If you want a dedicated, multi-port hub to keep your phone charged while using both wired and wireless headphones simultaneously for movies, choose caojunzhen 1; if you need a reliable, durable 2-pack solution with superior portability and consistent audio performance for long flights or commutes, choose esbeecables USB C.
• caojunzhen 1: Its biggest strength is the unique "one-to-three" design that splits a single port into two headphone outputs plus a charging slot, but its trade-off is a heavier build focused on stationary use rather than travel. This pick is for the home theater enthusiast who wants to share audio or switch between gear without unplugging.
• esbeecables USB C: Its biggest strength is the rugged aluminum construction and the inclusion of a second unit in the box for backups, though it only offers a single audio path at a time. This pick is for the frequent traveler and commuter who needs a lightweight, fail-safe adapter that fits easily in a pocket.
• Both devices deliver high-fidelity sound, but they solve different connectivity problems: one focuses on multiplexing ports, while the other focuses on durability and redundancy.
The caojunzhen 1 stands out immediately because it does not just split your connection; it expands it. Most adapters force you to choose between listening to music and charging your device. This unit goes further by giving you three distinct outputs from a single USB-C port. You can plug in a USB-C headset for gaming, connect traditional 3.5mm wired headphones for movies, and still have a PD charging port active all at once. This specific configuration makes it an ideal companion for kids headphones for movies in a living room setting, where you might want to pass one set of earbuds to a child while keeping your own wired pair connected, or simply charge your tablet while watching content on a couch.
The internal architecture of this adapter supports a robust DAC capable of handling 16-bit/192kHz or 24-bit/96kHz audio decoding. This means the signal processing is designed to minimize current noise, ensuring that the audio remains clean even when the device is drawing power. The inclusion of a 60W Power Delivery (PD) charging capability is significant here. It allows the adapter to handle fast charging requirements for modern smartphones and tablets like the Galaxy S22 series, iPad Pro, or iPhone 16 models without throttling performance. If you are a parent managing multiple devices or a gamer who refuses to let their battery drain during a session, this multi-port flexibility is a game-changer.
However, this versatility comes with a physical footprint that is larger than standard dongles. The red housing and the extra ports make it less "plug-and-play" for someone constantly shoving accessories into a tiny backpack side pocket. It is designed more for a desk setup, a bedside table, or a car mount where the cable length can be managed. It is also worth noting that data transmission is explicitly not supported by this model. If your primary goal is transferring files while listening to audio, this adapter will not work for you. But if your sole focus is entertainment—specifically for movies, music, and calls while maintaining a full battery—the caojunzhen 1 offers a level of connectivity that simple splitters simply cannot match.

The esbeecables USB C adapter takes a completely different approach, prioritizing reliability, portability, and value through quantity. Instead of trying to do everything at once, it perfects the essential task: getting clear audio while charging. The standout feature here is the packaging itself; it comes as a 2-pack. In the world of small electronic accessories, losing a dongle is a common tragedy. Having a spare ready in your bag or at the office eliminates the panic of being left without a way to listen to music on a long flight. This makes it an excellent choice for the best bluetooth headphone for movies experience when paired with a Bluetooth transmitter, or simply for anyone who relies heavily on wired connections and needs a backup.
Durability is another major selling point for this model. The connector is crafted from aluminum, which resists corrosion and physical wear far better than the plastic housings found on many competitors. The cable itself uses TPE material, which adds flexibility and prevents tangling. When you are traveling, whether it's a road trip across the country or a quick commute to the office, this adapter fits easily into a pocket without adding bulk. It is designed for the mobile user who values a sleek, compact profile. The audio performance is driven by an advanced DAC chip that supports up to 24-bit/48kHz resolution, delivering rich, lossless sound that reduces noise effectively. For those seeking the best headphones for movies on a plane or train, this stable connection ensures that dialogue remains crisp and bass lines remain tight.
While the esbeecables USB C supports up to 60W PD fast charging, matching the power delivery of the caojunzhen 1, it lacks the third port for simultaneous dual-headphone usage. It is strictly a 2-in-1 solution: one audio output and one charging input. This limitation is actually a benefit for users who find extra ports confusing or unnecessary clutter. It is a straightforward, no-nonsense tool for people who just want their phone to play music and charge without any fuss. The plug-and-play nature means no software installation is required, making it instantly usable across a vast array of devices, including the latest iPhone 17 series, Samsung Galaxy S25 models, and various iPads. If you are a frequent flyer or a daily commuter who loses things often, the combination of durability and the included second unit makes this the smarter investment.
• Best for multi-device households → caojunzhen 1, because it provides two headphone jacks simultaneously.
• Best for travelers and commuters → esbeecables USB C, due to its compact size and 2-pack convenience.
• Best for long-term durability → esbeecables USB C, featuring aluminum connectors and TPE cabling.
• Best for high-resolution audio → caojunzhen 1, offering support up to 24-bit/96kHz compared to 24-bit/48kHz.
• Best for charging speed → Tie, both support 60W PD fast charging.
• Best for simplicity → esbeecables USB C, as it removes the complexity of managing three ports.
• Best for shared movie watching → caojunzhen 1, allowing two people to listen at once.

After weighing the specifications and real-world utility of both options, I would buy the esbeecables USB C for my personal needs. While the caojunzhen 1 is impressive for its ability to split signals, the reality of modern travel is that we rarely need three ports open at once. The durability of the aluminum build and the peace of mind that comes with having a spare adapter in the 2-pack outweighs the novelty of the third port. For movies, specifically, the esbeecables USB C delivers the consistent, noise-reduced audio quality needed to enjoy films on a plane or train without interruption. I recommend the esbeecables USB C because it is built to last, easy to carry, and ensures you never miss a beat because you lost a tiny dongle.
