Hi Matthew ! If you're looking for a reliable and affordable headset for cold calling, I highly recommend the Jabra Evolve 20. It offers outstanding sound quality and features a noise-canceling microphone, ensuring clear communication in both office and home settings. Another excellent option also is the Plantronics Blackwire 3220, known for its ease of use and exceptional voice clarity. The noise-canceling microphone is particularly effective at reducing background noise, making it a great choice for professional calls. Both headsets are designed to enhance cold calling experience and improve productivity :).
