RESPONSE
Thank you for taking the time to review and comment on our products. Please note on the drop down boxes you can choose your cord length, connector preference and transmitters to make the handset exactly what you prefer. It defaults to modular and we usually will send modular connectors because they make changing your handset faster and easier. Saving time is also saving money.
