Sony WH-CH700N vs WH-CH510 Wireless

The Sony WH-CH700N Wireless are better headphones than the Sony WH-CH510 Wireless, but with a different design. The CH700N are over-ears that are a bit bulkier but are more comfortable, while the CH510 are slightly smaller and more portable thanks to their on-ear design, but aren't nearly as comfortable. The CH700N also look and feel better-built, feel more stable on the head, have a better-balanced sound profile with more low-bass, and have a dedicated companion app with a graphic EQ and presets. On the other hand, the CH510 breathe better, are much more consistent among different users, and have slightly longer battery life.
