Audio Performance

With Sennheiser’s renowned sound engineering, audio quality is superb. The 7mm dynamic drivers deliver incredible clarity across the entire 5Hz-21kHz frequency range. The sound has tight, deep bass and crisp detailed treble. You’ll hear every detail in your music with exceptional depth.

Microphone Quality

Call quality is very good. The 4-mic beamforming array focuses on voice and eliminates background noise for clear call audio. Users sound loud and natural to callers. Wind noise reduction ensures calls sound clear even outdoors.

Noise Isolation

The closed ear tips provide excellent passive noise isolation. They block out external sounds, allowing you to focus on your music without distractions. The open ear tips let in some ambient sound so you remain aware of your surroundings.

Bluetooth 5.2 provides a stable wireless connection to your devices. Some users experienced occasional dropouts, but firmware updates seem to have addressed this. The connectivity is now solid.


The touch controls allow you to manage music, calls, volume, and voice assistants without taking out your phone. Each earbud has a touch panel that is easy to use.

Use Cases:

The Sennheiser Sport True Wireless earbuds are perfect for active lifestyles and exercise. Their sweatproof design makes them ideal for workouts like running, cycling, hiking, yoga, and hitting the gym. The customizable fit ensures they stay securely in place during any activity. With great sound and no wires to get in the way, these earbuds are a top choice for athletes and fitness enthusiasts wanting to pump up their exercise with phenomenal audio.

User Feedback Analysis:

Overall, customer reviews of the Sennheiser Sport True Wireless earbuds are very positive, with the majority of users rating them highly for their sound quality and performance during exercise.

When it comes to audio quality, the vast majority of reviewers describe the sound as exceptional, with rich, vibrant bass and crystal clear treble that brings music to life. Users mention hearing details in songs they never noticed before. According to listeners, the sound rivals over-ear headphones, which is a rare achievement for earbuds. Even picky audiophiles praise the impeccable sound.

In terms of comfort and fit, most users are able to achieve a secure, customized fit by mixing and matching the included ear tips and fins. They report the earbuds staying put remarkably well even during intense workouts and runs, with little to no slippage. However, some reviewers with smaller ears struggle to get a comfortable fit even with the smallest tips. A snug fit is crucial for both sound quality and stability during exercise.

When using the earbuds for sports and workouts, users mention the lack of wires is liberating, allowing free movement without getting tangled up. The IP54 sweatproof and splashproof rating provides peace of mind when running or at the gym. However, a common complaint is that the touch controls can sometimes be finicky when fingers are sweaty.

Battery life matches expectations for true wireless earbuds. At roughly 9 hours per charge, it’s decent but not outstanding. The extra charges from the case boost total usage time to 27 hours, which is more than enough for most users. The quick charging function is convenient for topping up before a workout.

In terms of call quality, performance is a mixed bag. Some users report clear, natural sounding calls where they and callers can hear each other perfectly. But others mention disappointing muffled call quality, especially in noisy or windy environments. The microphone performance seems hit or miss.

A handful of reviewers experienced connectivity issues like intermittent dropouts when first using the earbuds, but firmware updates seem to have largely resolved this. The connectivity is now generally reliable according to users.

Considering their stellar sound, durable and sweatproof design, and customizable fit for exercise, most users find the Sennheiser Sport True Wireless earbuds to offer excellent value and outperform similar models from other brands. Audio lovers will find these earbuds to be a superb portable listening option.
