Sony - WI-XB400
Hey there, thank you for the awesome ratings!
Very light weight, buds are very comfortable in ears... I'm not sure about listening music on these earphones, never tried them for music, as i am an audiophile so i prefer big headphones made for music listening...but is simply great for bluetooth pairing and talking on phone
or whatsapp.. charge once, and lasts whole day... absolutely go for it if your purpose is same as mine... talking on phone or WhatsApp for long times. Never doubt Sony.

Wireless Range
You must have most likely noticed that wireless signals do not travel an infinite distance. The farther a wireless signal goes, the weaker it gets. This loss is known as path loss, and it defines the range of connectivity. This range of connectivity is dependent on the wireless protocol in use like Bluetooth. Three classes offer standard ranges of connectivity with Class 1 devices transmitting at 100 mW with a range of 100 meters or 328 feet. Most Bluetooth headsets and headphones are Class 2 devices that transmit at 2.5 mW with a range of 10 meters or 33 feet. Lastly, Class 3 devices transmit at 1 mW with a range of fewer than 10 meters.
