Choosing the right headphones is about balancing sound quality, comfort, cost, and portability. The number one reason why people turn away from in-ear earbud headphones is because they don’t like the invasive experience of shoving objects into their ear canal.

Passable for mixed usage. The Sony CH400 have a good audio reproduction that is versatile for a wide variety of music genres but their on-ear fit won’t be ideal for other use cases. They won’t block out enough ambient noise to be suitable for commuting and they’ll be too leaky for the office.

    Good audio reproduction., Remarkable wireless range., Good battery life.

  • -

    Long charging time., Flimsy and plasticky build., Very high latency.

I usually have a tough time when summing up my feelings and giving the verdict for a device. But the Sony WH-CH400 made things easy for me and I must say that I have been impressed with this device.
