Built for Workouts
The earbuds use an ergonomic ear-hook that wraps around the ear, which helps prevent slipping during running, gym sessions or cycling. Soft silicone ear tips are described as sweat-resistant and skin-friendly. HAMMER’s founder said the KO2 is designed for people who “don’t want their earbuds getting in the way of their workout”, which sums up the focus on a secure fit.
Sound and Noise Cancellation
A 13mm titanium dynamic driver handles audio, and the earbuds offer up to 25dB of active noise cancellation with four MEMS microphones. At this price, ANC is more about reducing steady background noise, such as a gym’s hum or road noise, than the strong isolation of premium models. The four microphones also help with call clarity. Bluetooth 6.0 is the latest standard, which promises stable connections and efficient power use.
That 80-Hour Number
Up to 80 hours of total playtime at 50 percent volume is impressive, though it includes charges from the case and depends on conditions. With ANC on and the volume higher, you will get less. Even so, it suggests you may need to charge only once in a week of typical use. A full charge takes under two hours through USB Type-C, with fast charging supported.
Where You Can Buy and What to Watch
The earbuds are sold on HammerOnline.in, Flipkart, Blinkit, Swiggy and Amazon.in, so even quick-commerce apps carry them. The warranty is six months, which is shorter than some rivals offer, so keep your invoice. We have not tested the earbuds, so sound quality, ANC strength, comfort and the accuracy of the playtime claim are unconfirmed. Also note that no water resistance rating was listed in the details we reviewed, so avoid heavy rain and wash the ear tips rather than the earbuds.
For the brand background, see the HAMMER website and read about the connection standard on Wikipedia. More budget audio launches are under our earbuds tag.

Who Should Buy Budget Sports Earbuds?
Budget ear-hook earbuds make sense for people who want a secure fit for runs and workouts without spending on premium brands. They are also a sensible spare pair, since losing a ₹1,299 set hurts far less than losing an expensive one. Students, delivery riders and anyone who commutes on busy roads may appreciate the long battery life.
The compromises are the ones you would expect: sound may be less refined than pricier earbuds, ANC will be modest, and support and warranty can be limited. Before buying, check how the ear-hook feels over an hour, since comfort matters more than specs for sports earbuds. Try them with glasses or a helmet, and check how the touch controls respond with sweaty fingers.
Treat the 80-hour claim as a best-case figure, and look for user reviews after a few weeks to see whether the real battery life and connection stability match the promise.
