The LinkBuds Fit can be seen as an evolution of Sony’s LinkBuds S. Like the older models, these are wireless, noise-canceling earbuds with a few adjustments. Most importantly, Sony designed its new earbuds to be more comfortable. The company told us it made the casing shorter and covered it with a “silicone supporter.” Inside this silicone is an air cushion.

The ANC feature blocks varying amounts of sound, depending on the environment. I heard more ambient sound in my quiet room, like the traffic outside my window. At the gym, things were much quieter. I could hardly hear the weights being slammed down or the music from the speaker system. This auto-optimizer feature really impressed me.

Sony says the earbuds last 5.5 hours on a single charge by themselves, and 25 hours with the case. During my testing, I managed to get the earbuds to run for almost seven hours before I needed to grab the charger. I had ANC turned on, and was playing music at a low volume, so extending the runtime with a few tweaks is possible.
