How To Choose The Right Bluetooth Speaker?


Although the compatibility of the Bluetooth speaker basically supports 100% of the existing Bluetooth devices, it is still necessary to check whether the playback device of the Bluetooth speaker supports Bluetooth.

Transmission distance

Bluetooth speaker transmission distance is also a problem that we are more concerned about. The transmission distance of the Bluetooth speaker is independent of the Bluetooth version and mainly depends on the advanced level of technology. The PowerClass2 has a standard transmission distance of 10 meters. The upgraded PowerClass1 increases the transmission distance to 100 meters and provides Hi-Fi stereo effects. In general, the distance between the mobile phone and the Bluetooth speaker is not too far, and the relatively safe transmission distance is within 10 meters. Bluetooth speakers in the market reach the standard of 10 meters.


When consumers purchase Bluetooth speakers, they often see Bluetooth 1.1, 1.2, 2.0, 2.1, 3.0, 4.0 and other figures, which represent the different versions, but also represents the Bluetooth speaker anti-jamming capability. In 2012, 2.0 was the most common, 3.0 was the new mainstream, and 4.0 was just launched. Different versions of Bluetooth relate to the quality of the received signal. The new version emphasizes more to overcome noise interference. The new version can be backwards compatible, consumers should measure the price and demand.

Built-in battery

The Bluetooth digital speakers have built-in batteries and are truly wireless. The quality of the built-in battery directly determines the playback time and service life of the Bluetooth digital speakers. Please inquire about the actual playback time and repeated charge decay times before purchasing. It is suggested that consumers choose lithium polymer battery as much as possible when choosing Bluetooth Bluetooth speaker, no risk of explosion.

Battery type:

1)Polymer battery

Advantages: safe and efficient, soft package without explosion hazards.

Disadvantages: Variety of types, pure cobalt (good) and pure manganese (poor) polymer battery difference several times.

2) 18650 battery

Advantages: excellent performance, can reach the highest level of charge and discharge (used for laptop batteries), explosion protection

Disadvantages: Disassemble battery and old battery more. The same 18650 battery good and bad bad 5-10 times

3) Aluminum shell battery

Advantages: The price is very cheap

Disadvantages: poor performance. Without any explosion protection measures, the consequences of an explosion can be disastrous.

Battery protection board:

1) The battery protection board of the brand-name battery is relatively poor in charge and discharge protection, and unstable and easy to damage the battery core and electronic equipment.

2) Unstable current output not only affects the sound quality, but also causes a large current sound.

After a good quality battery is charged and discharged 500 times, it can reach 80% of the initial capacity. Poor quality batteries do not even reach 50% of the initial capacity after 100 charge and discharge times.
