If you want a versatile 2-in-1 adapter that lets you listen to music and charge your phone simultaneously while traveling, choose Subynanal USB c; if you need a specialized, durable magnetic charging cord specifically designed for Ortizan i10 bone conduction swimming headphones, choose WUNIAK Charging Cable.
• Subynanal USB c: Delivers simultaneous audio playback and fast charging up to 60W with high-fidelity support (32-bit/384kHz), but it cannot transfer data and is limited to specific wired headphone configurations.
• WUNIAK Charging Cable: Offers a secure, flexible magnetic connection with built-in voltage regulation to protect delicate electronics, though it is strictly a replacement charger for one specific headset model and not a universal adapter.
• Who it's for: The Subynanal is the go-to solution for iPhone and Android users who refuse to let their battery die during long flights or commutes. The WUNIAK is an essential backup for swimmers and athletes who own the Ortizan i10 and need a reliable, tangle-free power source.
This adapter is engineered for the traveler who refuses to compromise between staying connected and keeping their device powered. If you have ever sat in a cramped airplane seat trying to navigate a dead battery while listening to a movie or podcast, this 2-in-1 dongle solves that exact problem. It combines a USB C Power Delivery 3.0 port with a standard 3.5mm aux jack into a single, compact unit. The design allows you to plug in your preferred headphones and connect to a power source at the same time, ensuring you can control volume and take calls without interruption.
The technical specifications here are particularly impressive for a small accessory. It supports high-resolution audio up to 32-bit and 384kHz, which is significantly higher than the typical 24-bit and 96kHz found in many generic competitors. This means if you are using high-quality wired earbuds or over-ear headphones on your phone, the sound fidelity remains crisp. Furthermore, the fast-charging capability handles up to 60W of power, making it compatible with PD wall chargers to refill your battery quickly during layovers or short trips. It is widely compatible with the latest flagship devices, including the iPhone 17, 16, and 15 series, as well as Samsung Galaxy S24 and S23 models, Google Pixels, and various iPad Pros.

However, this product is not a magic wand for every situation. It does not support data transfer; the USB-C port is dedicated solely to charging. You also need to be aware that while it supports CTIA and OMTP standards, it may not support Quick Charge (QC) protocols on some newer phones unless paired with a specific PD wall charger. Additionally, the line control features work for most headsets but exclude Apple's proprietary headphones. If you are looking for a cable to move files between your computer and phone, or if you rely exclusively on wireless earbuds without a backup plan, this adapter might not be the right fit for your daily routine.
In contrast to the multi-purpose nature of the Subynanal, the WUNIAK Charging Cable serves a very specific, critical niche: replacing the power source for the Ortizan i10 Bone Conduction Swimming Headphones. This is not a general-purpose cable you would use for a smartphone or tablet. Instead, it is a precision-engineered accessory designed to ensure your swim gear stays powered up safely. The cable features a magnetic connector, which is a game-changer for active users. Whether you are drying off by the poolside or packing up after a workout, the magnetic connection ensures you don't fumble with tiny ports in wet or awkward conditions.
Durability and safety are the core strengths of this product. Inside the cable, there is a Voltage Regulator (PTC) that acts as a safeguard against overcurrent. This is crucial for protecting the sensitive internal components of your bone conduction headphones from damage caused by unstable power sources. The cable itself is made from copper wire and is designed to be flexible, measuring 60cm in length. This size makes it easy to stash in a gym bag, a car console, or a carry-on without taking up much space. The black design is sleek and unobtrusive, fitting seamlessly into an athlete's gear collection.
You should only buy this if you already own the Ortizan i10 headphones and have lost or damaged your original charger. It is sold as a 2-pack, which offers excellent value for someone who keeps a charger at home and another in the car or at the office. However, if you do not own the specific Ortizan i10 model, this cable is useless to you. It will not fit any other device, including smartphones, tablets, or other brands of headphones. It is a single-function tool built for reliability and convenience within a very narrow ecosystem of compatible devices.
• Best for airplane travel: Subynanal USB c. Its ability to charge and play audio simultaneously makes it ideal for long-haul flights where you want to conserve battery life without sacrificing entertainment.

• Best for audio quality: Subynanal USB c. With support for 32-bit/384kHz resolution, it delivers superior sound clarity compared to standard adapters when used with high-end wired headphones.
• Best for convenience: WUNIAK Charging Cable. The magnetic snap eliminates the frustration of aligning pins in the dark or while hands are wet, offering a smoother user experience for its target audience.
• Best for data needs: Neither. Both products are focused on power and audio; neither transfers data files between devices.
• Best for budget-conscious travelers: Subynanal USB c. While pricing varies, its dual functionality replaces the need to carry two separate items, offering more utility per dollar spent for general consumers.
For the average consumer navigating modern travel, especially for airplane trips, I would choose the Subynanal USB c. The ability to keep a phone charged while listening to music or podcasts is a necessity rather than a luxury these days, and the high-resolution audio support adds genuine value for audiophiles. It solves a universal pain point for anyone with a USB-C device who still prefers wired headphones or needs a backup audio option. In my opinion, the WUNIAK cable is a fantastic, specialized tool, but it is too niche to recommend to the general public unless you are already an owner of the Ortizan i10. For everyone else, the Subynanal adapter is the practical, reliable choice that keeps you connected and entertained wherever you go.
