The Sennheiser CX 6.00BT scores well on specifications and looks good on paper, but the sound quality has considerable room for improvement.

I was recently at a Christmas party when I asked my friend who oversaw the equipment whether I could play some music over the speaker system. "Of course," my friend replied. "It is all yours after this song." A few minutes later, I dropped by the booth again as he moved aside to hand me control of the station. When I picked up the cord with the 3.5mm auxiliary audio jack to plug it into my phone, I quickly realized I forgot something. "Actually, I cannot DJ anything," I said. "I have an iPhone X." My friend laughed as he switched the input back to his device. Ever since the birth of the iPhone 7, there has been considerable controversy in the consumer world on whether the removal of the headphone jack was justified or not. For me personally, I argued it was a good thing; we cannot stick to legacy technology forever instead of moving on to more convenient industry-standard interfaces like Bluetooth. Even when I had an iPhone 6, I rarely used the 3.5mm jack. For headphones, I used the excellent V-MODA Crossfade Wireless and later, the Crossfade II Wireless. In the rare occasions I used earphones, I used the Focal Spark Wireless. Thanks to Apple's push of wireless technology in their phones, more audio manufacturers are producing Bluetooth earphones. As such, today, we have yet another set of wireless earphones in our labs. The Sennheiser CX 6.00BT is the company's latest addition to their vast portfolio of audio products for about $100 at press time. How will it compare to other similar priced in-ear monitors like the Focal Spark Wireless? Read on to find out!
