Pros for the x3 nfc:Great battery lifeSuper fast charging with the included adapterGood performance including gaming. It was very easy to assemble and is very sturdy. I wanted truly functional and comfortable ear plugs that would help guard against hearing loss while I used my garden tools - these plugs have the 28 Noise Reduction Rating (NRR 28db) I needed. Im really tired, dont buy items not sold by Amazon. Since its a slip on style, the slipper itself slaps the floor (and stairs) noisily. I would have to buy replacement earbuds from Jabra which are $130. Im wearing them now as I speak. The Urbanites use a velour type material and Momentums use a real leather to cover the padding and both actually dont make my ears hot which is great. Its movement is super smooth. I like it so far!
