The verdict
The Sennheiser HD 450BT is a very good pair of headphones for the price with great sound quality and exceptional battery life. However, the uncomfortable fit due to small ear cups and lack of advanced controls limit its appeal. While noise canceling is adequate, the Sennheiser PXC 550-II offers better overall performance for a modest price increase.
✓Liked: Excellent sound quality with balanced bass and midrange emphasis, Exceptional battery life of approximately 27-30 hours with ANC enabled, Bluetooth 5.0 with support for multiple codecs including aptX Low Latency, Portable design with removable and replaceable ear pads
✕Could be better: Uncomfortable fit with small ear cups that don't accommodate larger ears, Initial clamping force causes headband hotspot, Poor and confusing button layout requiring learning curve, No fast charging despite USB-C port
