Between the LinkBuds Open and Ear (3), the LinkBuds Open comes out ahead in spatial audio, while the Ear (3) wins on battery — with case and battery — buds. Overall, the LinkBuds Open scores 69.5 and the Ear (3) scores 70.8 on our Mars Score.
Which should you buy?
These two are nearly even on the Mars Score (69.5 vs 70.8). The decision isn't about overall quality — both clear the bar — it's about which specific trade-offs fit your use.
Pick the LinkBuds Open if audio quality and feature breadth (ANC, codecs, multipoint) are the lead criteria for your purchase. The biggest gaps in its favor are spatial audio.
Pick the Ear (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, active noise cancellation, among others.
Both ship with comparable driver size, 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.
