If you prioritize noise cancellation for use in noisy environments, the Sennheiser 450BT is the better choice since it includes this feature unlike the HD 350BT. However, if you don't need noise cancellation and would prefer slightly longer battery life, the HD 350BT is a good option and it is also more cost-effective. Both models support AptX Low Latency for better sync during videos and gaming, and they're similar in other features like build quality and Bluetooth support. If budget is a concern and noise cancellation isn’t a necessity, the HD 350BT is a strong contender, otherwise, for more quiet and focused listening, the 450BT with its noise cancellation would be a better investment despite being slightly more expensive.
