Shokz OpenSwim Pro Open-Ear MP3 Review: Pool and Land Audio

Who Should Buy It

Key Specifications

Overview

The Shokz OpenSwim Pro Open-Ear MP3 is positioned as an open-ear sport headphone for swimming, water sports, and land-based workouts. The product listing highlights IP68 waterproofing, 32GB of internal MP3 storage, Bluetooth for land use only, and up to nine hours of battery life. A 10-minute quick charge is said to provide three hours of listening time. The design is described as slim, lightweight, and secure enough to work with swim caps, goggles, sunglasses, and bike helmets.

The listing does not publish several important details, including driver type, weight, included accessories, and Bluetooth codec support. This review therefore relies on the published specifications and general knowledge of open-ear headphone design, not in-person testing. Buyers should treat audio performance as partly unspecified, especially in terms of bass response and overall sound signature. The stated budget tier suggests an accessible price, but the listing focuses on feature set rather than technical audio specs.

Sound Quality

The OpenSwim Pro uses an open-ear design, which typically leaves the ear canal open and allows ambient sound to reach the listener. This approach supports safety and situational awareness, but it often reduces bass extension and passive isolation compared to in-ear or over-ear models. The listing describes premium audio and vivid underwater sound, but it does not publish driver type, frequency response, or impedance, so objective sound quality remains unverified.

In MP3 mode, the headphones play stored files offline, which is useful for swimming where Bluetooth is not available. The listing says the player can store up to 8,000 songs, giving a large local library. Underwater sound can be affected by fit and water pressure, but the listing does not describe any specific equalization or underwater tuning. Buyers who prioritize audiophile detail should note that open-ear sport headphones are generally designed for clarity and awareness rather than deep bass or noise isolation.

Comfort and Fit

The product listing emphasizes a slim, lightweight, and ergonomic fit that stays in place through any workout. It specifically mentions integration with swim caps and goggles, as well as sunglasses and bike helmets. This suggests a low-profile design that sits outside the ear without adding pressure inside the ear canal. However, the listing does not state the actual weight, which is a notable omission for a product marketed for long training sessions.

Open-ear headphones typically distribute weight around the back of the head or over the ears, avoiding the fatigue some users feel with in-ear tips. The IP68 rating also implies a sealed construction that should resist sweat and water without compromising fit. Buyers who wear glasses or goggles may appreciate the stated compatibility, but individual fit can vary. Without in-person testing, the published comfort claims appear reasonable for a sport headphone, though the missing weight makes direct comparisons difficult.

Noise Control and Features

The listing does not mention active noise cancelling, and the open-ear design is not intended to block ambient sound. Instead, the headphones are built to keep you aware of your surroundings, which is a safety benefit for outdoor runners and cyclists. For swimmers, this means you will hear pool noise and your own movement, which can be useful for pace awareness. Noise isolation is not a selling point here, and buyers seeking silence should consider closed-back or in-ear ANC models.

Feature highlights from the listing include a dual-mode system, IP68 waterproofing, and 32GB of internal storage. The Shokz App allows mode toggling and audio customization, while a physical button offers quick control. Magnetic induction charging is mentioned, but the listing does not confirm whether a charging cable is included. Overall, the feature set is specialized for aquatic and outdoor exercise rather than general multimedia use.

• IP68 waterproof and submersible up to 2 meters for 2 hours
• 32GB internal storage for up to 8,000 MP3 songs
• Bluetooth for land use only, MP3 mode for swimming
• Shokz App and physical button for controls
• Magnetic induction charging mentioned
• Secure fit with swim caps, goggles, sunglasses, bike helmets

Battery, Bluetooth and Connectivity

The published battery specification is up to nine hours of continuous playback. A 10-minute quick charge is said to add up to three hours of listening time. The listing does not break down battery life by mode, so it is unclear whether MP3 playback and Bluetooth streaming consume power equally. For swimmers, nine hours should cover multiple sessions, and the fast charge is convenient when time is short.

Bluetooth is limited to land use only, which the listing states clearly. Underwater, the signal does not travel well, so the headphones automatically or manually switch to MP3 mode. The listing mentions universal compatibility with Android, iOS, Windows, and other Bluetooth devices, but it does not publish codec support such as SBC, AAC, or aptX. Call quality is described as excellent, but no microphone specifications are given.

Build, Design and Portability

The OpenSwim Pro features a triple-sealed design that achieves an IP68 rating, meaning it is fully sweatproof and can be submerged in up to two meters of water for two hours. This durability is a core selling point for swimmers and water sports. The listing describes a rugged, sweat-resistant build intended for intense workouts. However, it does not state the materials used, the overall dimensions, or the weight, so portability is only implied by the open-ear form factor.

Included accessories are not published in the listing. The mention of magnetic induction suggests a magnetic charging cable, but buyers should confirm what is in the box before purchase. Without a carrying case or extra ear hooks mentioned, the package may be minimal. The open-ear design should be easy to pack, but the lack of published weight makes it hard to assess how light the headphones feel during long sessions.

Call Quality and Daily Use

The listing states that the OpenSwim Pro ensures excellent call quality for clear conversations, but it does not provide microphone specifications or mention noise reduction for voice. Calls are only possible via Bluetooth on land, as Bluetooth does not work underwater. For daily use, the open-ear design allows you to hear traffic and surroundings, which is safer for outdoor phone calls. However, in noisy environments, call clarity may suffer without active noise cancelling or a boom microphone.

Daily use scenarios include running, cycling, gym workouts, and swimming. The IP68 rating means you do not need to worry about rain or heavy sweat. The 32GB MP3 storage lets you leave your phone behind during workouts, which many athletes prefer. The lack of active noise cancelling or a wired option may limit use in offices or airplanes, but the product is clearly targeted at active users rather than commuters.

Who Should Buy It

Swimmers and triathletes are the primary audience for the OpenSwim Pro. The combination of IP68 waterproofing, 32GB MP3 storage, and a secure fit with swim caps and goggles addresses the specific needs of pool and open water training. Runners and cyclists who value ambient awareness will also appreciate the open-ear design for safety on roads. The Bluetooth mode adds flexibility for land-based listening without a phone.

This is not the right choice for buyers who want active noise cancelling, deep bass, or in-ear isolation. Those who need to stream music while underwater will be disappointed because Bluetooth does not work submerged. If you prefer a traditional in-ear fit or need a wired option, the listing does not offer those features. The budget tier positioning suggests good value for a specialized tool, but it is not a general-purpose headphone.

Alternatives Worth Considering

For swimmers and athletes, other open-ear bone conduction models with MP3 storage exist from various brands, but the listing does not compare them directly. If you need active noise cancelling and can forgo waterproofing, over-ear models like the Sony WH-1000XM5 or Bose QuietComfort 45 offer strong isolation for travel and office use. They are not submersible and lack internal MP3 storage, so they cannot replace the OpenSwim Pro in the pool.

In-ear true wireless options such as the Apple AirPods Pro provide water resistance and portability, but they use a sealed in-ear design and do not include 32GB of storage. Wired studio headphones like the Sennheiser HD 560S and Audio-Technica ATH-M50x deliver detailed sound for home listening, but they are not built for exercise or water. The Anker Soundcore Space One offers budget ANC but is not designed for swimming. Each alternative serves a different use case, so the OpenSwim Pro remains unique for aquatic MP3 playback with open ears.

Verdict

The Shokz OpenSwim Pro is a purpose-built open-ear headphone for swimmers and outdoor athletes who want phone-free music in the water and Bluetooth streaming on land. The published specifications are compelling: IP68 waterproofing, 32GB of storage for up to 8,000 songs, nine hours of battery, and a quick charge feature. The open-ear design prioritizes safety and comfort, and the listing explicitly mentions compatibility with swim caps and goggles.

The main limitations are the lack of published driver details, weight, included accessories, and codec support, which leaves sound quality partly unknown. Bluetooth does not work underwater, so users must rely on MP3 mode for swimming. For buyers who need active noise cancelling or in-ear isolation, this is not the right product. However, within the budget tier and sport headphone niche, the OpenSwim Pro appears to offer strong value for swimmers and multisport athletes.
