Our Verdict
Bose QuietComfort Ultra Earbuds Truly Wireless
Sennheiser MOMENTUM True Wireless 4
The Sennheiser MOMENTUM True Wireless 4 and Bose QuietComfort Ultra Earbuds Truly Wireless have much in common, like their similar battery lives. Both earbuds support aptX Adaptive, including aptX Adaptive (Low Latency). The Sennheiser sound is less excited in the lows and they also have dust resistance with an IP54 rating, instead of just water resistance on the Bose's IPX4 rating. However, they're not as comfortable as the Bose, which reduce more low-pitched noise. And only the Bose earbuds include virtual surround sound.
