Summary-----------This headphone is an outstanding value. Not sure why would someone spend 300+ to get a Bose or Sony XM3. I Also have an XM3 and i can vouch for this headphone that it sounds the same.Build Quality---------------Its made of plastic (good quality) and the headphone has a metal band and I have a large head and it fits very well. The ear cups are also large enough to completely encapsulate my ears.The soundcore logo is prominent.No Headphone fatigue and it is not too tight and not too loose. Just Right!Charging-----------Finally, Anker came out with Type-C charger and i dont have to carry a micro-usb charger in addition to my phone charger which uses Type-C.I always make sure to charge the headphones to 100% before using, please do so.Pairing-------The headphones comes already in a pairing mode, so just turn it on and connect it to your phone or computer. The Q30 headset is capable of simultaneously connecting to two devices.Battery Life-------------Battery life is rated at 60H without noise cancelling and 40H with noise cancelling. I was not able to test the claim but it really last a long time!!Best part is 5-Min Charge = 4-Hour PlaytimePhone calls-------------I use this phone mainly for conference calls and zoom calls. Love the call quality and non one has ever complained of any issues. The 2 microphones work like a charm.Sound Quality-----------------The sound quality is outstanding, Highs, Mids, Low, all are balanced. i had an opportunity to compare it to soundcore Q20, XM3, Sony WH-XB700., Taotronics Soundsure 85.This thing beats everything except for XM3. I can hear the minute tunes which i was not previously able to hear in WH-XB700, Soundsurge 85 or Q20.Noise cancelling has 3 modes - Indoor, Outdoor and transport. Indoor reduces chatter, outdoor reduces traffic noise and transport is for reducing plane noises.I was able to test indoor mode and works great. True test is on a plane.Soundcore App------------------Everyone who buys this one should download the soundcore app and it lets you change from Normal to NC to Transparency (listen to conversation outside of your headphone).The soundcore app will also make sure your headphone is upto date with the software and will also let you use the equilizers.
