X966 Portable Wireless Bluetooth Speaker

A Good Portable Speaker: How to Choose One
To listen to music on a picnic, in the country or on a hike, you need portable speakers. Such devices have compact dimensions. Most models fit in a backpack or a  pocket, so they are easy to transport. Manufacturers equip the devices with various connectors (USB, mini-mini) for connecting to a tablet, smartphone, laptop, headphones. Some devices are equipped with Wi-Fi or Bluetooth modules for wireless connection.

Characteristics
To buy a suitable portable speaker, focus on its type and number of speakers. These parameters affect the sound quality and cost of the device. The lowest price is for 1.0 (mono) speakers. They reproduce sound only in 1 channel. Stereo models use 2 channels. Users can choose between 2.0 and 2.1 speaker systems. The latter are equipped with 2 speakers and a subwoofer for low frequency reproduction. You can also purchase a 4.0-type model. It provides more voluminous sound and, as a rule, is more expensive. Keep in mind: the device in a wooden case sounds better. A plastic device can rattle at high frequencies.

Power affects volume. When the maximum power threshold is reached, the Bluetooth speaker can withstand several seconds, so manufacturers do not recommend turning it on to maximum. In order for the device to last a long time, you should not turn the volume up above. Also pay attention to the power supply type. Devices that operate on batteries are lighter than rechargeable ones. They are convenient if there are no sockets nearby, which is confirmed by user reviews. The portable speaker can be powered by batteries or a charger. Some models operate from both energy sources.
