In the Chinese market, Tianlong did not pay attention to the Bluetooth speaker product line, and its popularity was seriously insufficient. Tianlong's products are benchmarked against the BOSE Soundlink Mini series, but BOSE's brand power completely crushes Tianlong. In fact, the product power of Tianlong Bluetooth speakers from the previous generation has surpassed BOSE's Soundlink Mini, especially after the replacement of the DSB series The price is similar to that of Soundlink Mini II, and the product can even beat Mini II in some aspects, but the sales have been relatively flat.
 
Compared with BOSE,Tianlong's weakness is mainly in industrial design,Its portable Bluetooth speaker is not popular enough,In addition to not being well-known enough,It is more or less related to this,Its shape is pillow,The design is slightly monotonous,The plastic material on the side is slightly cheap。 DSB series is Tianlong's only portable Bluetooth speaker product line,The latest DSB50BT、DSB150BT、DSB250BT are made of metal silicone,There is already a relatively unified design language,Low-key and calm,The smallest pocket model50BTonly390grams,The standard model is only 750grams,There is almost no sense of weight。 In addition, all three models have an IP67 waterproof rating, which is better than the Mini II.
 
It should be noted that due to the over-pure painting of the shell of this series, although the product is made of metal, the plastic feeling is still relatively serious, and it is definitely not cutting corners. The price of a single pocket model is 999 yuan, and the price span of other models is not large, only 3500 yuan can enjoy the shock of home theater in the room, you might as well give it a try.
