These are more expensive than some of the comparable designs, like the EPOS I SENNHEISER Adapt 260 and the Sony WH-1000XM3. Though, they are cheaper than the Bose 700 UC and Sony WH-1000XM4.

However, there is no active noise cancellation in the headphones, so the operator will still hear those sounds. Even without active noise cancellation, the Voyager 4320 UC provide clear sound and excellent clarity for anyone at the recipient end of the conversation.
