Construction & Build

Both adapters models are build to last thanks to the all-metal construction and no moving parts nor fragile cable connections.

Moreover, these cable adapters inspire trust and durability by it’s weighty feel and thick metal used for the entire body of the units.

In addition to this, the adapters might have the potential to be serviced and repaired as there is a tiny star screw that connects the stereo male plug to the adapter.

Both adapters seem to be using quality internals as there is no added perceived noise, hiss nor interference to the baseline levels of any 4.4mm balanced cable that we tested.

Additionally, the signal transmitted through the adapters to the cable does not suffer from quality nor any kind of output level loss.
