If you value active noise cancelling and a longer battery life, the JBL Live 670NC would be the better choice, especially for air travel or noisy environments. However, if you are looking for excellent sound quality with low latency, which is great for gaming and watching TV, the Sennheiser HD 350BT would suit you better, even though it lacks noise cancelling. Both options are similarly comfortable and have very good build quality, but the Sennheisers may be preferable for extended wear due to their over-ear design. Keep in mind, the JBLs offer both wired and wireless options, giving you more flexibility if battery life or wireless connectivity becomes an issue. Give Feedback
