Comparison · updated 2026-10-08
Two lower-priced rings, separated by fit, charging and an existing watch ecosystem.
Gen 2 Air is the broader budget shortlist; Helio is worth considering for existing Zepp users who fit sizes 8, 10 or 12.
Gen 2 Air offers more sizes and the longer manufacturer battery estimate. That makes it easier to shortlist for a first ring, even though its dock needs external power. It does not depend on owning a particular watch, and the core tracking has no mandatory plan.
Helio can be a useful addition if you already use Amazfit and want overnight data inside Zepp. Its lower reference price is attractive only once fit and a real local seller are confirmed. It is not a universal budget recommendation because the three-size range excludes many fingers.

Reference costs use dated hardware prices and full required monthly payments; introductory months, annual discounts, taxes, shipping and optional services are excluded. Battery figures are manufacturer claims, not our tests.
Try the sizing samples rather than choosing the nearest available number. Compare checkout prices in the same currency; the USD table is not a local price promise. If your Amazfit watch is comfortable at night and already supplies the trends you use, Helio may duplicate data instead of solving a problem.
Confirm market, phone, size and required plan first. A product that fails one is not a match.
Battery and feature claims come from different test conditions. Read each product page’s dated sources and evidence note.
