どちらを買うべき?
The Live Beam 3 is the clear pick on raw spec strength, leading by 17.7 points on the Mars Score. The margin is wide enough that the underdog only makes sense if its individual strengths line up with what you specifically need.
The QuietComfort Earbuds (II) doesn't pull ahead on any single popular-comparison spec — its strengths sit in the spec table groups rather than the headline advantages.
Pick the Live Beam 3 if your top frustration with your current device is running out of charge before the day ends — endurance is the lead spec here. Its strongest claims are battery — with case, battery — buds, driver size, among others.
Both ship with comparable active noise cancellation, so those specs don't separate the two — focus on the differences below.
Bottom line: the Live Beam 3 is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
