Sony XB41 Specifications

An iPhone with a Sony SRS XB41 speaker.

Here, we list Sony XB41 Extra Bass speaker specifications. Firstly, this info covers the unit’s length, width, weight, battery recharge time, output power, and music play time per charge. We also include the frequency response, driver size, Bluetooth support details et al.

Secondly, it’s clear from the published specifications, that the Sony XB41 released in January of 2018, sounds pretty good for as small as it is. E.g. It plays loud enough for small parties on patios, swimming pools, et al, with its approximately fifteen (15) watts RMS of audio power.

Plus, even at loudest volume, the lithium ion battery can last from four (4) to twenty-four (24) hours per recharge depending on the light setting, surrounding temperature, and program content. Indeed, the specifications certainly do not mislead as to the great features Sony put into this IPX7 water resistant Bluetooth speaker.
