ROSFO is a personal audio brand founded in Wyoming, United States, and operated by ROSFO LLC. We focus on open-ear bone-conduction headphones, Bluetooth listening devices and personal sound amplification products for everyday use. Our purpose is straightforward: give people a practical choice in how they listen, with clear product information and support after the purchase.
Sound belongs in everyday life
A favorite song while getting ready. A voice across the kitchen table. A phone call on the way home. Personal sound is part of ordinary moments, and the product carrying it should feel understandable and easy to live with.
Some people simply do not like placing an earbud inside the ear canal. Others want accessible controls or a headset that leaves their ears unsealed. We built ROSFO around those practical preferences. We want choosing an audio product to start with your routine and the way you prefer to wear it.
What makes our approach different?
G1001, G1002 and G1003 use an open-ear, wraparound bone-conduction design. The listening pads rest beside the ears; no earbud tips are inserted into the ear canals. That means there is no ear-tip contact or pressure inside the canal. Fit and comfort remain personal: the headset still touches the outside of the head, and it should feel comfortable at those contact points.
Leaving the ear canals unsealed also leaves a path for everyday sounds alongside your audio. It does not guarantee that you will hear every warning or conversation. We encourage comfortable listening levels and attention to your surroundings.
A small range with meaningful choices
- G1001: indoor and outdoor modes, Bluetooth connectivity and USB-C charging.
- G1002: Bluetooth music and calls, on-device controls and magnetic charging.
- G1003: independent left/right volume, three modes and five levels, with USB-C charging.
- D800: a single-ear model with spoken volume prompts and USB-C charging. Check the product page for current availability.
We describe each model's controls, charging and estimated playback separately. More expensive is not automatically the right choice for every routine. Our model comparison and bone-conduction buying guide help you compare the differences that matter.
The people and capacity behind the products
Our manufacturing partners operate factory space spanning thousands of square meters. Across our sound product range, tens of thousands of units have been sold worldwide. Those are responsibilities as much as milestones: every product needs understandable information, a way to obtain help and a clear process when something is not right.
ROSFO LLC operates the online store at rosfoglobal.com. Our public contact information and legal notice identify the store operator, and our support team can help with model, order and aftercare questions.
Care continues after checkout
You can request a return or exchange within 30 days of delivery. Non-faulty returns must remain in resalable condition, and return shipping responsibilities are explained in our return policy. Contact us before sending a device back so we can provide the correct instructions and address.
Optional one- or two-year replacement cover is a separate paid service for a matching device. It includes one eligible replacement during the selected term after the original device is returned, subject to the cover terms and exclusions. We make those distinctions visible so you can understand what you are choosing.
Less unnecessary packaging. More thought after use.
We reduce unnecessary packaging, use recyclable materials and recover original devices returned through our replacement process for recycling. Recycling options vary by material and location; local guidance determines how packaging and devices can be handled. These are practical steps we take, with room to keep improving.
Clear about what ROSFO products are
ROSFO products are consumer audio and personal sound amplification products, not medical hearing aids. A non-in-ear fit describes how the product is worn; it does not establish treatment, disease prevention or suitability for a particular hearing condition. If you are choosing because of hearing difficulties, read our hearing questions guide and seek advice appropriate to your hearing needs.
