Sennheiser HD 450BT
Supporting aptX Low Latency and AAC codecs over Bluetooth 5.0, the HD 450BT delivers deep dynamic bass and active noise cancellation with a substantial 30-hour battery life. Its lightweight 236g build and foldable design, coupled with comfortable padding, make extended listening sessions effortless on the move. These are best for daily commuters who prioritize wireless ANC endurance over pristine studio accuracy, reflected in a low 25.3/100 studio score.
