As there is no accepted industry-wide standard for 4-Pole TRRS plugs & sockets, many manufacturers have developed their products with different pin layouts (eg: Nokia, Android and Apple devices). This adapter converts freely between the CTIA and OMTP standards on 4-pole TRRS accessories, allowing you to use hardware which would otherwise conflict.
The 4-Pole problem
Unfortunately when the 4pin connector was added to the 3.5mm design, a lack of standards for this implementation resulted in different brands and industry segments, wiring the pins in different ways. Basically, a 4-pole TRRS cable or adapter needs to get the Left & Right Audio, Ground + Mic signals from one device to another. However without a uniform approach, this means the wrong signal might be going to the wrong wire during transmission. With that said, the CTIA and OMTP standards are the most common, and cover 95% of all TRRS connections. This adapter will switch the wiring internally between these two standards.
TRRS is such a headache that we've dedicated an entire blog to it - read our In-Depth TRRS Explanation here - but the short story is that there are two common wiring types when dealing with 4-pole stereo headsets: The CTIA standard, arguably the most common for smartphones and gaming consoles, and OMTP, a less common standard used on older Nokia and early Android handsets. Having miss-matched equipment means your mic doesn't work!
Fortunately this simple little adapter swaps over the Sleeve and Ring terminals, effectively adapting between standards. You can go OMTP to CTIA, or CTIA to OMPT. This will get you going for voice while keeping stereo audio untouched.
The CTIA/OMTP standards issue is not exclusive to smartphones, either. With the Xbox One and PS4 both using the 3.5mm TRRS standard for their headset connections and accessories, it's easy to purchase a miss-matched headset or be forced to buy a new pair when your old faithfuls are perfectly good.
Connect one of these adapters to our TRRS Audio/Mic splitter cables for even greater compatibility with PC gaming headsets on a wider variety of devices.

Does this work for the One plus One with my Bose QC25 headphones?
"Possibly. We don't have any wiring knowledge for either the One Plus One or the QC25, but if they are not working together when other hands-free headsets operate correctly with the One Plus One, then this adapter has a good chance of solving the issue. Unfortunately we couldn't make a guarantee without testing it."

I just ordered one of these for use on the xbox one. will it work for chat? on the item name it says CTIA to OMTP but on the item description it does OMTP to CTIA as well, is this correct?
"Yes. It is bi-directional. If you have one device that is OMTP, and one device which is CTIA, this adapter will bridge the gap regardless of which one is which. OMTP to CTIA or CTIA to OMTP - it is the same TRRS terminal swap."

Hi, i was wondering, i currently have issues with my earphones used for my ps4, currently using a iPhone 6 earphones and there is only noise from the left and the mic is quite unresponsive, I'm looking to buy another earphone and i was just wondering if i use this plug will the noise be coming from both earplugs? and not make feedback as it is quite annoying to play with my friends when there is an apparent loud feedback...rnrnthank you?
"From information concerning the Dual Shock 4 available online, Apple-compatible headsets and earphones are not compatible with the PS4 (or Xbox One) due to the way Apple uses the Mic/Ground lines for call and media playback controls, and unfortunately this adapter will not solve the issue."

Hi - I have a Sennheiser Momentuem headphopnes using Android cable. When plugged in to extension 3.5 mm cannot push right in - otherwise connection faults. Will this connector fix this?? Thx?
"No. This connector would swap the mic and ground channels, effectively disabling voice features and potentially affecting audio quality. It's only good for converting OMTP/CTIA wiring pinouts.
You may have better luck with a regular TRRS extension cable (product code AVC-C5681) but it would be difficult to guarantee a good fit without seeing the problem first hand."
