What is the difference between Bose qc35 Series 1 and 2?
1) Bose QC35 turning ON by itself / Bose QC35 keeps restarting
To know the answer of this famous question I went through 100 pages on Bose community where the thread has started from 2017 and still continued to page 100 in year 2020 !! indicating that this problem is persistent over years
Same about reddit threads …
https://www.reddit.com/r/bose/comments/8mg54p/bose_qc35_turns_itself_on_automatically/
So finally I concluded that if you are facing the problem of Bose QC35 turning ON by itself / Bose QC35 keeps restarting is because of hardware issue and it has got nothing to do with firmware update or its not a software issue either.
It is purely since the hardware is faulty or the headphone switch is faulty.
so this leaves with below two options depending upon the product is in warranty or not.
Option 1 – Warranty valid
If your headphones are under warranty, then goto local Bose store and ask for replacement.
If warranty is valid then do not attempt to do repairs on your own, opening the headset will make the warranty void.
Option 2 – Out of Warranty
If your product is out of warranty. Then you can try insisting that their own official community shows that problem is persistent over years and ask for free exchange. Escalate over emails and public forums multiple times. There are examples of people getting “One time exchange” so no harm in trying hard to save precious money.
If at all you are not successful getting Free replacement, only way left is to get it repaired locally or send to Bose for repairs.
Now what is left to you is try checking if the Power Switch is faulty and repair it on your own.
Its not that difficult but not that easy too, any wrong step can ruin the headphones, so check the video below and try steps carefully.
How to check your headphone’s switch is faulty?
Try the following …
- Connect your headphones QC35 to your Bluetooth device, say an iPhone
- Turn the QC35 ON/OFF switch to the OFF position.
- If the green light comes back on by itself, it might indicate a bad ON/OFF switch on the QC35.

7) Bose qc35 battery replacement
The bose qc35 battery is expected to retain 80% of its original capacity after 500 full charging cycles (ref article). So it should last for approximate lifespan of 3 years.
As a normal user this life shall be sufficient, but in case you are intense user and the battery gives up early, then you need to remember that the battery inside the QC35 is not user replaceable.
However if you are fond of electronics and used to handle soldering gun with ease, then replacing battery should not be an issue – simply refer to below video which demonstrates in very detailed way on how to replace battery of qc35 headphones
8) Can you use Bose qc35 without battery?
Yes, you can use Bosc qc35 headphones without battery, using an AUX cable connection.
However it is important to note that noise cancelling, controls on the headset, and the microphone will not work as they require a Bluetooth connection.
9) What is the difference between Bose qc35 Series 1 and 2?
Everything in Series II is same as Series I headphones including the design, fit, sound quality, battery life, noise-cancellation.
So only difference in Series II is the inclusion of Google Assistant and Alexa.
Hence the new QC35 II have a long, flat button on the left earcup that lets your headphones communicate with the Google Assistant.
