While the Sennheiser 450BT offers active noise cancelling for better sound isolation, especially useful for air travel, and a slightly longer battery life, the HD 250BT is not only more affordable but also provides a superior overall sound quality, which makes it a better choice for audio enthusiasts looking for value. Both headphones are well-built with comfort in mind and include integrated microphones suitable for calls and meetings. However, the 450BT's aptX Low Latency feature might be better for syncing audio with videos and gaming. The HD 250BT is lighter, which could be more comfortable for long listening sessions. Choose the 450BT for noise cancellation and low latency audio, or the HD 250BT for sound quality and budget-friendliness. Give Feedback

"As a lightweight, robust audio provider with a long battery life, the Sennheiser HD 250BT offer a lot for their price: very good Bluetooth codecs, an app connection and an extremely understated design. These headphones may not be among the most comfortable, but they deliver adequate sound – without overdriving or distortion."
