If you want detailed, spacious wired listening for focused work from home, choose AKG 701; if you need waterproof open-ear headphones with built-in music storage for swimming and other sports, choose H2O Audio TRI 2.
These are built for very different routines. The AKG is a wired, over-ear headphone focused on accurate sound; the TRI 2 is a Bluetooth and MP3 player designed to stay useful on land and underwater. For a desk, I’d choose the AKG. For workouts in wet conditions, the H2O Audio has the clear practical advantage.
• AKG 701 strength: An open-back, over-ear design with detailed, spacious sound and a wired connection. Trade-off: It has no noise control and is not designed for swimming or outdoor awareness.
• H2O Audio TRI 2 strength: Open-ear bone conduction, IPX8 waterproofing, Bluetooth 5.3, and an 8 GB built-in MP3 player. Trade-off: Bluetooth does not work underwater, and its open-ear approach is not the same as an immersive over-ear listening experience.
• Choose AKG 701 for music, calls, and desk listening where a wired connection and sound detail matter more than portability or isolation.
• Choose H2O Audio TRI 2 for swimming and multi-sport use, especially when you want to keep your ears open to surrounding sounds.
The AKG 701 is a wired, around-ear headphone with an open-back design and a 62-ohm impedance. Its listed frequency range is 10 Hz to 39.8 kHz. The product information describes a dynamic driver, while the design emphasizes a flat-wire voice coil, a two-layer diaphragm, and a neodymium magnet system. In practical terms, that feature set points toward detailed listening, clear transients, and a roomy presentation rather than a sealed-off, noise-blocking experience.
For work from home, the AKG makes sense if your day includes music, video, or other audio at a desk and you can use a wired headphone. Its padded leather headband and shaped 3D-form ear pads are intended for comfort, and the metal arches are described as durable. The package also includes a storage cradle. The cable and 1/4-inch plug are part of the wired setup; this is not a wireless office headset with a built-in microphone listed in its features.

The H2O Audio TRI 2 is an open-ear bone-conduction headphone made for multi-sport use. It has Bluetooth 5.3 for compatible devices on land and an 8 GB MP3 player for stored music. That distinction matters: Bluetooth does not work underwater, so swimming requires MP3 or PLAYLIST+ mode. The included charging case can fully charge the headphones twice, and the headphones are listed with six to nine hours of playback depending on use and volume.
Its standout practical feature is waterproofing: the product is rated IPX8 and specified for submersion to 12 feet (3.6 meters). The design is intended for swimming, running, biking, paddling, surfing, and snowboarding. Because it is open-ear, it leaves the ear unobstructed for situational awareness. That can suit someone who wants to hear more of the surroundings while exercising, rather than shutting out the environment.
I’d choose it for sports and water, not as a direct substitute for a desk-focused over-ear headphone. Its bone-conduction speakers and open-ear fit serve a different purpose from the AKG’s around-ear design. It has no headphone jack, and the supplied details do not identify a microphone or noise-control feature. If you need a conventional headset for long work calls or detailed, immersive listening, those are meaningful limitations.
Side-by-Side: Which Should You Choose?
• Best for wired desk listening → AKG 701. Its 1/4-inch plug and over-ear design suit a stationary setup, provided your audio device supports the connection.
• Best for music without a phone nearby → H2O Audio TRI 2. The built-in 8 GB MP3 player stores music; remember that Bluetooth streaming stops being an option underwater.
• Best for sound detail and a spacious listening style → AKG 701. Its open-back construction and listed audio features are aimed at accurate, detailed listening.
• Best for staying aware of surroundings during exercise → H2O Audio TRI 2. Its open-ear bone-conduction design is built around situational awareness.
• Best for a wired setup with no battery planning → AKG 701. Its listed connection is wired, while the TRI 2 needs charging and takes about two hours to charge.
• Best for workouts that span several sports → H2O Audio TRI 2. Its stated use cases include swimming, cycling, running, paddling, surfing, and snowboarding.
• Best headset for work from home? → AKG 701 for desk audio, with a caveat. It has no listed microphone or noise control, so neither product should be treated as a complete call-focused headset based on the provided features.
The phrase “ANC gaming headphones for work from home” points to a different kind of product than either of these. Neither model lists active noise cancellation, and neither is presented with gaming-specific features. The AKG is the closer fit for desk listening, but that doesn’t make it an ANC headset.
I would choose the AKG 701 for work from home if my main need were wired, over-ear listening at a desk and I valued a detailed, spacious sound.
I would choose the H2O Audio TRI 2 only if swimming or multi-sport use were central to my routine.
In my opinion, the AKG is the more sensible pick for a home workspace; the TRI 2 wins decisively for water and outdoor activity.
Neither is a clear all-purpose call headset based on the features provided.
For desk listening, the AKG 701 is the more natural fit: it is an over-ear wired headphone built around detailed audio. The TRI 2 is designed for open-ear sports use, and neither product’s listed features include noise control or a specified microphone.
No. Bluetooth does not work underwater according to the product details. For music while submerged, use its built-in MP3 player or PLAYLIST+ mode.
The AKG 701 is not described as waterproof in its product details. For swimming or submersion, the H2O Audio TRI 2 is the relevant choice, with an IPX8 rating and specified underwater use.
The H2O Audio TRI 2 is listed with six to nine hours of playback, varying by mode and volume, and the included case can recharge it twice. The AKG 701 is wired, so its listed use does not depend on headphone battery life.
