A:AnswerThe manufactory warranty Samsung provides is useless for this product. It does not cover lost or damages parts and the galaxy buds are very easy to damage or lose. If you do decide to purchase make sure you can purchase insurance that covers damaged or lost items through BestBuy because Samsung will not replace it. If you do lose one of the ear buds, they still will work but you will no longer be able to receive software updates.
A:AnswerHello sony, great question! These earbuds can only be used with a smartphone and tablet running Android 5.0 or higher & RAM 1.5GB above and iOS. Automatic sync and Ambient Aware Mode only available for Android; iOS users can use Voice Command/Siri. ^Elizabeth
A:AnswerThe Galaxy Buds do not offer active noise-cancelling. They do, however, attenuate external sounds quite well, especially when used with good, third-party eartips like those from Comply or JLab. I'd find these quite acceptable for a short-to-medium-distance flight.
A:AnswerThe extra parts are for your ear. If the buds dont fit you can switch out and putting on the size that fits your ear better. What ever is more comfortable in your is what you should use.
