The headphones are very good at switching between multiple connections. I had my pair of QC35s connected to both my laptop and my phone, and the headphones had no trouble switching between the two as I played music alternately from both devices. Battery life on the QC35s is very good. Bose promises that the headphones will last 20 hours when operating wirelessly, which rises to 40 hours when used as a pair of wired headphones. I didn't time exactly how long the battery took to run down, but the headphones lasted me several days of on and off use before needing to be recharged. The headphones that came before these, the Bose QuietComfort 25 , enjoyed a huge amount of success after arriving in 2014. In the years since, the number of wireless models on the market has exploded, meaning Bose had to make the jump to wireless sooner or later. Bose took the already-excellent QC35 and updated with Google Assistant. The headphone is identical in every way save for the new Google Assistant button. This means you still get the class-leading noise cancellation Bose is known for, good sound quality, and incredible comfort.

Bose’s forte is active noise cancellation and it shows with the QC35 II NC. Switching on noise cancellation is like walking into a quiet room after being on a busy city street. The headphone does an excellent job of drowning out everything from the rumble of a train, cars driving by and even voices. No matter how much confidence you place in a brand, there are bound to be some hiccups with its products or flat-out duds. One of Bluetooth audio’s greatest shortcomings is reliability, relative to its wired alternative, so here are a number of ways to fix any wireless connection issues that arise. The headphones won’t re-connect to your phone So first things first, nothing with the sound quality has changed significantly when compared to the first version. The Bose QuietComfort 35 II follows our headphone preference curve for headphones very well. Of course, you can always equalize your headphones to change things around to your tastes, but this kind of performance allows you to do that out of the box — like I said, really cool. Lows, mids, and highs In terms of sound, the Bose QC35 II NC is good, but not class leading. While tonal balance is relatively neutral with a slight mid-bass bump, the sound is somewhat soft when compared to competitors like the Sony WH-1000X M2 (previously the Sony MDR-1000X). This means dynamic range is a bit limited and makes for a somewhat dull presentation. Resolution is good but not great and sound stage is about average.It's also strange using the headphones when they're cancelling out the noise around you (including your own voice), but the microphone works very well despite not being located on a cable closer to your mouth like most wired headphones. If we have one complaint, it’s that the noise-cancellation could be a little more intelligent, for example in the same way the Sony WH-1000XM3 headphones disable noise-cancellation when you hold your hand over one of the housings. While it's now a few years old, the QuietComfort 35 II offer both wireless operation and active noise cancellation as well as built-in support for Google Assistant.

Have you tried turning them off and on again? I know, this seems basic, but you’d be surprised how many technological bugs can be fixed with a simple reboot. If this doesn’t work, continue on to the next steps.I used the headphones for a half hour video call in a noisy office and was perfectly audible throughout thanks to the efforts of the noise-cancelling technology. We liked Being an owner of other BOSE products, I knew I would love them. I just did not realize how much I would love them. Amazing comfort and sound quality. Very happy with them. Of course the primary use is Wireless, but I also have a device that requires Wired, so that worked out great with the accessory cable.
