Electrokart Tws4 Earbud With Noise-Cancelling & MIC. Before I tell you about the music experience, Also, don’t expect it to offer the same experience as in wired earphones of this price segment. The build quality of the earphones is impressive. It also comes with an official IPX4 rating, so it can survive the splash of water and sweat. It is also really light in weight and weighs just 13.6 grabs. So, it is comfortable for long usage. When you turn it on or off, it also plays voice notification to let you know if it is turned on or off. For pairing it with a new device, you need to understand one important thing. When you turn it on, you need to keep pressing the power button until the LED notification starts blinking fast. This puts the earphone in the pairing mode and voice notification says “Pairing mode”. When it comes to sound clarity, it impresses. I tested it with different kinds of tracks and it was good. It is loud, so the noise of the surrounding will not affect you when you are using it.
