Jasprit Bumrah was seen wearing an earpiece at the Edgbaston stands during Day 3 of the 2nd Test between India and England on Friday (July 4).
The India pacer has been given a rest to manage his workload, despite having a 7-day break after the first Test. As the pace spearhead is not on duty, Bumrah could be seen enjoying the match from the stands.

During the action on Friday (July 4), Bumrah could be seen laughing while watching the match, with an earpiece around his ears. The visual has created a spark and interest among the fans, who remain curious to know about the device.
For the unversed, Jasprit Bumrah's earpiece is a miniature Radio, which provides live commentary for the match. In England, there is a tradition of radio commentary, which is typically done by the traditional media powerhouses - Sky Sports or the BBC.
Bumrah was wearing the earpiece which feeds the live commentary of the match. Not just the Indian pacer, the radio is available for the commentators at the media centre as well. Apart from that, even the fans can buy the radio and enjoy live match audio commentary inside the stadium. Even the players use the earpieces to remain engaged with the action on the pitch.
In most cases, the earpiece range is limited to the stadium. It means that spectators inside the stadium can only listen to the commentary, and they lose the connection beyond the stadium arena.
England was bowled out for 407 runs on Day 3 of the match, as the visitors led by 170 runs after 1st innings. Akash Deep picked up 4 wickets while Mohammed Siraj picked up 6 wickets for India, after Shubman Gill's 269 propelled India 587 runs.
