Gjallarhorn is a fully closed-back type of headphones. Moreover, its body is made entirely of wood (from 2 parts). As with the LSA HP-02, the wood type in these headphones has been carefully selected for a long time. And it is a very important part in this model. Based on the results of many experiments, we chose 2 kinds of Wood - Curly Maple and Ash. But ash is more difficult to process. So we settled on a maple tree. Of course, we can make these headphones from, for example, Zebrano or Wenge. But they will sound very different, and perhaps no better than an old Shoe. Believe me, in this case, it is. Therefore, Gjallarhorn will only be produced from Maple and possibly Ash for the time being. If you want a darker finishing - contact us, we will make for you a dark option that you will definitely like.
