Meizu, along with three smartphones, also launched the EP52 Lite water-resistant Bluetooth Earphones and Halo headset, which is a Bluetooth in-ear headset. The EP52 Lite earphones targeted at runners and outdoor users under the EP series. Since EP52 works over Bluetooth, it is completely wireless and at a mere 16 grams, these headphones are fairly lightweight as well. Considering these earphones are waterproof (IPX5), the earbuds feature a nano-coating that makes it sweat and waterproof.
