CSL-Computer TWS-7500 Wireless Earbuds

The CSL-Computer TWS-7500 Wireless Earbuds are a new set of open-ear bone conduction headphones that allow you to listen to music while still being aware of your surroundings. In this review, we’ll take a look at the design, sound quality, battery life, and overall performance of these unique earbuds.

Overview

The TWS-7500 earbuds have an open ear design with the drivers resting on your cheekbone to send sound waves to your inner ear. This leaves your ear canal open so you can hear ambient sounds. They connect wirelessly via Bluetooth 5.3 and feature touch controls, voice assistant access, and IPX5 water resistance.

Design and Comfort

The earbuds have an extremely lightweight and compact design at just 1.44 oz. The ear hooks are made of soft silicone that flexes to fit comfortably and securely around your ears. I found them very easy to put on and take off. The angled nozzles help direct the sound while the open ear design prevents any ear fatigue. Overall, the TWS-7500 has one of the most comfortable and stable fits I’ve tried in earbuds.

Open-Ear Design

The TWS-7500’s standout feature is its open-ear design. Unlike traditional earbuds that seal off your ear canal, these rest on your cheekbones, utilizing bone conduction technology to transmit sound vibrations directly to your inner ear. This unique design offers several advantages:

Enhanced Situational Awareness: By leaving your ears open, you can remain aware of your surroundings, making them ideal for outdoor activities like running or cycling, where safety is paramount.

Improved Comfort: The open-ear design eliminates the discomfort and pressure often associated with in-ear earbuds, making them suitable for extended wear.

Natural Sound: Bone conduction technology delivers a more natural listening experience, as it allows you to hear ambient sounds along with your music.

However, the open-ear design also has some drawbacks:

Reduced Noise Isolation: Don’t expect these earbuds to block out much external noise, as they are not designed for that purpose.

Sound Leakage: The open design can lead to sound leakage, potentially bothering those around you at higher volumes.

Sound Quality

With 10mm dynamic drivers, the TWS-7500 delivers decent sound with emphasized bass and good stereo separation. The maximum volume is sufficiently loud. However, the open ear design means sound leaks out so these won’t provide much noise isolation. The audio quality is good for podcasts and audiobooks but lacks some clarity and detail for critical music listening.

Bluetooth 5.3 Connectivity

The TWS-7500 earbuds utilize the latest Bluetooth 5.3 technology, ensuring a stable and reliable wireless connection to your devices. Bluetooth 5.3 offers several benefits over older versions:

Improved Connection Stability: Experience fewer dropouts and interruptions, even in crowded wireless environments.

Lower Power Consumption: Bluetooth 5.3 is more energy-efficient, contributing to the earbuds’ impressive 30-hour battery life.

Faster Pairing: Connect to your devices more quickly and easily with the improved pairing process.

High-Quality Audio Transmission: Bluetooth 5.3 supports high-quality audio codecs, ensuring that you enjoy the best possible sound from your earbuds.

Intuitive Touch Controls

The TWS-7500 earbuds feature intuitive touch controls on each earbud, allowing you to easily manage your music and calls without reaching for your phone. With simple taps or holds, you can:

• Play/Pause music
• Skip to the next/previous track
• Adjust the volume
• Answer/End calls
• Activate your voice assistant

The touch controls are responsive and easy to learn, making them a convenient way to control your audio experience.

Voice Assistant Compatibility

The TWS-7500 earbuds are compatible with popular voice assistants like Siri and Google Assistant. With a simple touch, you can activate your voice assistant and control your music, get directions, check the weather, or send messages, all without taking your phone out of your pocket. This feature adds another layer of convenience to your daily routine.

30-Hour Battery Life

One of the standout features of the TWS-7500 earbuds is their impressive battery life. The earbuds themselves offer up to 6 hours of continuous playback on a single charge, while the included charging case provides an additional 24 hours, bringing the total playtime to a whopping 30 hours. This means you can enjoy your music, podcasts, or audiobooks for days without needing to recharge. The LED battery indicator on the charging case lets you easily monitor the remaining power, ensuring you’re never caught off guard.

IPX5 Water and Sweat Resistance

The TWS-7500 earbuds are rated IPX5 for water and sweat resistance, making them an ideal companion for workouts and outdoor activities. This rating means they can withstand splashes, rain, and sweat without damage. So, whether you’re running in the rain or sweating it out at the gym, you can be confident that your earbuds are protected.

Conclusion

For those seeking earbuds that allow situational awareness, the CSL-Computer TWS-7500 are a budget-friendly option. The open ear design gives these a unique advantage for hearing your surroundings. While audio quality isn’t as refined as premium models, the TWS-7500 still delivers decent sound for casual listening. The comfortable and stable fit also makes them suitable for workouts and running. Overall, these versatile earbuds provide good value at an affordable price point.
