Ertuly S03 Review


Before you make the decision to purchase the Ertuly S03 bone conduction earbuds, it’s essential to consider the following factors to ensure they meet your needs and expectations:


One of the main concerns for potential buyers is how well the earbuds fit on their head.

The Ertuly S03 earbuds feature an ergonomic design with high-quality memory silicone ear clips that securely attach to your ears without pinching.

This design ensures a comfortable and stable fit, making them suitable for various activities, including sports, workouts, and daily use.


The user experience with the Ertuly S03 earbuds is quite unique compared to traditional in-ear headphones.

The open-ear design allows users to listen to their audio content without blocking the ear canal, enabling them to stay aware of their surroundings.

This feature is particularly beneficial for those who engage in outdoor activities or require situational awareness for safety reasons.


Bone conduction technology works differently from traditional headphones, as it transmits audio vibrations through the bones of the skull rather than the ear canal.

This may result in a different sound experience compared to what you’re used to.

While the Ertuly S03 earbuds offer clear sound and powerful volume, it’s essential to understand that the audio quality may not be on par with high-end traditional headphones.

Nonetheless, many users find the sound quality satisfactory for their needs.


The Ertuly S03 earbuds come equipped with a rechargeable battery that provides several hours of continuous playback on a single charge.

It’s crucial to consider your usage habits and determine whether the battery life meets your expectations.

If you engage in long listening sessions or don’t have regular access to charging facilities, you may want to ensure the battery life is sufficient for your needs.

Battery life test of the Ertuly S03

The battery life of the Ertuly S03 earbuds is another crucial aspect to consider.

In our test, we evaluated the battery performance under different usage scenarios to provide a comprehensive analysis.

  • Casual Listening: Under casual listening conditions, with the volume at moderate levels, the earbuds can last up to 6-8 hours on a single charge. This should be more than enough for most users during daily commutes or short workout sessions.
  • Intensive Usage: During intensive usage, with the volume at maximum levels, the battery life can last up to 4-5 hours. This may be suitable for users who engage in longer workout sessions or outdoor activities.
  • Standby Time: The Ertuly S03 earbuds have an impressive standby time of up to 120 hours. This means that even when not in use, the earbuds can retain their charge for a significant amount of time, ensuring they’re always ready for your next listening session.


As previously mentioned, the Ertuly S03 earbuds are compatible with a wide range of devices that support Bluetooth 5.2.

Before purchasing, verify that your devices are compatible and can support a stable connection with the earbuds.

This will ensure a seamless pairing process and uninterrupted listening experience.

By considering these factors, you can make an informed decision about whether the Ertuly S03 open-ear wireless bone conduction earbuds are the right choice for you.

Weighing the pros and cons, along with understanding the unique features of these earbuds, will help you make the best choice for your specific needs and preferences.

First Impressions and Design

Upon unboxing the Ertuly S03 bone-conduction earbuds, we were immediately impressed with their sleek design and lightweight construction.

Sound Quality and Bone-Based Technology

When it comes to sound quality, the Ertuly S03 bone-conveyed earbuds performed well, especially considering their unique technology.

Bone conduction headphones transmit sound through vibrations in the bones of the skull, bypassing the eardrums.

As a result, the sound quality may differ from that of traditional headphones.

We noticed that the sound was clear and crisp, with a decent balance of bass and treble.

However, the bass may not be as prominent as in some traditional headphones.

There was minimal sound leakage, and the bone-induction technology allowed us to remain aware of our surroundings, an essential feature for those who prioritize safety during outdoor activities.

Additional Features: Noise Canceling Built-in Microphone

The Ertuly S03 bone-inducting earbuds come with built-in noise cancellation technology, which we found to be quite effective in reducing background noise during calls.

While it may not completely eliminate all noise, it certainly improves call quality.

The built-in microphone also worked well during our testing. Our voice was clear and audible to the person on the other end, making it a useful feature for hands-free calls.

Overall Experience and Recommendation

After thoroughly testing the Ertuly S03 bone-conduction earbuds, we believe they are a solid choice for anyone looking for an alternative to traditional headphones.

While the bass may not be as pronounced as in some other models, the overall sound quality, comfort, and unique bone-based technology make these earbuds a worthwhile investment.

We did not encounter any significant issues during our testing, but it is essential to mention that the bone-conduction technology may take some getting used to, especially for first-time users.

In summary, we would recommend the Ertuly S03 bone conduction earbuds to those who value comfort, awareness of their surroundings, and unique technology.

While they may not be perfect for bass-heavy music lovers, they still offer an enjoyable and safe listening experience.

I had high hopes for the Ertuly S03 bone conduction earbuds, but unfortunately, they fell short in a few areas.

I found myself needing to charge the earbuds more often than I would like, which can be inconvenient when I’m on the go.

That being said, there are some positive aspects to these earbuds.

The innovative design and high-quality materials make them comfortable to wear, even for extended periods.

Additionally, the Bluetooth 5.2 connectivity is reliable and provides a smooth listening experience without any interruptions.
