A:AnswerIf watch has memory to store songs and Bluetooth then yes. But have to buy correct one. Bose has one for Apple devices and one for Android devices. Make sure you get correct one in store.
A:AnswerYes they can be used to any device that can connect to Bluetooth. They can be used while doing chores, exercising, and even as a hands free device while driving. I highly recommend you buy them!
A:AnswerI'm assuming you want to know whether the audio track will sync with the video when watching any video on your mobile device. This was a very important feature for me, and the Bose SoundSport headphones worked very well. While watching videos, I could not detect any lag in audio even during dialog scenes. I use an iPhone 6s Plus with iOS 10 and watched videos with Netflix, Google Play, and Xfinity TV apps.
A:AnswerThey are the best on the market and if right after Holiday season of course they will be out. But Bose did pull some initially because of moisture issues. All fixed and should be back in stock at all stores
