If you want waterproof in-ear headphones for running, choose H2O Audio Surge Waterproof Sport; if you need over-ear headphones for studio monitoring, choose Shure SRH440A. The clearest difference is their intended setting: the H2O Audio is built around a watertight fit and sports use, while the Shure is designed for listening, recording, and monitoring in a more controlled environment. For running, I’d choose the H2O Audio.
• H2O Audio Surge Waterproof Sport: Its in-ear design is rated IPX8 and can handle submersion up to 12 feet (3 meters); the trade-off is a wired connection, not Bluetooth.
• Shure SRH440A: Its closed-back over-ear design is made for detailed monitoring and helps reduce outside noise; the trade-off is that it is not designed for water exposure or active running.
• Choose the H2O Audio for swimming, sweat, rain, and sports where a compact in-ear fit matters.
• Choose the Shure for recording, mixing, and focused listening with an adjustable headband and cushioned earcups.
• Neither is a wireless headphone: both use a cable, but their connectors and intended uses differ.
The H2O Audio Surge Waterproof Sport is the more natural match for running and other workouts. Its in-ear speakers are designed to sit flush with the ear, and its watertight, sound-isolating fit is intended for sports use. The standout distinction is its IPX8 waterproof rating, with submersion capability listed up to 12 feet (3 meters). That makes it relevant not only for a rainy run or a sweaty gym session, but also for swimming and other water activities.
The sound is described as warm, with an emphasis on dynamic bass. Five sets of earplugs in sizes XS through XL, plus three sets of tree-tip earplugs, give you options for finding a fit. That matters with in-ear sports headphones: the seal affects both comfort and how securely the earbud sits. The 3.6-foot cord is a practical detail to consider, too. It needs to connect to a compatible audio source, and the cable is something to manage while moving.
This is a wired model with a 3.5 mm jack, not Bluetooth. The product information also lists compatible music sources such as an H2O Audio Stream Player and an Apple Watch, with Bluetooth pairing to the Apple Watch mentioned. I would check that the source you plan to use supports the connection you need before choosing it. Its design suits runners who prioritize water protection and an in-ear fit over a cable-free setup.

Who should skip it: Skip the H2O Audio if you need Bluetooth headphones that connect directly without a wire, or if you want an over-ear design for studio work.
Shure SRH440A: Who It's For
The Shure SRH440A is an over-ear, closed-back wired headphone aimed at monitoring, mixing, recording, and careful listening. Its balanced, detailed sound is intended to let listeners hear music and spoken content clearly. The closed-back design helps reduce ambient noise and keeps sound contained, which can be useful when focusing on a recording or listening in a shared room. It is a very different proposition from a waterproof sports earbud: the Shure’s strengths are its listening and work-session design, not submersion or a running-oriented fit.
Comfort and portability are part of its appeal for extended listening sessions. It has an adjustable headband and cushioned earcups, and its collapsible design makes it easier to store or carry. The detachable locking cable is another practical feature for daily studio use. The headphones connect through a 6.35 mm jack, and the package information lists a 1/4-inch threaded adapter. They are wired, so the cable and connector should fit the equipment you intend to use.
For someone choosing headband headphones for running, the Shure’s over-ear construction is a significant mismatch with the use case. Its noise-isolating design can be an advantage when you want to concentrate, but it is not the water-resistant sport option here.
Who should skip it: Skip the Shure if your priority is waterproofing, swimming, or a compact in-ear fit for runs.

Buying Considerations
Start with where you will wear the headphones. A runner who may encounter sweat or rain has a concrete reason to favor the H2O Audio: its stated waterproof protection addresses a condition the Shure’s specifications do not. If the plan includes water immersion, the H2O Audio is the only one of these two with a stated submersion capability. That is a use-case difference, not a small comfort preference.
The cable and connector deserve a check before purchase. The H2O Audio has a 3.5 mm jack and a 3.6-foot cord. The Shure uses a 6.35 mm jack, and its listed package includes a threaded adapter. Both are wired, so neither is the straightforward pick for someone who wants an entirely cable-free running setup. For the H2O Audio, confirm that your intended player supports the connection you plan to use.
Finally, match the sound and fit priorities to the task. H2O Audio describes its sound as warm with dynamic bass and uses sound isolation in its watertight fit. Shure emphasizes a balanced, detailed presentation for monitoring and critical listening, with a closed-back design that helps limit ambient noise. If you are comparing them for a run, the Shure’s studio strengths do not outweigh the H2O Audio’s sport-and-water design. If you are buying for a recording space, the H2O Audio’s waterproofing is unlikely to be the feature you need most.
For running, I would choose the H2O Audio Surge Waterproof Sport because its in-ear sports design and IPX8 protection are the better fit for sweat, rain, and water activities.
I would choose the Shure SRH440A instead for recording, mixing, or focused listening, where its closed-back fit and balanced, detailed sound are more relevant.
My deciding question is simple: do you need waterproof sports headphones, or over-ear headphones for studio work?
I would make the H2O Audio my pick for the running use case.
