If you're looking for earbuds with top-notch call quality for important meetings, the Audio Technica ATH-TWX7 excels, and its low latency mode provides a good experience for gaming and TV. However, consider the Sennheiser 450BT if you prefer over-ear headphones that offer excellent active noise canceling for air travel, and a longer battery life, which might be better for extended use without frequent charging. Keep in mind that ATH-TWX7 has modern features like wireless charging and is sweatproof, making them more suitable for exercise, whereas the 450BT's foldable design increases portability. Choose Audio Technica for cutting-edge features and better call performance, or Sennheiser for comfort during travel and longer listening sessions at a more affordable price. 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."

"The Sennheiser HD 450BT is a very good pair of headphones for the price, noise canceling is good and sound quality is great—quite rare at this price point. Like any product, this headset isn’t without its faults."
