Tennmak C6 Turbo

ø8mm Dynamic Driver


The new C6 Turbo model by Tennmak proved once again that Tennmak's staff know what they're doing. These earphones have a powerful bass response and sharp highs. However, compared to Tennmak Dulcimer, these earphone's highs are just too sharp, which result in sibilance in the vocals, and even less detailed.


  • The sound quality and clarity are great. The bass is powerful and deep.
  • Extremely loud without requiring any amplification.
  • Robust build quality and an attractive design.
  • Tennmak rolled the cable in a circle inside the storage case, which is a great (and rare) choice. It ensures that you get a perfectly straight cable.


  • Noticeable sibilance in vocals and upper-mids, caused by a peak in the sibilance-area of the high frequencies.
  • No detailed retail packaging. The metal case is a storage case, not a retail packaging.

The mids are crisp and vivid, but slightly too bright. There is some noticeable sibilance in the vocals and the upper-mids.
