Review on Sony WI C310 Wireless Ear Headphones by Cha Eunu ᠌

I looked after this option against the background of the fact that my wife uses the younger model wi-c200 and I did not see any shortcomings for my price tag in them. The older model seemed to be more perfect. But when using it, I began to notice that at a relatively short distance, communication with the device was lost. Trying to identify some pattern, I came across, as I think, an obvious trouble with the Bluetooth module in the headphones: I hold the unit with music control in my hand and only noise remains in the headphones, there is no disconnect, music continues to play on the device (accidental pause is excluded) . I checked my wife's wi-c200 - of course there was no such glitch. The store said that goods in this category are non-refundable and can only be sent for diagnostics to a service center. But, it seems to me, they would have been tested there in ideal conditions and a verdict would have been issued that they are serviceable. But the benefit was able to agree on a return without sending to the SC. Unfortunately, it is not known whether the store sent the device for diagnostics or returned it to the shelf. I see that there are similar reviews, so obviously the devices have problems with Bluetooth. Be careful in your choice.
