If you want a robust 24-hour battery life and ultra-low latency for gaming or synchronized video in warehouse environments, choose SOARUN 5.4; if you need a visual display to track connection status and a compact white design for quick setup, choose Nulaxy Airplane.
• SOARUN 5.4: The standout strength is its massive 24-hour RX battery life and Bluetooth 5.4 chip with aptX-LL for zero-lag audio; the trade-off is a purely analog interface with no screen or visual indicators for connection status.
• Nulaxy Airplane: Its key advantage is the built-in OLED screen that clearly shows battery levels and connected devices, plus a sleek white aesthetic; however, it offers a shorter 20-hour RX battery life and lacks the ultra-low latency aptX-LL technology found in the competitor.
• The Verdict on Fit: Choose the SOARUN 5.4 if you are running long shifts in a warehouse where battery anxiety is real and audio sync matters; pick the Nulaxy Airplane if you prioritize seeing exactly which headphones are paired before you head out the door.
The SOARUN 5.4 is engineered for users who need endurance above all else. With a 300mAh battery capacity, this adapter promises up to 24 hours of continuous playback in Receiver (RX) mode. That kind of longevity is not just a number on a spec sheet; it translates directly to real-world reliability for someone working a full shift or traveling across multiple time zones without needing to hunt for an outlet. If your workflow involves wearing these adapters for extended periods to listen to warehouse safety announcements, music, or radio feeds while moving through noisy aisles, the sheer runtime here eliminates the fear of dying mid-task.
Another critical factor for this device is the Bluetooth 5.4 chipset combined with aptX-LL technology. This specific combination targets users who cannot tolerate audio lag. In a setting like a warehouse, where timing might be crucial for syncing instructions with physical tasks, or even for personal entertainment during downtime, the low latency ensures your video and audio stay perfectly locked. The device also supports dual headphone connections, meaning you can share a single audio source with a colleague or partner without any reconfiguration. This makes it an excellent candidate for those seeking comfortable wireless earbuds for warehouse work where collaboration is frequent but wired setups are a tripping hazard.
However, this product is not for everyone. It lacks a digital display, relying instead on indicator lights for status updates. If you prefer to glance at a screen to see exactly how much battery remains or which device is currently active, the SOARUN 5.4 will feel slightly less intuitive than some modern alternatives. Furthermore, while it supports noise cancellation features via its supported media types, the focus here is on transmission stability rather than active environmental noise cancellation in the hardware itself. You should skip this model if your primary need is a visual confirmation of connection status or if you require a device that looks distinctly different from the standard black plastic aesthetic common in industrial tools.

The Nulaxy Airplane takes a different approach, prioritizing user visibility and ease of verification. The defining feature here is the integrated screen that displays both the remaining battery percentage and the list of connected Bluetooth devices. For anyone who has ever fumbled in the dark trying to figure out if their headphones actually paired before a flight or a shift change, this screen is a game-changer. It removes the guesswork entirely. You know immediately if the connection is stable and exactly how much power is left to get you through the day. This makes it particularly appealing for travelers or workers who value transparency and immediate feedback over raw battery duration.
In terms of performance, the Nulaxy utilizes a Qualcomm chipset, which is generally known for reliable connectivity. It supports both TX and RX modes, allowing you to connect two AirPods or headphones simultaneously, which is perfect for sharing audio in a shared workspace or during travel. The battery life is rated at 20 hours in RX mode and 15 hours in TX mode, powered by a 220mAh cell. While this is slightly less than the SOARUN 5.4, it is still substantial enough for most daily use cases. The device also supports charging while playing, a feature that adds flexibility if you find yourself needing a quick top-up during a break without interrupting your audio session.
This product is best suited for those who appreciate a cleaner, white aesthetic and the convenience of a visual interface. However, potential buyers should note that the call functions are limited to RX mode only; they do not work in TX mode. If you plan to make phone calls while using the device as a transmitter for a TV or airplane system, you will not be able to do so. Additionally, the lack of aptX-LL means that while the connection is stable, it may not offer the same zero-latency experience required for high-speed gaming or precise video synchronization. If your priority is having the best in-ear headphones experience with clear visual cues and a premium look, this is a strong contender, provided you don't need the absolute longest possible battery life available.
• Best for battery life → SOARUN 5.4: The 300mAh battery delivers 24 hours in RX mode, beating the Nulaxy's 20-hour claim, making it ideal for marathon work sessions.
• Best for visual feedback → Nulaxy Airplane: Only the Nulaxy includes a screen to show battery levels and connected devices, eliminating ambiguity about pairing status.
• Best for low-latency needs → SOARUN 5.4: The inclusion of aptX-LL and Bluetooth 5.4 ensures superior audio-video sync for gaming or watching content, a feature the Nulaxy does not explicitly support.
• Best for dual-device clarity → Nulaxy Airplane: The screen explicitly lists connected devices, whereas the SOARUN relies on simple LED indicators.
• Best for long-haul travel → SOARUN 5.4: With 20 hours of TX mode, it edges out the Nulaxy's 15 hours, reducing the need to recharge during long flights or road trips.
• Best for charging flexibility → Nulaxy Airplane: Explicitly supports charging while playing, ensuring you never lose audio during short breaks.
• Best for industrial durability perception → SOARUN 5.4: The black ABS enclosure and rugged design language fit better into heavy-duty environments like warehouses compared to the white finish of the Nulaxy.
• Best for call functionality → Nulaxy Airplane: Supports microphone usage in RX mode, though neither supports calls in TX mode.
After weighing the specifications and considering the unique demands of a fast-paced environment, I would personally choose the SOARUN 5.4 for my own needs, specifically when planning for a day of intense warehouse work. The 24-hour battery life is the deciding factor; knowing I won't have to worry about finding a charger in the middle of a shift provides peace of mind that the Nulaxy simply cannot match with its lower capacity. Additionally, the aptX-LL technology is a significant advantage for anyone who values crystal-clear, lag-free audio, whether for listening to instructions or enjoying content during downtime. While the Nulaxy's screen is a nice touch, the sheer reliability of the SOARUN's power and latency performance makes it the superior tool for serious, extended use.
Both devices support standard 3.5mm AUX inputs, which allows them to connect to many non-Bluetooth legacy systems, including some older safety communication gear, provided the headset has a 3.5mm jack.
The SOARUN 5.4 lasts longer, offering up to 24 hours of playback in receiver mode compared to the Nulaxy Airplane's 20 hours, thanks to its larger 300mAh battery.
No, both kits include the necessary cables; the SOARUN comes with RCA and dual airplane jacks, while the Nulaxy includes the standard 3.5mm AUX connections needed for most vehicle and aircraft systems.
For users who need to verify connections instantly without guessing, the screen on the Nulaxy Airplane adds significant convenience, even if it means sacrificing four hours of total battery runtime compared to the SOARUN.
