How to choice a Bluetooth Speaker

1.compatibility

Although the compatibility of Bluetooth speakers is basically 100% support for existing Bluetooth devices, but you still need to check whether your playback device supports Bluetooth before buying it.

2.transmission distance

The transmission distance of the Bluetooth speaker is also a problem of great concern to everyone. The transmission distance of the Bluetooth speaker has nothing to do with the Bluetooth version, but mainly depends on the advanced degree of the technology. The PowerClass2 standard transmission distance of 10 meters, while the upgraded PowerClass1 increases the transmission distance to 100 meters and provides Hi-Fi stereo effects. Generally speaking, the distance between the mobile phone and the Bluetooth speaker is not too far, and the safe transmission distance is about 10 meters. Market Bluetooth speakers have reached the standard of 10 meters.

3.edition

When consumers purchase Bluetooth speakers, they often see Bluetooth 1.1,1.2,1.2,2.0,2.1,3.0,4.0 and other numbers, these numbers represent different versions, but also represent the Bluetooth speaker anti-interference ability. In 2012,2.0 was the most common, 3.0 was the new mainstream, and 4.0 was just launched. Bluetooth version is different, about the quality of receiving signal. The new version puts more emphasis on overcoming distractions. The new version can be downward compatible, and consumers should measure the price and demand when buying.

4.internal battery

Bluetooth digital speakers are built-in batteries, to achieve the real wireless. The good and bad of the built-in battery directly determines the playback time and service life of the Bluetooth digital speaker. Please ask carefully about the actual play time and repeated charging decay times before purchase. It is suggested that consumers should choose polymer lithium battery when choosing Bluetooth speaker, with no explosion risk.
