I may be getting some wireless headphones soon so I thought I'd sync some music to my Apple Watch. Since I only use for a handful of apps and notifications it has plenty of space. Apple limits this to 2GB. Here's my question, does the music have to be what's on my iPhone in terms of quality? It appears that this may be the case from Apple's website. I sync lossless to my iPhone. On my watch there is no need for anything above 256 iTunes quality and I could fit far more music on it. However, does this mean that I'd have to have compressed music on my iPhone too? Thanks.
