Does the Monster Open Ear AC210 have active noise cancellation?

No. It is an open-ear design that lets ambient sound in by design; the noise-canceling spec label is misleading. It is meant for awareness, not isolation.

How long does the battery last?

Monster claims up to 30 hours of total playback with the charging case. Expect a few hours per charge in the earbuds themselves, less at high volume.

Is it good for running and rain?

Yes for sweat and light rain, thanks to the IPX5 rating. Do not swim or submerge it, and dry the hooks after heavy workouts.

The earbuds, the charging case and a USB-C charging cable. A wall adapter is not included.

Is $16.99 a good price?

Yes. At $16.99 at Walmart as of November 6, 2026, it is near the bottom of its recent range and among the cheapest open-ear headsets available.

How does it compare with bone-conduction headphones?

It is cheaper and gives fuller sound than most bone-conduction models, but bone conduction leaks less and stays more secure for hard running.

Our take on the Monster Open Ear AC210 Headphones

The Monster Open Ear AC210 is a budget open-ear Bluetooth headset that hooks over the ear instead of sealing into the canal, so you stay aware of traffic, coworkers and surroundings. It pairs over Bluetooth 5.4, claims 30 hours of total playback with the charging case, and charges over USB-C. It has touch controls, a built-in mic for calls and an IPX5 water-resistance rating. At $16.99 at Walmart as of November 6, 2026, it sits at the low end of its recent price range and is one of the cheapest open-ear options on the market.
