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.
NOTE: This model was most likely discontinued. It is very difficult to find for purchase.
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.
