If you want a wired in-ear solution with a multi-driver hybrid architecture and premium aluminum build for critical listening, choose LEAUDIO DUNU VULKAN 2; if you need an open-back over-ear planar magnetic experience with exceptional soundstage for stationary home use, choose SENDYAUDIO Apollo Pro.
These two devices sit at opposite ends of the audio spectrum, serving completely different listeners. One is a portable, high-resolution earphone designed to be plugged directly into a source, while the other is a large, stationary headphone built for deep immersion in a controlled environment. The decision isn't about which brand is better, but rather which form factor and driver technology aligns with how you actually listen to music on your computer.
• LEAUDIO DUNU VULKAN 2: Offers a complex 8-driver hybrid design (2 dynamic + 6 balanced armature) for extreme detail and speed, housed in a milled aerospace aluminum shell; however, it requires a dedicated amplifier or DAC due to its impedance and sensitivity profile, and lacks any active noise cancellation.
• SENDYAUDIO Apollo Pro: Delivers a massive, spacious soundstage using a single 78mm planar magnetic driver with fast transient response and natural openness; however, its over-ear, open-back design offers no isolation from outside noise and limits portability significantly.
• Who is this for?: Choose the Vulkan 2 if you prioritize detailed vocal clarity and instrument separation in a compact, durable package for a computer setup or travel. Choose the Apollo Pro if you are seated at a desk and crave an immersive, wide-stage audiophile experience where realism trumps everything else.
The LEAUDIO DUNU VULKAN 2 is engineered for the listener who demands every ounce of resolution from their digital files. This is not a casual earbud; it is a precision instrument featuring a dual-dynamic plus six-balanced armature hybrid configuration per side. The inclusion of independent ultra-low frequency and low-frequency dynamic drivers, paired with custom Knowles midrange and four high-frequency balanced armature drivers, creates a layered soundscape that can resolve the finest textures in a recording. If you are someone who listens to complex orchestral pieces or intricate electronic production on your computer, the ability to separate these instruments without them bleeding into one another is a game-changer.

The physical construction of the Vulkan 2 speaks to durability and tactile quality. The shells are milled from aerospace-grade aluminum alloy, finished in a warm champagne gold tone. This isn't just aesthetic; the metal housing provides a solid feel that suggests longevity. At approximately 8 grams per side, they are incredibly light for a device packing eight drivers. The cable system is equally robust, utilizing a 4-core high-purity silver-plated single-crystal copper wire in a Litz configuration to ensure signal integrity. The Q-Lock mini modular plug system allows you to swap between a 3.5mm single-ended and a 4.4mm balanced connector, giving you flexibility depending on your computer's audio output capabilities.
However, this level of performance comes with specific requirements. The frequency response ranges from 5Hz to 40kHz, capturing a vast swath of audible and sub-audible information. With an impedance of 35 ohms and a sensitivity of 113dB/mW, these earphones will likely benefit significantly from a good external DAC or amplifier dongle when connected to a standard laptop jack. They do not have active noise cancellation, relying instead on the passive isolation provided by the fit and the included eartips. You should buy the Vulkan 2 if you want a wired, high-fidelity solution that fits in your pocket but delivers studio-grade clarity when plugged into your desktop or laptop. Skip it if you need wireless freedom or require active noise blocking for noisy environments like airplanes or busy offices.
The SENDYAUDIO Apollo Pro takes a different approach entirely, focusing on the physics of open-air acoustics through a massive 78mm planar magnetic driver. Planar magnetic technology is renowned for its fast transient response and low distortion, allowing the diaphragm to move quickly and accurately across the entire frequency range. The Apollo Pro utilizes a nano-scale composite diaphragm treated with EB evaporation deposition, creating a dense aluminum circuit layer that improves vibration control and frequency stability. This results in a sound signature that feels airy and expansive, with a soundstage that wraps around the listener in a way that closed-back headphones simply cannot replicate.
Comfort is a major selling point for this over-ear model, especially given its intended use case as a stationary desktop companion. Weighing 354g, the headset balances weight distribution effectively. The earcups feature a zebrawood enclosure and a sunburst metal mesh that adds a touch of visual elegance while maintaining structural rigidity. Inside, soft lamb leather headbands and breathable velvet ear pads create a skin-friendly seal that minimizes heat buildup during long sessions. If you spend hours mixing tracks, gaming, or deeply listening to albums at your computer, the open-back design ensures that your ears don't fatigue as quickly as they might with sealed, isolating models.
There are significant trade-offs to consider with the Apollo Pro. Because it is an open-back design, it leaks sound both in and out. You cannot use these in a shared office space without disturbing others, nor can you hear your surroundings clearly. Furthermore, the connectivity is strictly wired via a detachable triple-composite cable ending in a 4.4mm balanced connector. While the cable includes Furukawa OFC and enameled gold-plated copper strands for high fidelity, it locks you into a fixed position near your audio source. You should buy the Apollo Pro if your primary listening location is a quiet room at your computer and you value a natural, three-dimensional acoustic presentation over isolation or portability. Avoid this model if you need to wear headphones while moving around, commuting, or working in a loud environment.
• Best for detailed, high-resolution in-ear monitoring → LEAUDIO DUNU VULKAN 2, thanks to its 8-driver hybrid architecture capable of resolving micro-details down to 5Hz.
• Best for immersive, wide soundstage listening → SENDYAUDIO Apollo Pro, utilizing its 78mm planar magnetic driver to create a natural, open-back acoustic field.
• Best for portability and compact storage → LEAUDIO DUNU VULKAN 2, weighing only 8g per side and coming with a small carrying case that fits a USB DAC.

For a user specifically looking for the best IPX7 waterproof true wireless earbuds for computer setups, neither of these options fits that description as they are both wired. However, if you are choosing between these two for a computer-based high-fidelity experience, my recommendation leans heavily toward the LEAUDIO DUNU VULKAN 2. Why? Because its hybrid architecture offers a level of versatility that the Apollo Pro cannot match. While the Apollo Pro sounds magnificent in a quiet room, its open-back nature makes it useless for many real-world scenarios, such as multitasking or listening in non-soundproofed spaces. The Vulkan 2, with its compact aluminum build, comprehensive accessory kit including a carrying case for a DAC, and flexible connectivity, provides a more practical and powerful tool for daily computer use. I would buy the Vulkan 2 because it delivers studio-grade detail in a form factor that respects the constraints of modern workspaces, whereas the Apollo Pro is too specialized for a general-purpose computer audio setup.
The LEAUDIO DUNU VULKAN 2 is a wired in-ear earphone, while the SENDYAUDIO Apollo Pro is a wired over-ear headphone. Neither is a wireless earbud.
No, both products rely on passive isolation or open-air acoustics. The Vulkan 2 uses eartips for passive noise blocking, and the Apollo Pro is an open-back design that lets ambient sound in.
The SENDYAUDIO Apollo Pro is often preferred for mixing due to its open-back soundstage, which provides a more accurate representation of stereo imaging. However, the Vulkan 2 offers superior detail retrieval for critical listening tasks that require spotting minute flaws.
The Vulkan 2 comes with a 1.2m silver-plated monocrystalline copper cable with interchangeable 3.5mm and 4.4mm plugs. The Apollo Pro includes a detachable 4.4mm balanced cable made of a triple-composite mix of OFC and gold-plated copper.
