The JBL Tune 230NC TWS earbuds feature 6.0mm drivers. These drivers are responsible for producing the sound you hear when listening to music or other audio.
The size of the driver can influence the overall sound quality of the earbuds. Larger drivers tend to produce more powerful bass and a wider frequency response, while smaller drivers might offer more clarity and detail in the higher frequencies.
While the specific sound signature of the JBL Tune 230NC is influenced by several factors beyond just the driver size, the 6.0mm drivers are a key component in delivering JBL's signature Pure Bass Sound.
