If you frequently engage in calls or meetings and desire earbuds with high-quality sound for music and video, the Audio Technica ATH-TWX7 with excellent call quality, low latency mode, and active noise cancelling would be a suitable choice despite its higher price. However, if your priority is a more budget-friendly option for casual listening without the need for wireless convenience or a microphone for calls, the Sennheiser CX300S could serve you well, offering good soundstage and noise isolation, albeit with a wired connection and no active noise cancellation. Keep in mind that Audio Technica offers more modern features like app equalization and touch controls, while Sennheiser keeps it simple and may provide better durability. Give Feedback

Engadget
Billy Steele | January 2024
"There’s plenty to like about the ATH-TWX7. A robust set of features brings a lot of convenience to your day. But a few of those tools could still use some fine-tuning and the lack of automatic pausing in 2024 is a head scratcher. Still, the audio is mostly good, and transparency mode is better than most. Add in the solid call quality and the in-app voice test and the ATH-TWX7 are a worthy consideration, especially at this price. Too bad it falls short of being a more complete package some of the competition offers for a slightly larger investment."

"Sennheiser offers impressive bang for your buck when it comes to the CX 300S. Built like a tank and sounding surprisingly good for such a budget-minded earphone, the CX 300S out-classes many of its would-be competitors. Functional but beautiful, it’s the perfect in-ear listening solution for anyone who wants to hear everything and look good doing it."
