1. The inferior and inferior products have rough workmanship and low technological level. Things have advantages and disadvantages, and the things made by factories that implement strict standards are incomparable with those of processing plants and underground workshops. It is estimated that consumers can tell with the naked eye, such as whether the speaker net is made flat, whether the screws are firm, and whether the color is uniform.
2. Serious homogenization in appearance design, use male model, copy design. Most of the molds of fake and inferior products are male molds or plagiarized appearances. It can be said that they have no industrial design capabilities at all.
3. Substandard and inferior materials. Due to market competition, the quality of speaker materials on the market is currently very different, such as wire, good pure copper wire, the difference is basically copper clad aluminum, that is to say, the outside is plated with copper paint and the inside is aluminum. Such as a good plastic shell material, a good BBS material that has not undergone secondary use, a poor material for secondary recycling, and other materials.
4. Bluetooth transmission distance and transmission quality are limited. The Bluetooth chips used by brand manufacturers are all produced by well-known manufacturers, and the versions are higher, so the transmission distance and transmission quality are very good. The general transmission distance can reach 10 meters, and there is basically no loss in transmission quality, and the sound quality element can be fully interpreted.
5. Poor sound performance. The sound quality of a good Bluetooth speaker mainly depends on whether it can achieve the high, medium and low range of the bass that can be felt by the human ear. elasticity. And high, medium and low-level bass are clearly connected and connected in a loop.
6. The battery life is very short. The Bluetooth speakers have built-in batteries, which makes them truly wireless. The quality of the built-in battery directly determines the playback time and service life of the Bluetooth speaker. The lithium batteries used for brand Bluetooth speakers are generally original batteries with larger capacity and well-known brands. The quality is guaranteed. At a medium volume, the battery life of 1000 mAh can reach 10 hours. The refurbished lithium batteries or second-hand used batteries used in fake Bluetooth speakers have no quality guarantee at all, but there is a danger of explosion, so consumers must not choose them.
