No - It is not possible for the phone to act like a headset because it requires opposite role of the profile. For Stereo audio streaming - Headsets suport the A2DP sink role and the phones are typically only A2DP source. For voice audio - Headsets support the HSP/HFP profile's Handsfree / Headset Role roles and Phones are only the HFP/HSP Profile's Audio Gateway role. iPhone is only Audio Gateway and A2DP source.

对于语音音频 - 耳机支持 HSP/HFP 配置文件的免提/耳机角色角色，而电话仅支持 HFP/HSP 配置文件的音频网关角色。
iPhone仅是音频网关和A2DP源。
