Electrokart SM Gold BT21 Wireless Neckband With MIC

Electrokart SM Gold BT21 Wireless Neckband With MIC. Before I tell you about the music experience, you shouldn’t forget that it costs just Rs. 699.

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. Electrokart SM Gold BT21 Wireless Neckband With MIC With Mic claims dynamic bass feature that didn’t impress. The bass is average, so it will disappoint you if you love bass heavy music. The same goes for the treble. It means this earphone is not for you if you are looking for good music experience, then you will also have to increase your budget because not many options are there in this price segment. I find it good considering the price
It supports Bluetooth 4.1 connectivity with Bluetooth profiles like HFP, A2DP, HSP, and AVRCP. As soon as you turn it on, it instantly connects to the phone it was already paired if Phone’s Bluetooth is on. It also works fine under the Bluetooth’s operating range.

As it has a microphone, you can use it for hands-free calls. Just press the center button to accept the call and start talking. The microphone performs well and it captures your proper voice
It packs 180 mAh battery and the battery lasts for around 15 hours in regular usage. My usages were mixed with tracks on high and medium sound levels with not many calls. If you will use it on high volume all the time, battery back up will be lower. The battery takes around one and a half-hour in fully charging.
This earphone is good for regular use when you need a Bluetooth earphone for hands-free calls and occasionally listening to music. I don’t recommend it to music freaks, but it is still good enough considering its price
