Earbuds that reviewed brilliantly and then developed a reputation. Battery failure reports — often just after warranty — are extensive enough to be the defining feature of owning them.
This entry is written from the 5 sources listed at the bottom of the page. The numbers are our editorial estimates drawn from that material, not measurements, and no statistical sample sits behind them.
The pattern in the sources is regret. Only 39% of owners say they would buy it again, and satisfaction falls from 9.0 to 5.4 out of 10 by the two-year mark.
This is roughly where the reports begin. Sound and comfort stay excellent; the risk is that the battery collapses somewhere between year one and year two.
Sudden battery drain is the single most documented long-term issue. Teardown communities confirm the cells are not practically serviceable. Owners describe losing a premium pair just outside the warranty window.
It is a real product that works, but its launch reception (80 out of 100 for hype) ran well ahead of how owners feel about it later. Sudden battery drain is the single most documented long-term issue. That gap is what the regret score measures.
Worth it for: Buyers finding them heavily discounted and accepting the risk; People who want the sound above all; Anyone with extended warranty cover. Think twice if: You want earbuds to last three years; You'd be angry at a failure just out of warranty; You want a repairable product.
