If portability and wireless convenience are priorities, the Audio Technica ATH-TWX7 earbuds would be better for you, especially since they feature active noise cancelling and are sweatproof, making them suited for exercise and travel. They also offer a low latency mode for better sync during gaming and videos, and support the LDAC codec for high-quality audio over Bluetooth. However, if you're looking for a more budget-friendly option and don't mind wires, the Sennheiser HD 400S headphones are a good choice, offering very good sound, comfort, and a detachable cable. They won't be as suitable for exercise or travel due to their larger size and lack of noise cancellation. Give Feedback

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 has done it again. The HD 400S performs well beyond its price range and is one of the better budget model headphones I’ve tried. It has very few bells and whistles and offers a simple means of listening that still delivers amazing clarity and quality. If you need a good first pair of headphones or need something that you can take out of the house, then the HD 400S is definitely for you."
