Why Not Just Buy the Cheap One?
Cheap ANC headphones under $80 (like Mpow or TaoTronics) have hissing noise cancellation, flimsy headbands, and muddy sound. The QC45 has world-class ANC, plush ear pads, and lasts 22 hours on a charge.
The Buy-Once Math
Two $50 cheap headsets that break in a year = $100. And they sound terrible the whole time. The QC45 lasts for years, sounds great, and retains resale value. Silence is worth the upfront cost.
