How is series 2 different from series 1

Thank you for your question. QuietComfort 35 headphones II offer the same unmatched combination of acclaimed noise reduction technology, wireless freedom, audio performance, dual-microphone system and 20-hour battery life as QuietComfort 35 headphones. However, QuietComfort 35 wireless headphones II also have a new Action button on the left earcup. In countries where the Google Assistant is available, that button gives you instant access to the Google Assistant, your own personal Google. In countries where the Google Assistant is not available, it lets you quickly toggle through three different ANR settings for optimal performance wherever you go. We hope this helps!

When using them for a call, do you need a mic on a cord or do the headphones have a built in microphone to pick up your voice?

Hi, thank you for the interest in the QC 35 Series II headset! You do not need an additional inline cable with a microphone. To confirm, the headset has the mic built into the earcup and is active when on phone calls. Hope this helps! Thank you

i work on trains with loud noise it excess of 90 db. with these headphones work in that environment???

Human hearing is very fragile. Noise levels above 85 dba for extended periods can be harmful to your hearing. Human hearing on average can't distinguish changes in sound pressure level less than ~3db. A 5db change, up or down, is clearly noticeable and a 10db change, up or down, will be perceived as a doubling or halving of the volume respectfully. If the unit does not provide specifications on noise reduction across a band I would not use as hearing protection in a noisy environment. There are bluetooth enabled over the ear muffs, or in the ear buds that provide greater than 20 db of noise reduction.

how long does the battery last if you turn off the noise cancellation (wireless)?

Hello, thank you for your question. When the headphones are turned on and being used wirelessly, you will get up to 20-hours of battery life. If you turn off the headphones while they are being used wirelessly, this turns off both the Bluetooth and noise-cancellation. With the headphones turned on and the backup audio cable connected, Bluetooth will be disabled however you will get up to 40-hours of noise-cancellation. We hope this helps!
