If you want reliable sound isolation and deep bass for long flights, choose Bloody M70; if you need situational awareness and a secure fit for active travel, choose WJBCNEENT Open.
• Bloody M70: Delivers immersive audio with hybrid diaphragms and IPX4 water resistance, but relies on in-ear tips that block ambient noise completely. Best for travelers seeking total immersion and quiet.
• WJBCNEENT Open: Features an innovative clip-on design with Bluetooth 5.3 for safety and comfort during movement, though it sacrifices deep bass due to its open architecture. Best for cyclists, runners, or those who need to hear their surroundings while traveling.
• The Bloody M70 is the clear choice for passengers prioritizing noise reduction on an airplane, whereas the WJBCNEENT Open wins for anyone needing rotatable ear cups headband headphones for airplane use where they must stay alert to announcements or gate changes.
The Bloody M70 is engineered for listeners who prioritize audio fidelity and immersion above all else. At the heart of this device is the 6mm M.O.C.I. Hybrid Diaphragm Technology, which drives a dynamic driver capable of producing deep bass within a frequency range of 20Hz to 20kHz. This isn't just about volume; it is about clarity and depth. When you put these in your ears, the in-ear placement combined with the included S/M/L sleeves creates a seal that provides effective sound isolation. For someone trying to sleep on a red-eye flight or focus on a movie during a layover, this passive noise cancellation is a game-changer. You are not fighting the engine hum; you are shutting it out.
Connectivity is another area where this model shines for the average user. Utilizing Bluetooth 5.0, the M70 offers a stable transmission range up to 10 meters, ensuring that your phone stays connected even if you walk away from your seat to grab a drink. The one-step pairing process means you do not have to fiddle with menus or complex codes. Just pull them from the case, and they connect. The touch controls allow for easy media management without reaching for your device, which is crucial when you are holding a coffee or managing carry-on luggage. With a battery life of 4 hours on a single charge and a charging time of just 1.5 hours, it is ready for most short-to-medium haul flights, provided you keep the mini charging case handy for a top-up.

However, this product is not for everyone. If you suffer from sensitive ear canals or find the pressure of in-ear buds uncomfortable after an hour, the M70 will likely be a source of irritation rather than relief. The design is strictly in-ear, meaning there is no option to wear them loosely. Furthermore, while the IPX4 rating protects against sweat and light rain, it is not designed for submersion. If your primary goal is to run outdoors while listening to music, the lack of an open-air design could make you feel isolated from traffic or pedestrians. It is a dedicated audio tool, not a multi-purpose accessory.
The WJBCNEENT Open targets a completely different demographic: the active traveler and the safety-conscious commuter. Its defining feature is the "Buds-free" design. Instead of inserting anything into the ear canal, you simply clip the earphones onto your ear using high-quality memory silicone. This ergonomic approach ensures a tight grip without the discomfort of plugging the ear. For someone navigating a busy airport terminal, riding a bike through city streets, or running on a trail, this open-ear design is invaluable. It allows you to enjoy Hi-Fi professional sound quality while remaining fully aware of your environment. You can hear approaching announcements, cars, or other people, which significantly improves personal safety.
Technologically, this model pushes further with Bluetooth V5.3. This newer standard ensures smoother connections and immediate pairing, reducing the latency often found in older models. The device features Active Noise Cancellation capabilities in its control scheme, yet paradoxically maintains an open acoustic profile. This suggests the system focuses on processing voice calls or specific frequencies rather than blocking all external sound. The battery performance is robust for sports use, offering up to 5.5 hours of playback at maximum volume and a standby time of roughly 65 hours. The charging case adds significant capacity, taking only 70 minutes to saturate the buds, making it easy to keep powered up during long days of travel or workouts.
Despite these advantages, the open design comes with inherent trade-offs. Because the ear canal is not sealed, you cannot expect the deep, rumbling bass that the Bloody M70 delivers. The sensitivity is rated at 85 dB, and the frequency response starts at 5 KHz, which means you might miss some of the lower end of the audio spectrum. Additionally, the plastic enclosure and lightweight build prioritize portability over rugged durability compared to more industrial-grade gear. While the 180-day free replacement warranty offers peace of mind, the design is clearly optimized for style and function in motion rather than for creating a private, silent bubble. It is perfect for those who view headphones as an accessory or earring, adding to their look while keeping them connected.
• Best for airplane noise cancelling on ear headphones for airplane → Bloody M70. The in-ear seal and passive isolation are superior for blocking engine drone.
• Best for anc over ear headphones for airplane → Neither fits perfectly as ANC is typically active, but Bloody M70 offers better passive isolation for quiet zones.

I would buy the Bloody M70 if my primary goal was to get some rest or enjoy a movie on a plane. The ability to isolate sound with the in-ear tips and the hybrid diaphragm technology makes it the superior choice for noise cancelling on ear headphones for airplane scenarios where silence is golden. However, if I were traveling for business and needed to remain alert to gate changes, or if I planned to jog through an airport or ride a bike to my hotel, I would switch to the WJBCNEENT Open. Its rotatable ear cups headband headphones for airplane capability (via the clip-on flexibility) and open design ensure I never miss a thing. Ultimately, for pure audio immersion, the Bloody M70 wins, but for the active traveler who values safety, the WJBCNEENT Open is the smarter pick.
