　著名耳机制造商AKG近期面向专业用户推出一款具备抗噪功能的新型耳机AKG K28NC，该机配备一个通过单独的噪音滤波器。可使1.5 kHz以上频率的噪声降低-25 dB，1.5 kHz以下的噪音降低-15 dB。还可以有效的隔绝机械噪音，让用户得到一个更干净的听音环境。

AKG K28NC的频率响应范围为12 Hz-28 kHz，灵敏度为110 dB SPL/ mW，32Ω的阻抗。附带耳机线长 1.8 m。噪音滤波器使用1个4号电池驱动，能连续工作40小时。值得一提的是，耳机净重仅为73g，而且采用了折叠式的设计，更强调了便携性。 </p><p align="center"><br clear="all" /><img
