Barb Hobe –
Can these be used with a regular computer headphone jack? Do you offer a headphone with mic that does not have a removable cord?
SchoolPHONES™ –
Somehow this message was buried in our site inbox. We do NOT have a media model with a fixed cable. We made a decision to use replaceable because cables represent more than 90% on headphone failures across the industry. We wanted to offer a solution that would make field service/repair easy and economical.

E –
Do these have a regular headphone audio jack cord? The type that is round?
SchoolPHONES™ –
Making a site review today, I noted we have NOT replied to your question. Please accept my apology. SchoolPHONES cables are round 3.8mm diameter to improve strength, reduce chew damage and improve tangle resistance.
