QuestionCan each piece be used independently from the other. For example can I use the left ear to listen to music and answer calls while the right is charging?
Asked 5 years ago by WhoseThatLady.
- Answer The right earbud is the main earbud, so you can use only the right bud by itself.

Questionare these noise cancelling earbud headphones as well?
Asked 5 years ago by TedC.
- Answer No, they are not. They are basically the same as the Sennheiser - MOMENTUM True Wireless 2, just without the active noise cancellation and transparent hearing mode. They’re also $100 dollars cheaper, so you have to decide whether those other two features are worth the price difference or not.

QuestionDo these work with just one earbud on?
Asked 4 years ago by DudeNeedsToKnow.
- Answer The right earbud WILL work independently, however the left earbud DOES NOT work independently of the right one. The left seems to require connection to the right one in order to work. As soon as the right earbud looses power or is returned to its case it will disconnect.

QuestionCan the other person hear what you're doing, ie washing dishes, clanging pots, shuffling paper, and so on?
Asked 4 years ago by Terri.
- Answer This has no noise cancellation, but it has good noise isolation so most of the surrounding noises are blocked out. You wont be able to hear other people's conversation if they are like 4 or 5 feet away.

QuestionHi, can these connect to my iPad? I haven't been able to connect them to my ipad.
Asked 4 years ago by Reta.
- Answer Try watching a short video on YouTube and make sure that your device is visible in “Settings” “Bluetooth”. After you pair the earbuds you should see the device here. Click on the device to connect. If earbuds are not showing in Bluetooth on IPad then pairing between the earbuds and the IPad has not taken place. Video was only about 5 minutes long. I am an older fellow and apprejlhensive like you but the manufacturers with their technology really make it seem easy. Good luck.

QuestionDoes it have International warranty?
Asked 4 years ago by Ak.
- Answer They come with a 2 year manufacturer warranty. I don't know if they take care of it in the US or over seas. Have only had them a couple weeks, I picked them up when they were on sale. So far they work fantastic and they seem to be very nice quality. They are worth purchasing.

QuestionSennheiser 400BT: Are the earbuds audio delayed at all when watching a movie/video?
Asked 4 years ago by Ifaf17.
- Answer I have had no issues with latency in my time using them (probably about 60+ hours at this point.) If you do begin to have issues with latency, make sure you are not too far from the device they are connected to. Turning off Bluetooth and turning back on, or even power cycling your device usually will fix any issues if they ever come up but again, I have had no issues.
