How to select the right  Bluetooth speaker wholesale price

compatibility

Although the compatibility of the Bluetooth speaker is 100% supported by the existing Bluetooth devices, you should check whether your broadcast device supports Bluetooth before buying.


Transmission interval

The transmission interval of Bluetooth speaker is also a concern. The transmission interval of the Bluetooth speaker is not related to the Bluetooth version, but mainly depends on the advanced level of skills. The standard transmission interval of PowerClass2 is 10m; The upgraded PowerClass1 improves the transmission interval to 100 meters and provides Hi Fi stereo function. 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. The Bluetooth speakers on the city roads all reach the 10m standard.


edition

When purchasing Bluetooth speaker , consumers often see Bluetooth 1.1, 1.2, 2.0, 2.1, 3.0, 4.0 and other numbers. These numbers represent different versions and also represent the anti-interference ability of Bluetooth speakers. In 2012, 2.0 was the most popular, 3.0 was the new mainstream, and 4.0 was just launched. Different versions of Bluetooth are related to the quality of received signals. The new version focuses more on overcoming noise interference. The new version can be downward compatible, and consumers should measure the price and demand when purchasing


Built in battery

All Bluetooth digital speakers have built-in batteries, which makes them truly wireless. The good or bad of the built-in battery directly determines the broadcasting time and service life of the Bluetooth digital speakers. Please carefully inquire about the actual broadcast time and the number of times of repeated charge attenuation before purchasing. It is suggested that consumers should choose polymer lithium batteries as far as possible when choosing Bluetooth speakers, which is free from explosion risk.Bluetooth speaker wholesale price
