Operation

The headphones are fully adjustable and should be positioned for the best fit over the ears. This will give maximum long-term comfort and will minimise sound leakage or spill. Convention states that with the DT 280 / DT 290 / DT 290 V.11 / DT 291 PV / DT 294 PV / DT 294 V.11 the boom microphone is placed over the left ear. The microphone can be used from the right ear, but if true L and R headphone status needs to be maintained, it will be necessary to make a custom lead with the headphone connections reversed (swap brown/orange on the left side and red/blue on the right side). For connections refer to ”Block Diagram”.
