Anyone know a Bluetooth adapter with no mic?

I’m frustrated that almost every Bluetooth adapter I’ve tried has a mic built into it. These mics are usually terrible, and in my case, the adapter is hidden away in a compartment, so no one can actually hear me.

What I want is to use my phone’s mic for calls while staying connected to my car’s speakers through the Bluetooth adapter. I think this would work if the adapter was designed for speakers only and didn’t have a mic at all.

Does anyone know of a device like this? Thanks!

You can go into your iPhone settings and disable hands-free calling (HFP) for your Bluetooth device. Just leave audio control (A2DP) enabled. That should fix your issue.

Check out the JL Audio MBTRX. It might be what you’re looking for.

Do you care about which codecs it supports? I had one years ago that didn’t have a mic, but it only worked with SBC codec. Here’s a link to it:

Can you explain what codecs are? I’m not really familiar with them.
