Sennheiser HME 27
 
The new HME 27-series invites the Broadcast Commentators and Audio Engineers to experience the highest level of wearing comfort. HME 27 are a closed and circumaural earcup design to provide a high passive attenuation but nevertheless unusually lightweight and comfortable over long working hours. Soft circumaural earpads ensure a comfortable fit. The headset is similar to the HMS 26series equipped with the automatically opening two-piece headband, hence no pressure on the sensitive fontanelle. For those users who still prefer a conventional headband, a wide headband padding is included that converts the two-piece headband into a compact single piece.
Cable sold separately.
