I am currently using the Bose QuietComfort 15 (QC15) , and it is no doubt the best active noise cancellation (ACN) headphones in the market. It is extremely useful especially when you are on a plane.
The Bose QuietComfort 35 (QC35)  is the updated model to Bose QC25 and Bose QC25 is the updated model to Bose QC15. What makes Bose QC35 stands out over Bose QC25 is the wireless capability.
Bose QC35 was launched in Singapore back in June 2016. It is retailing for S$599. Very often the retailers will give a $50 discount, making it S$549.
I have been eyeing on the Bose QC35 since it was launched. But I just could not bring myself to buying it due to the high price. However, thanks to my brother and his wife, Hui Min, they got the Bose QC35 as my 33rd birthday gift .
Bose QC35 uses a built-in rechargeable battery rather than a single AAA battery found in the Bose QC15. A single charge can last you about 20 hours of wireless playback or 40 hours of wired playback. It can be recharged using the included micro-USB cable.
- Powerful sound, wire-free
- World-class noise cancellation
- Quick-pair with NFC
- Enhance headphones with Bose Connect app
- Noise-rejecting microphone for calls
- Up to 20 hours per charge for wirless playback amd 40 hours for wired
- 1x QuietComfort 35 Wireless Headphones

I like how the airline adapter is being docked into the carrying case of the Bose QC35.
You can use the Bose Connect iOS app  or Android app  to further enchance the experience of your headphones like controlling it’s settings, updating it’s firmware and sharing music with another Bose wireless earphones/headphones.
