Russian users of wireless headphones are increasingly faced with a situation where gadgets for no apparent reason begin to stall and wheeze, lose volume, and sometimes disconnect from the smartphone altogether. According to Izvestia, experts in the electronics market, as well as specialists in the use of radio frequencies, are also aware of malfunctions in the headphones.
Experts explained the reason is that wireless Bluetooth devices use the 2.4GHz frequency range, the capacity of which is limited. This range is also used by smart speakers and home Wi-Fi routers. The “noise” of the range can lead to interference. Wireless gadgets are starting to interfere with each other.
“One of the well–known problem places in Moscow is the corner of Nikolskaya Street and Red Square, where it is always crowded. Headphones often wheeze and stall at stadiums, in the subway and in other places where users congregate,” said Eldar Murtazin, a leading analyst at Mobile Research Group.
