I was wondering if anyone has a recommendation for a Bluetooth headset? I'd like to get one with Bluetooth 4.0 so it doesn't kill my iPhones battery like my current 2.1 earpiece. I would usually just use my EarPods but the will not work well for what I am doing. It also be nice if it had good sound quality so VoLTE sounds good on it but not necessary. Sub-$100 is a must though. Thanks in advanced!
