OREI EARC-102 vs OREI EARC-201: Which One Should You Buy?
The OREI EARC-102 and EARC-201 solve opposite home-theater routing problems. The EARC-102 lets two TVs share one ARC/eARC soundbar or receiver, with a front-panel button for choosing the active TV. The EARC-201 sends one TV’s ARC/eARC audio to two soundbars, receivers or audio systems simultaneously. Both are audio-only devices that support formats including Dolby Atmos, Dolby TrueHD, DTS-HD Master Audio and DTS:X through compatible eARC equipment. There is no overall winner: choose the EARC-102 for multiple displays or the EARC-201 for multiple audio systems.

| Feature | EARC-102 | EARC-201 | What it means |
|---|---|---|---|
| Primary use case | Two TVs sharing one soundbar or AVR | One TV feeding two soundbars, AVRs or audio systems | The models solve opposite routing problems. |
| TV-side ARC/eARC connections | 2 | 1 | It is designed to accept returned audio from two displays. |
| Audio-system ARC/eARC connections | 1 | 2 | It can feed two connected audio systems simultaneously. |
| Routing behavior | Selects one TV through automatic or manual switching | Distributes one TV signal to as many as two outputs | The preferred behavior depends on whether the setup has multiple displays or multiple audio systems. |
| Manual selection | Front-panel TV selector | No manual output selector documented | Its physical button provides direct control over which television is heard. |
| Simultaneous audio outputs | 1 | 2 | Both audio-system outputs can operate at the same time. |
| Dual-device audio negotiation | Only the selected television supplies audio | Two systems receive a mutually supported audio format | The EARC-201 supports simultaneous output but may be limited by the less capable connected system. |
| Dolby Atmos and Dolby TrueHD | Supported with compatible eARC equipment | Supported with compatible eARC equipment | Both pass these formats when the complete connection chain supports eARC. |
| DTS:X and DTS-HD Master Audio | Supported with compatible eARC equipment | Supported with compatible eARC equipment | Both pass these formats when the complete connection chain supports eARC. |
| Standard ARC limitation | Cannot carry the complete set of documented lossless eARC formats | Limited to PCM 2.0 or compressed Dolby/DTS 5.1 | Both require eARC for their full high-bitrate audio capabilities. |
| CEC control | Volume and power pass-through described, but official specifications conflict | CEC volume control documented | Its CEC volume-control support is documented more consistently, although actual remote behavior still depends on connected equipment. |
| Video passthrough | No | No | Both are audio-only ARC/eARC devices. |
| Maximum power consumption | 0.45 W | 1.06 W | It has the lower documented maximum power draw. |
| Included power solution | USB cable documented; wall adapter inclusion is inconsistent | 5V/1A power adapter included | It includes a documented external power adapter. |
1x2 eARC HDMI Audio Switch
A compact audio-only switch that lets two televisions share one ARC/eARC sound system, with automatic and front-panel manual input selection.
Key technology
Buyer advantages
- Two purpose-built solutions for uncommon ARC/eARC routing configurations
- Dolby Atmos, Dolby TrueHD, DTS-HD Master Audio and DTS:X support through compatible eARC equipment
- Compact metal enclosures
- EARC-102 provides manual and automatic TV-input selection
- EARC-201 can operate two audio outputs simultaneously
Things to consider
- Neither adapter passes video
- Lossless formats require eARC support across the connected system
- CEC and remote-control behavior can vary by configuration
- EARC-201 uses a mutually supported audio format when two different systems are connected
- The two products are not interchangeable because their routing directions are opposite

1-In-2-Out eARC HDMI Audio Splitter
An audio-only splitter that sends one television’s ARC/eARC return signal to two soundbars, receivers or compatible audio systems simultaneously.
Key technology
Buyer advantages
- Feeds two ARC/eARC soundbars, receivers or audio systems from one television simultaneously
- Useful for dual-system and multi-room audio configurations
- Supports Dolby TrueHD, Dolby Atmos, DTS-HD Master Audio, DTS:X and DSD through compatible eARC equipment
- CEC is designed to preserve compatible TV-remote volume control
- Front indicators show power, TV handshake and individual output status
- Includes a 5V/1A external power adapter
- Compact metal enclosure has side ventilation
Things to consider
- Both outputs are constrained to an audio format supported by both connected systems, which can reduce format capability when the devices differ
- No documented manual selector is provided for enabling just one of the two outputs
- TV-remote volume control adjusted only one soundbar in the demonstrated setup, although an Apple TV remote controlled both
- Audio-only design cannot split or pass an HDMI video signal
- Standard ARC is limited to PCM stereo or compressed Dolby/DTS 5.1
- Practical cable limits may vary because official cable-length guidance is inconsistent

Which one should you buy?
The OREI EARC-102 is the practical choice for a room with two displays and one soundbar or receiver. Its manual selector makes it easy to move audio between televisions, which is useful for sports setups or a TV-and-projector installation. Its tradeoffs are that only one TV can be heard at a time, cables connect on more than one side of the compact enclosure, and official CEC information is inconsistent. The EARC-201 is designed for the reverse arrangement: one TV feeding two soundbars, receivers or other ARC/eARC audio systems simultaneously. It is the better fit for dual-system or multi-room audio, but the two connected systems must share a compatible audio format, and remote-volume behavior can vary. Neither adapter is a video switch or splitter, so shoppers needing video distribution should look elsewhere.
