Beats wireless problem! Can't connect them to the Bluetooth

I just brought the wireless beats and I connected them to my iphone 5 but two hours later id got into the Bluetooth on my phone and i put "forget this device" accidentally and now i try to connect them again but the beats doesn't appear in the devices searcher.

Beats suck, and so does Bluetooth.neither one of them is reliable, and Beats are way too expensive for what you're getting. Instead, you should rather just get some $60 Logitech headphones, and don't get wireless headphones; it also raises the cost of the headphones but lowers the quality of the sound.
