If you want rugged, open-ear durability for outdoor activities like hunting where situational awareness is critical, choose H2O Audio TRI 2; if you need immersive sound isolation and a sleek, premium build for gaming or focused listening, choose GravaStar Sirius Plus True.
• H2O Audio TRI 2: Its biggest strength is the dual-mode bone conduction design that keeps your ears open for environmental sounds while offering underwater MP3 playback; its trade-off is that it cannot block out wind or background noise like traditional earbuds. This pick is for the hunter or athlete who prioritizes safety and hearing their surroundings over deep bass.
• GravaStar Sirius Plus True: Its biggest strength is the hybrid active noise cancellation paired with high-fidelity 10mm drivers and a stunning aluminum alloy case; its trade-off is that the in-ear design completely seals the ear canal, which blocks out the ambient noise necessary for safe hunting. This pick is for the gamer or commuter who wants total immersion and zero distractions.
The H2O Audio TRI 2 is engineered for people who refuse to disconnect from their environment, even when they are deeply engaged in audio. The core of this device is its bone conduction technology, which sits on the cheekbones rather than plugging into the ear canal. This design choice is not just about comfort; it is a safety feature. When you are outdoors, whether you are cycling down a busy street or standing still in a treeline, keeping your ears open allows you to hear approaching vehicles, wildlife, or other people. For someone looking for the best bluetooth earbuds for hunting, this open-ear architecture is non-negotiable because blocking out nature can be dangerous.
Beyond safety, the TRI 2 offers versatility that few other headsets can match. It is a dual-mode performer that switches seamlessly between land and water. On land, it streams via Bluetooth 5.3 for music and calls. But the real magic happens when you switch to MP3 mode, utilizing the built-in 8GB memory. You can store up to 2,000 songs directly on the device and take them underwater, with clear audio transmission up to 12 feet below the surface. This makes it an exceptional tool for swimmers or divers who do not want to risk damaging a standard Bluetooth unit in the pool or ocean.

However, this product is not for everyone. If you are a purist who demands silence and deep, thumping bass, the TRI 2 will feel thin by comparison. Bone conduction simply does not replicate the physical sensation of low-frequency vibrations the way sealed drivers do. Furthermore, the battery life, while solid at 8.5 hours of mixed use, is slightly lower than some competitors that prioritize long-haul streaming over aquatic performance. You should skip this product if your primary goal is to escape the world entirely through heavy noise cancellation, or if you plan to use these headphones for stationary office work where comfort might be less of a factor than pure audio fidelity.
The GravaStar Sirius Plus True is built for those who view audio as an escape and a form of high-end entertainment. The moment you hold the charging case, you notice the difference in materials. Unlike the soft silicone finishes common in sports gear, this headset features a premium aluminum alloy construction that feels cool, dense, and undeniably durable. The "War Damaged Yellow" finish gives it a distinct, street-style aesthetic that stands out. This is not just a piece of tech; it is a fashion accessory that balances trendy looks with functional robustness. If you are searching for the best gaming headset for hunting scenarios where you need to hear footsteps clearly but want to block out wind noise, the sound quality here is superior, though you must weigh the safety implications of the sealed design.
Inside the ear cups, the audio experience is driven by 10mm composite diaphragm dynamic drivers. These deliver a rich, layered soundstage with deep bass and crisp highs that make music, movies, and games feel alive. The inclusion of hybrid dual-feed Active Noise Cancellation (ANC) is the standout feature here. It actively analyzes and cancels external ambient noise, creating a bubble of silence that lets you focus entirely on your content. Combined with ENC (Environmental Noise Cancellation) for calls, this ensures that your voice comes through crystal clear even in noisy environments. Whether you are commuting on a train or trying to focus on a task, the ability to toggle between ANC and a transparent mode gives you total control over your auditory environment.
The Sirius Plus also caters to the power user who loves customization. Through a dedicated mobile app, you can adjust the EQ settings to tailor the sound to your personal preference, fine-tuning the bass or treble until it hits just right. The battery life is impressive, offering 7 hours of continuous playtime on a single charge, plus an additional 21 hours from the charging case for a total of 28 hours. With fast-charging capabilities that fully replenish the buds in just 1.5 hours, you rarely have to worry about running out of power during the day. However, the IPX4 rating means it handles sweat and light rain well, but it is not designed for submersion like the H2O Audio. If you plan to swim with these, they will not survive.

When I look at these two products, the choice really comes down to how you intend to use them in the field. For hunting specifically, I would personally buy the H2O Audio TRI 2. While the GravaStar offers better sound isolation, the inability to hear rustling leaves or approaching game makes it risky for this specific activity. The H2O Audio TRI 2 keeps my ears open so I remain aware of my surroundings while still enjoying my audio feed. That balance of safety and functionality is exactly what I need for the outdoors. If I were staying home to game or commute, I'd switch to the GravaStar for the superior noise cancellation, but for the hunt, the open-ear design wins every time.
The H2O Audio TRI 2 is often cited as one of the best options for hunting because its open-ear design allows you to hear wildlife and surroundings, whereas the GravaStar blocks out too much noise for safe hunting.
Yes, the GravaStar features hybrid dual-feed Active Noise Cancellation that effectively blocks external ambient noise, making it excellent for focusing on music or calls in loud environments.
Absolutely. The TRI 2 has a dedicated MP3 mode with 8GB of internal memory that allows for uninterrupted playback up to 12 feet underwater without needing a Bluetooth connection.
The GravaStar Sirius Plus True offers significantly longer battery life with 28 hours of total playtime (7 hours on the buds plus 21 hours from the case), compared to the 8.5-hour average life of the H2O Audio TRI 2.
