They do not fit very well nor stay in place. The range of ear bud sizes is weak and the "carrying case" is a small plastic ziplock. For $35 bucks they are "ok" for a gym bag but sadly not an frequent part of my exercise or lifestyle
Sound quality is...ok. Didn’t come with any instructions but was able to find a video online showing how to set it up. It does take a minute to set up. They literally showed up in a clear plastic bag thrown in and envelope. Would NOT get for a gift. Luckily these were just a pair to hold me over until I can afford better ones. Wouldn’t recommend them.
It was almost a month before I received them. The sound is great, but these refurbished Jaybird X2 came with two sets of large earbuds, that wouldn't stay in my ears. The wings helped a little, but I had to order a variety pack online. They're better now.
