wireless earbuds with the longest lasting battery

If your top priority is the longest battery life, look at hours per charge (the earbuds themselves) rather than the often-advertised “total hours” that include the charging case.

JLab Epic Sport ANC 3 Varies by mode Up to 52+ hours Gym use + huge case capacity
Soundcore Liberty 4 NC Around 10 hours without ANC Up to 50 hours Long battery + ANC on a budget
If you want the absolute longest single charge

Top pick: Soundcore P41i — among the highest advertised earbud-only runtimes, with up to 12 hours per charge.

For sleeping, flights, or all-day listening, prioritize earbud-only runtime rather than case totals.

Best “premium but still long-lasting”

Beats Powerbeats Pro 2 — excellent if you move around a lot because the ear-hook design keeps them secure while delivering strong battery life.

Sennheiser MOMENTUM True Wireless 4 — better if sound quality matters more than having the absolute longest runtime (up to about 7.5 hours per charge, 30 with case).

My shortlist:

Longest battery overall: Soundcore P41i

Best for workouts: Beats Powerbeats Pro 2

Best value long battery + ANC: Soundcore Liberty 4 NC

Best sound among long-life options: Sennheiser MOMENTUM True Wireless 4

If you mean longest battery with ANC turned on, the ranking changes quite a bit.
