If you want a rugged, waterproof headset that survives submersion in water and heavy sweat for intense workouts, choose H2O Audio Surge Waterproof Sport; if you need premium wireless over-ear headphones with deep active noise cancellation and massive battery life specifically for long flights or commuting, choose CMF BY NOTHING Headphone Pro Active.
• H2O Audio Surge Waterproof Sport: Its biggest strength is total waterproof durability (IPX8) and secure fit for swimming, while its trade-off is the lack of Bluetooth connectivity and short wired-only design. This pick is for athletes who train in rain, sweat, or pools.
• CMF BY NOTHING Headphone Pro Active: Its biggest strength is advanced hybrid active noise cancellation and 50-hour battery life, while its trade-off is that it offers no water resistance and is not suitable for aquatic sports. This pick is for travelers, commuters, and audiophiles seeking isolation.
• Best for Flights: The CMF BY NOTHING Headphone Pro Active is the clear winner here due to its over-ear design, ANC, and extended battery endurance.
The H2O Audio Surge Waterproof Sport is built for one specific purpose: surviving the elements while you move. If your workout routine involves running in the pouring rain, cycling through puddles, or actually taking a lap in the pool, this is the only choice on the market that can handle it. The engineering here focuses entirely on sealing the audio drivers against moisture. With an IPX8 rating, these headphones are designed to withstand complete submersion up to 12 feet (3 meters) of water. That isn't just splash-proof marketing fluff; it means you can wear them while diving into a pool without worrying about the electronics failing.
For swimmers, the package includes five sets of high-quality earplugs ranging from XS to XL, plus three sets of tree tips. This level of customization is critical because the seal must be watertight to keep water out of the ears and the driver cavity dry. The sound profile is described as having warm, dynamic bass response, which helps drown out the muffled sounds of being underwater. The speaker shape sits flush against the ear, promoting proper alignment so the device doesn't shift during vigorous activity like surfing or paddle boarding.

However, you should skip this product immediately if you value wireless freedom or plan to use these for travel. These are wired headphones using a 3.5mm jack with a standard length cord of 3.6 feet. There is no Bluetooth capability, meaning you cannot pair them with modern smartphones for music streaming unless you have a separate MP3 player or a specific adapter setup. They rely on sound isolation rather than electronic noise cancellation to block the world around you. If you are looking for a device to sit comfortably on a plane for ten hours, the short cord and lack of ANC make this a poor choice compared to modern alternatives.
In stark contrast, the CMF BY NOTHING Headphone Pro Active is engineered for the modern commuter, the frequent flyer, and the home listener who demands high-fidelity audio without the tangle of wires. This is an over-the-ear design that utilizes memory foam earpads and a cap-friendly headband to ensure comfort during long listening sessions. The sheer scale of its battery life is impressive, offering up to 50 hours of non-stop playback with Active Noise Cancellation (ANC) turned on, and up to 100 hours when ANC is off. For anyone spending hours on a plane, train, or bus, this battery capacity eliminates the anxiety of finding an outlet or charging mid-journey.
The standout feature for travelers is the 40 dB of Adaptive Active Noise Cancellation. Unlike the passive isolation of the H2O Audio, this system actively identifies and cancels low-frequency drone, such as airplane engines or subway rumble. You can toggle instantly to Transparency Mode if you need to hear announcements or converse with someone nearby. The audio quality is further elevated by LDAC support and Dual Hi-Res Certification, utilizing custom 40mm nickel-plated drivers to deliver rich texture and energy across a frequency range of 20Hz to 96kHz. This makes it an excellent choice for "best wireless headset for flights" where clarity and silence are paramount.
Despite its strengths, this headphone is not a gym buddy. It uses faux leather and plastic materials that offer style but provide zero water resistance. You cannot wear these in the rain, let alone submerge them in water. If your primary use case involves outdoor sports, sweating heavily, or accidental splashes, the CMF headphones will likely suffer damage. They are also heavier at 283 grams compared to the lightweight nature of in-ear sport buds, which might feel cumbersome during high-intensity movement. However, for stationary activities like working, studying, or traveling, the comfort and audio immersion are unmatched.

I would buy the CMF BY NOTHING Headphone Pro Active for my personal needs, especially because I frequently travel by air. The ability to turn on active noise cancellation and disappear into a quiet zone for a 10-hour flight is something the wired, non-isolating H2O Audio simply cannot replicate. While the H2O Audio Surge is a marvel of waterproof engineering, it is too limited in functionality for general daily use. The CMF headphones strike the perfect balance between high-fidelity sound, massive battery life, and practical features like Bluetooth 5.4 and app-based EQ adjustments. For anyone prioritizing headphones for flights or general music enjoyment, the CMF BY NOTHING is the superior investment.
Yes, the CMF BY NOTHING Headphone Pro Active is ideal for flights thanks to its 40dB active noise cancellation and 50-hour battery life. The H2O Audio Surge lacks both ANC and wireless connectivity, making it less suitable for air travel.
No, the CMF headphones do not have a waterproof rating and should never be exposed to water or submersion. Only the H2O Audio Surge Waterproof Sport is designed for swimming and submersion up to 12 feet.
Since the H2O Audio Surge uses a wired 3.5mm connection, you can connect it to any device with a headphone jack or use a Bluetooth transmitter. It does not require a proprietary player, though it works well with MP3 players.
The CMF BY NOTHING Headphone Pro Active offers higher resolution audio with LDAC support and a wider frequency range (up to 96kHz), providing a more detailed and immersive listening experience compared to the standard dynamic drivers of the H2O Audio Surge.
