Bose QuietComfort 45/QC45 Wireless vs Sennheiser ACCENTUM Plus

The Bose QuietComfort 45/QC45 Wireless have a few advantages over the Sennheiser ACCENTUM Plus Wireless, although it depends on your specific priorities as to which is ultimately better for your needs. The Bose are more comfortable and sound more consistent between wears. Their noise isolation is better, particularly when reducing mid and low-pitched noise, like ambient din and engine rumblings. The default sound is bright and piercing unless you use the basic EQ in-app. They also only let you listen with ANC or transparency modes on. The Sennheiser's battery life is more than twice as long-lasting. They have more connectivity options with aptX Adaptive codecs, which can allow for lower latency playback and higher resolution Bluetooth audio, plus they support USB audio. Their app offers a bit more utility with EQ and assignable touch controls. However, the Sennheisers are less portable, don't fold down, and won't filter out as much noise.
