Page 4 - Conclusion
By specifications alone, the Sennheiser CX 6.00BT is very competitive in the realm of wireless in-ear monitors. It has decent, understated looks with reasonably good build quality, and its necklace-style wireless design is balanced and lightweight. It fits well in my ears, and should be no different for the majority of the population thanks to the inclusion of four different sized sets of ear sleeves. On the wireless side of things, the Sennheiser CX 6.00BT has Bluetooth 4.2 with aptX and aptX LL support; combined with a well-designed antenna means you can be assured you will get a lag and interference-free usage experience. The tested battery life of just over seven hours will deliver a whole day of music enjoyment before the need to reach for the plug. However, when it comes to sound quality, the Sennheiser CX 6.00BT leaves quite a bit to be desired. It features a fun V-shaped frequency response with strong bass output and an acceptable midrange, but was pulled back by its messy treble and narrow soundstage. The overall smoothness and cohesiveness of sound also has lots of room for improvement. Other minor suggestions for improvement include using a USB-C rather than Micro USB port for charging, remote with more responsive and tactile buttons, and a real carrying case rather than counting the packaging as one. With the CX 6.00BT added to Sennheiser's latest addition to their vast portfolio of audio products for about $100 at press time, how did it compare to other similar priced in-ear monitors like the Focal Spark Wireless? Considering the shortcomings in sound quality, in my opinion, you are better off buying the Spark Wireless for the same price. As an added bonus, you will get more than one color choice, too.
