Sennheiser is one of the leading brands of high-performance HiFi headphones, but there are not many headphones for the sports market, and there is no other than the various 686 series. During CES 2018, Sennheiser finally unveiled the new sports headphones CX Sport, which is similar to its own Bluetooth headset CX6.00BT, adding the classic fluorescent yellow color of the 686 series.
 
The CX Sport received a high score of 71 points in the U.S. Consumer Reports, tying for second place in wireless sports headphones. Its configuration is gorgeous, supporting aptX and AAC Bluetooth encoding, and it has a good sense of hearing. The CX Sport's low-end dive is deep, layered but not dominant, the midrange vocals are prominent and full, the atmosphere is obvious, and the accompanying instruments surround the orderly, and the sound quality is very rare in sports headphones. However, Consumer Reports also pointed out that it has a more pronounced stethoscope effect.
 
Elsewhere, the CX Sport is rear-mounted, weighs only 15g, and has shark fins for a comfortable and secure fit. The battery life is 6 hours, although it is not long, it only takes 1.5 hours to charge, and it supports a fast charging function of charging for 10 minutes and listening to songs for 1 hour. CX Sport can also connect two devices at the same time, but it only supports waterproofing and is priced at 899 yuan.
