Could you please provide a link about such extension?
Could anybody please clarify the following confusions?
I have read a lot of reviews. We know that the HF2 is for Android phones while the HF3 is for iPhone and iPad. However, in two reviews, they mentioned that the HF2 is for iPhone and they tested the HF2 on it... I am confused.
Many places have mentioned that the HF2/3/5 are the same. Just different in the controller. However, more than one sources have mentioned that the HF5 is better than the HF2/3.
Which ones HF2/3/5 or the ER4-PT has cord that can be broken easily within a year? Is that the HF-2 or the ER4-PT or both?
I know that for the Bose QC20i, it is for iPhone/iPad but it can also be used on Android phones and laptop computers. Only the mic or volume function does not work in the Android phones. Maybe this i the same for Etymotic headphones?
Thanks.
