# MJOFFIN x20s Bone Conduction Open-Ear Headphones, Bluetooth 5.4

MJOFFIN x20s bone conduction headphones use an open-ear design intended to leave your ears uncovered while listening. The listing claims a 22 g weight, Bluetooth 5.4 and up to 10 hours of playtime, making them a lightweight option to consider for outdoor activity. The page describes IP55 protection, while the technical details state only “Water Resistant,” so treat the precise protection rating as unconfirmed.

## At a glance

- Open-ear design is intended to let users hear surrounding sounds while listening.
- The listing claims up to 10 hours of continuous playtime and talk time on a charge.
- The feature description claims a noise-reduction microphone for calls.
- A flexible titanium frame and compatibility with glasses and helmets are claimed in the feature text.

## Pros

- Open-ear fit avoids placing an earbud inside the ear canal and may suit listeners who want to remain more aware of their surroundings.
- The listed 22 g weight is a concrete consideration for buyers prioritizing a light headset.
- The claimed 10-hour playtime and Bluetooth connection suit untethered listening during workouts or walks.

## Cons

- Open-ear listening does not isolate the listener from surrounding sound, which may be a poor fit where audio isolation is the priority.

## Before you buy

- The listing details are inconsistent on water protection: the title and feature text claim IP55, but the technical details state only “Water Resistant.” The feature text also claims a flexible titanium frame while the materials field lists plastic. The microphone is described as noise-reducing in the title and feature text, while the noise-control field says “None.” Confirm the exact rating, materials and microphone behavior before relying on those claims. Open-ear use does not guarantee awareness of hazards, so stay attentive during outdoor activity.

## A good fit for

- Runners, walkers and cyclists considering open-ear listening while keeping their ears uncovered.
- Buyers looking for a lightweight wireless headset for workouts or phone calls.
- People who want a frame-style fit that the listing says can work with glasses or helmets.

## Less suited to

- Listeners who need ear-sealing noise isolation or privacy in noisy environments.
- Buyers who require a confirmed waterproof rating for swimming or immersion.

## Customer feedback

Customer feedback highlights sound quality, lightweight wear and outdoor use. Those comments align with the open-ear, 22 g design as considerations for walking and workouts, but do not establish a particular water-protection rating or confirm swimming suitability. The overall rating distribution is mostly five-star but includes three-star and one-star ratings, so experiences are not uniformly positive.
- Positive themes: Customers mention sound quality and lightweight wear.
- Positive themes: Feedback mentions outdoor use and hearing surroundings while listening.
