Open ear headphones like the Fvkzv S03 are great for situational awareness. Unlike traditional in-ear headphones, these earbuds use an open design that allows you to simultaneously listen to audio while remaining aware of your surroundings.


The Fvkzv S03 open ear headphones offer Bluetooth 5.2 connectivity, capacitive touch controls, and up to 32 hours of battery life with the included charging case. At just 2.89 ounces, these lightweight earbuds feature an over-ear clip-on design for secure fit during activities.

  • Bluetooth 5.2 provides wireless connectivity
  • Capacitive touch controls for managing music and calls
  • Up to 32 hours battery life with charging case
  • IPX4 sweat and water resistant rating


Sporting a sleek and minimalist aesthetic, the Fvkzv S03 Open Ear Wireless Headphones are available in black or white color options. The open ear design is comfortable for prolonged wear and allows you to hear ambient noises like traffic or conversations. The earbuds are not waterproof however.

Bluetooth 5.2 Technology

The Fvkzv S03 utilizes Bluetooth 5.2, offering enhancements over previous versions like improved connection stability, faster data transmission rates, and lower energy consumption. These advancements ensure a seamless and efficient wireless listening experience, highlighting the earbuds’ modern technological features.

Features and Operation

Equipped with the latest Bluetooth 5.2 chipset, the Fvkzv S03 Open Ear Wireless Headphones delivers smooth wireless connectivity and instant pairing. The capacitive touch controls onboard each earbud allow for media playback and call management. An LED display on the exterior of the charging case indicates remaining battery level.

Audio Quality

With an open ear design prioritizing awareness over isolation, the Fvkzv S03 Open Ear Wireless Headphones deliver passable but unexceptional sound performance. The open form factor results in reduced bass impact. However, the earbuds provide clear and balanced mids and highs suitable for podcasts, audio books, and casual music listening. Maximum volume levels are sufficiently loud for most environments.

Open-Ear Design and Hearing Health

The open-ear design of Fvkzv S03 not only maintains situational awareness but also minimizes the risk of ear fatigue and long-term hearing damage associated with in-ear and over-ear headphones. By not sealing off the ear canal, these headphones allow for a more natural listening experience, reducing the likelihood of increased ear pressure and potential hearing loss over time.

Microphone and Call Quality

The built-in microphones on the Fvkzv S03 Open Ear Wireless Headphones ensure clear voice pick-up during calls. While background noise isn’t significantly reduced, this is typical for open-ear designs. The call quality is adequate in quieter environments, but in noisy settings, expect more background interference. This makes the earbuds suitable for calls in less noisy areas but less ideal for loud environments.

Noise Isolation

As an open ear headphone design, the Fvkzv S03 Open Ear Wireless Headphones does not provide passive noise isolation or cancellation. Ambient noise and conversations remain audible to the user while wearing the earbuds. This enables situational awareness but reduces immersion.

Battery Life

The Fvkzv S03 earbuds offer 4-5 hours of playback on a single charge. The included charging case extends total listening time by providing an additional 32 hours, summing up to a total of up to 36-37 hours of playback. This battery performance is impressive for earbuds in this price range.

Using Bluetooth 5.2, the Fvkzv S03 Open Ear Wireless Headphones have a stable and energy-efficient wireless connection to devices like smartphones and tablets. Pairing is quick and simple. Bluetooth range is average at approximately 30 feet before audio may cut out.

The Fvkzv S03 Open Ear Wireless Headphones have capacitive touch sensors on each earbud to control music playback, calls, volume, and voice assistants. Some users report the touch controls can be overly sensitive or accidentally triggered. Physical buttons would be more difficult to activate unintentionally.

Water Resistance

With an IPX4 rating, the Fvkzv S03 Open Ear Wireless Headphones can withstand splashes of water and sweat. However, they are not fully waterproof and should not be submerged. The earbuds are suitable for workouts but not swimming.

User Feedback Analysis

With hundreds of customer reviews on Amazon, the Fvkzv S03 headphones have received largely positive feedback for their novel open ear design and value pricing. However, users note some drawbacks as well.

Comfort and Fit

Many reviewers praise the lightweight and comfortable fit of the Fvkzv S03 Open Ear Wireless Headphones. The over-ear clip design rests securely without inserting into the ear canal, enabling comfortable long-term wear. Users mention wearing them comfortably for hours when working out, commuting, walking, and at home.

Audio Quality

Customers find the open ear audio quality decent but not mind-blowing. The open design reduces bass impact compared to sealed earbuds. However, the Fvkzv S03 Open Ear Wireless Headphones provides pleasingly balanced mids and highs that excel at podcasts, audiobooks, and vocal-centric music. Just don’t expect thumping bass or noise isolation.

Situational Awareness

The standout feature for most is the ambient awareness provided by the open ear design. Users love being able to immerse in audio while remaining aware of their surroundings for safety and etiquette. This makes the Fvkzv S03 Open Ear Wireless Headphones shine for activities like exercising outdoors, commuting, or parental monitoring.

Battery Life

With up to 32 hours of total wireless playback, customers consistently praise the battery life of the Fvkzv S03 Open Ear Wireless Headphones as ahead of competitors. The low energy Bluetooth 5.2 and well optimized performance mean these buds can keep going and going.

Touch Controls

One common complaint is the finicky capacitive touch controls. Users report accidental taps and difficulty managing music and calls. Physical buttons would be an improvement for some.

Call Quality

Call quality gets mixed reviews. Voices come through clearly to recipients in quiet settings. But the open design allows substantial background noise in noisy environments. Mics pick up ambient sound instead of isolating vocals.


Nearly every reviewer agrees the Fvkzv S03 Open Ear Wireless Headphones punch well above their weight given the budget price tag. For less than $25, these wireless earbuds deliver versatility, comfort, and situational awareness that delight users.
