FIT & COMFORT
That said, fitment is a very personal metric to quantify, and every pair of ears is different. While the GripFit EarTips and Jackets provided a very secure fit, none of the various combinations I tried were particularly comfortable for me. The truly wireless design of the Zolo Liberty headphones means that each earbud needs to contain its own battery, Bluetooth radio, and other electronics, while the wire tethering the two Pixel Buds allows the left side to house the battery while the right holds the radio, touch sensor, and other electrical bits. The result is that the Liberty headphones are considerably bulkier and heavier than the Pixel Buds. I truly could forget that I was wearing the Pixel Buds, but I always felt the Libertys in my ears and often experienced a bit of soreness after extended listening sessions. Your mileage will likely vary, but the Pixel Buds are far more comfortable for me.
