headphones with different strengths. If active noise cancelling is important for your commute or frequent air travel, the Sennheiser 450BT offers excellent noise isolation, while the JBL Live 670NC's is only fair. For gaming and watching TV, the Sennheiser 450BT’s aptX Low Latency codec means less audio lag, which the JBL doesn't support. Regarding comfort, both have good ratings, but if on-ear pressure discomforts you, consider the over-ear design of the Sennheiser. The JBL, however, has a significantly longer battery life for extended use and ear/head detection features which are absent in the Sennheiser. If using in environments where calls and meetings are common, the JBL’s better call quality could be a deciding factor. Give Feedback

Sound Guys

Lily Katz | March 2022
"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."
