If you are looking for Bluetooth headphones to pair with a smartphone or tablet, you might take a look at the Oontz BudZ 2 headphones. I just bought a pair from Amazon for $18. Paired them with my iPhone X, and I'm really impressed with these headphones (or earbuds). Good listening quality and with the rubber tips, they stay in my ears much better than the Apple EarPods I recently bought for $150.
Now, I'm not saying they're as good as the EarPods, but for the money, quiet decent. And I don't know about the long-term quality, either. But for the money, I thought I'd take a gamble. One nit-pick on Apple's EarPods -- the small instruction sheet sent with them is on paper that has very small print that is light-colored and hard to read. The instruction booklet that came with the OontZ earbuds has black ink in a larger size that is so much easier to read. Comparing the two instruction booklets is like comparing night and day. Apple should take a lesson from this -- their instruction booklet is yucky and cheap-looking!
