If you prefer wireless convenience for on-the-go use and need active noise cancelling for noisy environments like air travel, the Bowers and Wilkins Pi7 S2 earbuds would better suit your needs, as they offer good portability and are optimized for both Android and Apple devices. However, if you prioritize sound quality, particularly for gaming and calls, the EPOS PC38X headphones with their open-back design, superior microphone, and focus on audio fidelity will provide you with an immersive experience and are highly regarded for comfort during extended use. Keep in mind that the PC38X are wired and may not be as convenient for travel or exercise. Give Feedback

Billy Steele | March 2023
"While the overall sound quality is great, these earbuds fall short in terms of battery life, customization and ANC performance. Bowers & Wilkins’ ability to consistently deliver pristine sound isn’t enough to make up for what the Pi7 S2 lacks, which is unfortunately quite a bit."

"Lightweight and comfortable design, Mic arm with mute, Excellent tuning, Highly natural midrange voicing, Clean and separated bass, Solid soundstage dimensions. Combining all day comfort and integrated coms with a balanced and spacious sound from essentially any source, it is hard to deny the versatility and value provided by the PC38X."
