Introduction

The Otium Bluetooth Earbuds are a set of wireless neckband-style earphones designed for sports and everyday audio use. Marketed for activities like gym workouts and running, they emphasize a secure fit, water resistance, and extended battery life. The product is identified as the latest upgraded version of the Otium line, and it now operates under the Bluetooth device name “U18” for easier pairing. This review covers the key features and specifications as presented in the product information.

Product Overview

These earbuds use a neckband design, which the manufacturer states prevents troublesome wires from tangling during exercise. The earphones feature rubber ear hooks that are designed to fit the curve of the human ear, aiming to provide a secure and comfortable fit. The product is built around Bluetooth 5.3 technology and includes a built-in microphone for handling calls. The primary focus of the design is to support active use, with specific attention to water resistance and battery longevity.

Features and Specifications

The Otium earbuds come with a straightforward set of features aimed at sports use and daily connectivity. Below is a summary of the stated specifications:

• Bluetooth Version: The headphones utilize Bluetooth 5.3 technology.
• Waterproof Rating: The device has an IPX7 waterproof rating, which the manufacturer states provides resistance to water, splashes, and sweat.
• Battery Life: The lithium polymer battery is stated to provide up to 16 hours of music playtime and up to 240 hours of standby time.
• Charging Time: A full charge is stated to take approximately 1.5 hours.
• Wireless Range: The headphones can connect to devices up to 30 feet (10 meters) away.
• Control: The unit features a one-button control system for music and phone functions.
• Microphone: A built-in microphone is included for call handling.

Design and Connectivity

The design centers on a neckband form factor with ear hooks made of high-quality rubber. According to the product information, these hooks are specifically shaped to match the curve of the human ear, which is intended to help the earbuds stay in place during movement. The manufacturer states that the earbuds will “never fall out,” though this is a claim regarding the design intent rather than a guarantee of performance.

In terms of connectivity, the headphones are described as providing a steady connection without dropouts. Pairing is simplified by the upgraded Bluetooth name “U18,” which the manufacturer notes makes it more convenient to search and connect. The product supports multi-point connection, allowing users to connect two smartphones at the same time. The stated process for doing so is as follows:

• Pair with the first device.
• Turn off the Bluetooth on the first device.
• Pair with the second device.
• Turn the Bluetooth back on for the first device.

Once completed, both devices should show as connected to the headphones.

Audio and Communication Features

The product information highlights “True HD High Fidelity Sound,” referencing the Bluetooth 5.3 technology and improved acoustic components. The stated sound profile includes deep bass and crystal-clear treble. While these are descriptive claims from the manufacturer, they outline the intended audio focus of the device.

For calls, the built-in microphone is designed to reject surrounding noise, with the goal of keeping the user’s voice clear during conversations. Additionally, the headphones incorporate “Sound Isolation Technology” and noise suppression technology intended to reduce background noise, allowing the listener to focus on audio content. The product information does not specify active noise cancellation; the described feature is sound isolation and noise suppression for calls and listening.

Usage and Compatibility

The Otium earbuds are positioned for use in active environments, specifically gym workouts and running, due to their IPX7 waterproof rating and secure fit design. The IPX7 rating indicates the device can withstand immersion in water up to 1 meter for 30 minutes, though the product information specifically mentions resistance to splashing water, rain, and sweat.

For operation, the one-button control allows users to skip, play, and pause music tracks, as well as manage phone functions without reaching for the connected device. The battery status is visible on the connected phone, and a low battery voice notification alerts the user when power is running out. The headphones are compatible with all Bluetooth-enabled devices, at least within the stated 30-foot range.

Product Configuration

There are a few specific configuration details worth noting. First, the product does not have the “Otium” logo printed on it. The manufacturer explains this is intentional, as the latest upgraded version omits the logo to improve the customer experience, though the brand remains Otium.

Second, the device includes a reset function. To restore factory settings, the user should long-press the Multi-Function Button (MFB) for approximately three seconds while the device is charging. A successful reset is indicated by the red and blue LED flashing three times.

Finally, the product is backed by a 1-year manufacturer’s warranty and a 60-day no-questions-asked money-back return policy.
