Bear with me here in this section as it is quite important if you are interested in getting a MH1. Let’s begin by explaining two standards used in making the 3.5mm TRRS plug on headset – OMTP and CTIA (both are organizations for mobile standards). For OMTP, the TRRS plug is wired as [Left-Right-Mic-Ground] (from tip-to-sleeve); for CTIA, the TRRS is wired as [Left-Right-Ground-Mic]. Since OMTP was initially endorsed by Ericsson (and Nokia, which still uses the OMTP standard), all of their cellphone, including those under the Sony Ericsson branding, uses this standard. It also got adopted by a few other cellphone manufacturers as standard before mid 2011, such as LG, Motorola, Sony and Samsung. In mid 2010, the OMTP organization transitioned itself into another organization (the WAC, if you are interest to know), and the OMTP standard for headset was subsequently being phased out by most manufacturers within the following year (* it takes time to sell off old models) in favor of the CTIA standard. Part of the big reason for adapting the CTIA standard might be due to the fact that it is the standard used by Apple on their iDevice, which represent a big share of the headset market. Standardization demands from political groups (i.e. the EU) also played a role to push for one headset standard that will work on both Android and iOS, as well as most dumbphones (except for Nokia, which doesn’t like to play with other for now).
In the event that you have acquired the wrong version for your cellphone, don’t despair – an inexpensive TRRS smart adapter will allow OTMP headset to work on a CTIA cellphone (and vice versa). This is by far one of the smallest I have found, and has pretty good build quality: Here.
