Hoco UPA21 Audio Adapter | 3.5mm Male to Dual 3.5mm Female | Nylon Braided (25cm)

The Ultimate Audio Sharing Solution: Hoco UPA21 (Male to 2x Female) Share the beat and double the fun with the Hoco UPA21 Audio Adapter Cable. In a world where we consume so much media on our personal devices—smartphones, tablets, and laptops—sharing that experience with a friend often means awkwardly sharing one pair of earbuds. The Hoco UPA21 solves this problem instantly by converting a single 3.5mm audio jack into dual 3.5mm female ports. This allows you to plug in two separate pairs of headphones or speakers into one device, making it the perfect accessory for couples, travel buddies, and collaborative workspaces.

Designed for Shared Entertainment Whether you are on a long flight wanting to watch a movie with your partner on one iPad, or sitting in the backseat of a car sharing a playlist with a friend, the Hoco UPA21 ensures both listeners get the full audio experience. Unlike simply sharing one earbud each (where you lose stereo separation), this splitter delivers full stereo sound to both sets of headphones. It is also an excellent tool for DJs or audio setups, allowing you to output a single audio source to two different external speakers or amplifiers simultaneously for a richer sound environment.

Premium Materials for High-Fidelity Sound Splitting an audio signal can sometimes lead to a drop in volume or quality if the cable is poorly made. The Hoco UPA21 is engineered to prevent this. It features a high-purity enameled copper wire core that ensures efficient signal transmission to both outputs. This design minimizes impedance and signal loss, delivering crisp, clear highs and deep bass to both connected headsets. The connectors are gold-plated to prevent oxidation (rust) and ensure a static-free connection, even after thousands of plug-ins.

Robust Aluminum and Nylon Construction Durability is a hallmark of the Hoco UPA21 series. The connector housings are made from a tough Aluminum Alloy. This metal shell protects the delicate solder points inside from being crushed or damaged if the cable is stepped on or dropped. The cable itself is encased in a premium nylon braided exterior. This woven fabric design is not only aesthetically pleasing but also highly functional—it resists pulling, bending, and the daily wear and tear of being tossed into a backpack. The braiding also prevents the cable from tangling, so you spend less time untying knots and more time listening.

The IDD Prime 1-Year Warranty Most audio cables on the market are cheap, disposable items that fail after a few weeks of bending. At IDD Prime, we offer a different standard. We stand behind the Hoco UPA21 with our exclusive 1-Year Warranty. If one of the audio channels fails, the jack becomes loose, or the sound quality degrades due to a manufacturing defect within 12 months, we will replace the unit brand new. This makes the UPA21 a safe and reliable addition to your tech travel kit.

Compact and Universal With a length of 25cm, the UPA21 is compact enough to carry in your pocket but long enough to provide flexibility between your device and your headphones. It is universally compatible with any device featuring a standard 3.5mm auxiliary port, including:

• Smartphones & Tablets: iPhones (with dongle), Samsung, iPads, Amazon Fire Tablets.

• Computers: MacBooks, Windows Laptops, and PC Towers.

• Media Players: MP3 players, Nintendo Switch, and portable DVD players.
