Mobile phone adapters

Mobile phone adapters connect your phone to a microphone, headphones or a USB device with a different connector from your mobile. Here you'll find adapters from Lightning and USB-C ports to a 3.5 mm jack, as well as adapters between USB-C and USB-A that let you connect a USB flash drive, MIDI keyboard or audio interface to your phone. The range includes BOYA, Avax and Revoltage. When choosing, always start with your phone's port, then check the connector on the device you want to plug in.

Which adapter do you need for an iPhone and which for Android?

Your phone's port determines the first side of the adapter. iPhones up to model 14 have a Lightning port, while the iPhone 15 and newer models, along with most Android phones, have USB-C. For Lightning, you'll find the BOYA BY-K1 and BY-K3 adapters here; for USB-C, there's the BY-K6 model with a 3.5 mm jack, plus the Avax AD602 and Revoltage USB adapters. Choose the other side according to your device: microphones and headphones usually have a 3.5 mm jack, while USB flash drives, MIDI keyboards and audio interfaces use a USB-A connection or cable.

Plug or socket: what do male and female mean?

Adapter connectors are described as male and female. Male is the plug you insert into a port; female is the socket you connect a cable to. Avax AD602 and the Revoltage adapter have a USB-C plug and a USB-A socket: you plug them into your phone, then connect a USB flash drive or MIDI keyboard cable to them. Avax AD601 is the other way round: you insert its USB-A plug into a computer or charger and connect a USB-C cable to its USB-C socket. For your phone to recognise a USB device, it must support OTG (USB On-The-Go), a feature found on most current Android phones.

Why do TRS and TRRS matter with a 3.5 mm jack?

A 3.5 mm jack can have three contacts (TRS) or four (TRRS). The socket on a phone and headphones with a microphone use TRRS: two contacts carry stereo sound, one carries the microphone signal and the last is ground. A microphone with a TRS connector therefore often won't work with a phone, even though the plug fits into the socket. BOYA BY-K3 has a TRRS socket and suits headphones with a microphone or a lavalier microphone with a TRRS connector for an iPhone with Lightning. You'll find more ways to record sound on your phone among the mobile phone microphones, and holders and other add-ons among the mobile phone accessories.
