Our Verdict
Sony WF-1000XM4 Truly Wireless
Bowers & Wilkins Pi7 S2 True Wireless
Depending on your preferences, you may enjoy either the Sony WF-1000XM4 Truly Wireless or the Bowers & Wilkins Pi7 S2 True Wireless. While both buds have a premium design and are decently comfortable, the Sony have a more customizable sound, a virtual soundstage support for a more immersive sound, and their battery performance is significantly better. However, the Bowers & Wilkins block out more ambient noise and their carrying case also doubles as a wireless transmitter.
