# Monster AC520 E93 Open-Ear True Wireless Headphones

Monster AC520 E93 open-ear headphones are true-wireless earbuds with touch controls and a charging case. The listing claims up to 8 hours per charge and 24 hours with the case, while another detail gives a general 24-hour battery-life figure. Their open-ear format is intended for listening while remaining aware of nearby sounds, rather than isolating you from ambient noise.

## At a glance

- Open-ear design lets ambient sounds remain audible during listening, according to the listing.
- The feature description claims up to 8 hours on one charge and up to 24 hours with the charging case.
- A slide-open case design and removable lanyard are described in the feature copy.
- Bluetooth connection and touch controls are listed.

## Pros

- Open-ear placement suits listeners who want to hear nearby conversations and environmental sounds while listening.
- A charging case and Type-C charging cable are listed in the package contents.
- The listing describes touch controls and a built-in microphone for calls.

## Cons

- Open-ear placement does not provide the passive isolation of sealed in-ear headphones, so surrounding noise can compete with audio.

## Before you buy

- Battery details are inconsistent: a general specification says 24 hours, while feature copy says up to 8 hours on one charge and up to 24 hours including the case. The listing also claims IPX6 water resistance and sweat/rain use, but the water-resistance field says Not Water Resistant. Confirm the intended protection rating and runtime conditions for the selected listing before relying on either claim.

## A good fit for

- Listeners who prefer an open-ear design that keeps nearby sounds audible.

## Less suited to

- Listeners who need noise isolation or dependable blocking of surrounding sound.
- Buyers who need an unambiguous water-resistance rating or battery-runtime specification.

## Customer feedback

The supplied evidence contains only aggregate ratings, with a very small rating sample and all recorded ratings in the five-star category. That offers little detail about fit, call quality, sound, or the conflicting battery and water-resistance claims, so it is not enough to establish how the headphones perform in those areas.

## Frequently asked questions

### How long does the battery last?
The feature description claims up to 8 hours from a charge and up to 24 hours with the charging case. A separate specification lists 24 hours without explaining the operating conditions, so treat runtime as unclear.
### Are these headphones water-resistant?
The listing conflicts: feature copy claims IPX6 resistance and use in sweat or rain, while the technical water-resistance field says Not Water Resistant. Confirm the rating before using them around water.
### Do they block outside noise?
No noise-control feature is listed, and the open-ear design is described as allowing surrounding sounds to be heard. They are not presented as noise-isolating headphones.
### What comes in the package?
The package list names the headphones, one Type-C charging cable, a user manual and a wireless charging case.
