"A cheap, waterproof, and secure earbud for workouts, with predictably basic audio quality."
'75H Playtime' refers to the total time available by repeatedly recharging the buds in the case, not continuous use. The more critical number, a claimed 15 hours per charge, is likely achievable only at very low, unrealistic volumes.
This is for someone who needs a low-cost, effectively disposable set of earbuds for the gym or running. The ear hooks provide a secure fit and the IP7 rating protects against sweat, which are the primary purchase drivers at this price.
Anyone seeking audio fidelity for music or podcasts should look elsewhere, as the drivers and tuning will be rudimentary. Those needing true active noise cancellation for commutes or noisy environments will find none here.
