Device requirements The RS-MS1I operating requirements are as follows: iOS16 or later Usable transceivers (As of May 2026) - ID-4100A/E + Bluetooth unit (UT-137) - ID-52A or ID-52E *1 - ID-52A PLUS or ID-52E PLUS *2 - ID-5200A or ID-5200E *3 - IC-705 *4 *1 Supported in RS-MS1I Ver.1.1.0 or later. *2 Supported in RS-MS1I Ver.1.3.0 or later. *3 Supported in RS-MS1I Ver.1.4.0 or later. *4 Supported in RS-MS1I Ver.1.2.0 or later. Preparation To use the RS-MS1I with a supported transceiver, you need an optional Bluetooth unit. See your transceiver’s instruction manual for details. Transceiver’s settings Set the following functions as shown below to use the RS-MS1I. [Function] > [CI-V] > [CI-V Transceive]: ON [Bluetooth Set] > [Data Device Set] > [Serial Port Function]: CI-V (Echo back OFF) Note: - The RS-MS1I may not work with all iPhones or iPads, even if they are one of the tested devices. This is because an application program on your device may conflict with the RS-MS1I. - The RS-MS1I may not be used, depending on the OS version, installed application, and so on. - Bluetooth LE is used for the connection with the transceiver, so there may be a time delay between the transceiver’s operation and the display on the iPhone or iPad. - When sending or receiving pictures using “FAST mode,” the headset audio will be temporarily interrupted because of the transceiver’s Bluetooth unit limitations. - You may need to connect to the Internet through a Wireless LAN, an LTE network or a 5G network for some functions. - The RS-MS1I supports only portrait orientation with the iPhone. It does not support Auto Rotate. However, landscape orientation and Auto Rotate are supported with the iPad.

Verdict

The call

The clearest difference is review sentiment: U/AWARE at 63% against RS's 16%. U/AWARE also leads on rating (3.8 vs 1.9) and update cadence (every 2 months vs every 8 months). RS's advantage is ratings volume (75 vs 12). On price, ads, in-app purchases and monetization model there is nothing between them.
