Design The headphones have a flashy design. They’re available in color combinations black/red. The headphones themselves are rather big. They almost look like professional in-ear monitors that artists wear. They also stick out your ear quite a bit, but they’re still comfortable to wear so that’s not a big problem. They’re also a bit on the heavy side making it uncomfortable to wear just one of them and leaving the other one hanging. Pairing The first thing to do when you buy Bluetooth headphones is to pair them with a device. Pairing is easy: hold the button on the earphones and wait till the LED blinks between blue and red. A female voice will alert you that you’re entering pairing mode. The headphones remember up to 6 bluetooth devices. That’s pretty practical: I was able to use them with my Mac at work and switch to my phone on the train, all without having to go through the pairing process again. Sound quality Well they’re actually pretty good! The bass is very loud with these headphones.
