JBL - Live Beam 3 vs Nothing - Ear (a) 2

These two are nearly even on the Mars Score (76.1 vs 74.5). The decision isn't about overall quality — both clear the bar — it's about which specific trade-offs fit your use.

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. The biggest gaps in its favor are battery — buds, battery — with case, spatial audio, among others.

Pick the Ear (a) 2 if you care most about driver size and weight per bud. Its strongest claims are driver size, weight per bud.

Both ship with comparable active noise cancellation, multipoint, so those specs don't separate the two — focus on the differences below.

Bottom line: there is no wrong answer here — match the spec advantages to how you actually use the product. The Mars Score parity tells you both are well-rounded; the differences are about trade-offs, not quality.
