Review on Sennheiser HD 4.50 BTNC Bluetooth Wireless Headphones Featuring Active Noise Cancellation in Black and Silver by Vinay Kumar ᠌

Sitting at home is ideal ears, but it didn’t suit me at all for the street. Returned. Got pros: Good sound quality, noise reduction is not the most ideal, weaker than Plantronics and Sony, but still works. The signal was not lost when worn, unlike plantronix, which often croaked in some urban nooks and crannies, despite the fact that the phone was a meter away in the pocket. Some cons: Ears sweat, no heat dissipation or ventilation, or moisture-absorbing fabric, like a dormouse. The earmuffs, with their soft foam rubber, are securely sucked into your ears like a plunger, sucking out your eardrums as you walk. Each step feels like a blow to the ear.
