Cancelling Headphones - 50H Battery Life, Hi-Fi Bluetooth, Multi-Point Connectivity, Crystal Clear Calls | Premium Comfort for Travel, Work & Music Lovers (Silver)

So I have been waiting for these for a few months now and I can say these are excellent headphones. I also have owned these which I will compare them to:Bowers & Wilkens PXSony 1000 MX3Master Dynamic MG20So first off these feel well made but not overly heavy like the B&W PX, and not as light or cheap feeling as the Sony's. The app works well has a lot of features and does not force you to turn on location. You don't need the app but it is nice and works well. There was a firmware update that applied pretty quickly and they actually described the update and what it added/fixed which is nice as most companies don't really tell you. The voiced turning on/off prompts are nice, very clear and what's cool is you can change the prompt language as well. I set mine to japanese and I like the voice, lol!The headphones are more comfortable than the Sony's and the PX's over time, my glasses didn't dig in to my face and the clamping force is pretty much spot on. Inside the ear cups there is clear large letters for Left and Right which lets you put them on much faster. With the Sony's I had to search for the small L/R text and was always annoying. The PX isn't to clear either on the left and right positioning. The PX I had I gave away as one of the volume buttons stopped responding and I had to adjust it from the device everytime. Bowers & Wilkens support is terrible and weeks of emails they still refused to help me solve the problem. I considered the PX7 but the carbon infused plastic they use on the frame is a poor choice and will snap on impact as it is very brittle and not made for flexibility. I am a Mechanical Design Engineer and can tell you that was a terrible material choice. You can also look at the reviews and see how many people have had them snap. They do sound good though just like the PX but the new ones build quality is poor.The Technics has multi device connectivity which is great as I connect to my phone and PC at the same time and its a smooth swap when calls come in. There are 8 mics (4 for NR) and the call test I did were well recieved my my friends even in breezy area was very clear on the other end.The battery is the biggest draw here and I actually got more then 50 hrs on the first session as I did not have noise reduction on max. You can also choose your level of ambient noise in, there are lots of settings in the app.There are physical buttons for volume/power/pairing which is nice. I am not a fan of touch interface but you can also set up the touch style functions you want through the app as one of the earcup outer panels is a touch interface.The sound is very good for my use, they require high end input to appreciate them and I do not have that so best search other reviews for high end stuff. I watch movies, audiobooks, and PC games and its great for my needs probably more than I need.The Master Dynamic MG20's I returned through RMA, for $500 I expected great stuff but it has this stupid auto off feature thet turns off the headphone after 10-15 minutes of use if it doesnt detect movement. I mean If I am sitting and watching TV or on the PC or even plane I'm not really moving around alot and it was so frustrating as they were very good headphones otherwise especially the build quality. These also have a stupid app that requires your location to be on.Anyways for the price these are great, they are not cheap, but they are not price gouging either like some brands. The tech is cutting edge, battery life is the best on the market and they look good in an office setting, public or anywhere. I hope this review helps people with their decisions.
