What is the recommended headphone hardware spec to pair with Apple Watch Series 2? Does Apple Watch Series 2 support all bluetooth headphones, or do I need to check for specific bluetooth requirements before buying?

Most of the sites suggest Beats Jaybird. Will the watch not work with common bluetooth headphones?
According to a support article from Apple the Apple Watch Series 2 has a Bluetooth 4.0 chip. So common bluetooth headphones should also work with the Watch.
