Roseselsa OpenFree

Name: Roseselsa OpenFree
Brand: Roseselsa
SKU: 4522

Manufacturer: Roseselsa

The Roseselsa OpenFree are true wireless earbuds built around an open-ear fit, making them a practical choice for listeners who prefer to stay aware of their surroundings while enjoying audio. With no wires or cables and a compact charging case included, the design leans toward everyday portability. The earbuds carry an IPX4 sweat-resistance rating, and a travel bag is included in the box. Stereo playback is supported, and voice prompts help with general device interaction.

On the connectivity side, the OpenFree runs on Bluetooth 5.4 with a stated maximum range of 10 meters, and supports both LDAC and LDHC high-resolution audio codecs alongside AAC. Audio latency is listed at 20 ms, and multipoint connection allows pairing with two devices simultaneously. The 10 mm drivers cover a frequency range of 20 Hz to 20,000 Hz, with an impedance of 32 Ohms. Battery life stands at 10 hours per charge with a 45 mAh cell, backed by a 500 mAh charging case offering an additional 42 hours — and fast charging is supported via USB Type-C with a full charge taking around 2 hours. A noise-canceling microphone is built in, and the earbuds can function as a headset with mute capability.

Pros

Open-ear fit allows users to remain aware of their surroundings while listening
Supports both LDAC and LDHC codecs, enabling high-resolution audio streaming
Multipoint connection lets the earbuds stay paired to two devices at once
The charging case provides a total of 42 hours of combined playback, extending usage between full recharges
Fast charging is supported, reducing downtime when the battery runs low
A noise-canceling microphone is included, improving voice clarity during calls

Cons

No active noise cancellation or passive noise isolation, leaving users fully exposed to ambient sound
Wireless charging is not supported, requiring a cable for every recharge
No in/on-ear detection, so music will not pause automatically when the earbuds are removed
Ambient sound mode is absent, offering no software control over environmental audio passthrough
No find-device feature, making it harder to locate misplaced earbuds
Bluetooth range is limited to 10 meters, which may be restrictive in larger spaces

Who is this for?

These earbuds are a practical fit for users who prioritize situational awareness — such as outdoor runners, cyclists, or commuters — where an open-ear design keeps them connected to their environment. The LDAC and LDHC codec support makes them a reasonable choice for listeners who stream high-resolution audio and want to preserve audio quality over Bluetooth. Users who frequently switch between two devices will also appreciate the built-in multipoint pairing, and the included travel bag alongside the 42-hour total battery capacity suits those who need a reliable daily companion without frequent charging stops.

Who is this NOT for?

Users who need noise isolation or active noise cancellation — such as those working in loud offices, on planes, or in busy public spaces — will find the open-ear design and complete absence of any noise-reduction technology a significant drawback. The earbuds are equally unsuitable for those who rely on ambient sound mode for controlled audio passthrough, or who want in/on-ear detection to automatically pause playback when removed. Additionally, users operating across larger spaces or requiring extended wireless freedom may find the 10-meter Bluetooth range limiting in practice.

Final Verdict

The Roseselsa OpenFree carve out a clear niche as open-ear true wireless earbuds built for users who value environmental awareness without sacrificing audio quality. The combination of LDAC and LDHC codec support alongside Bluetooth 5.4 gives the earbuds a meaningful edge for high-resolution wireless listening, and practical touches like multipoint pairing, fast charging, and a 42-hour total battery capacity strengthen their case as a dependable daily option. That said, the absence of any noise isolation or cancellation and the open-ear architecture make them a poor match for noisy environments. For the right user — one who needs to stay aware of their surroundings while enjoying quality audio — the OpenFree deliver a focused and coherent feature set worth considering.
