The RCA Micro is a budget behind-the-ear OTC device with excellent feedback handling but limited speech clarity for most listeners.
Top 98% of OTC Hearing AidOur lab measures five performance dimensions for every hearing aid tested: speech understanding in quiet, speech in noise, streaming audio quality, feedback stability, and own-voice naturalness. Each metric below shows the RCA Micro's measured result on a 0-5 scale. The purple SoundScore graph is the overall result, and the five graphs after it break it into individual measurements for the selected fit. Each curve shows how scores are spread across all tested hearing aids, and the dot and number mark the score for RCA Micro.
Every hearing aid is lab-tested in two states — as it sounds out of the box, and after professional tuning. Switch fits to update the five metric graphs below.
How clearly speech comes through in calm, one-on-one surroundings.
Speech understanding against loud background noise — the toughest everyday test.
How natural your own voice sounds while wearing the aids, without a boomy, plugged-up quality.
Sound quality of music streamed to the hearing aids over Bluetooth.
Resistance to the whistling and squealing caused by acoustic feedback.
Our Assessment
Quality data starts with quality recordings. HearAdvisor worked with GRAS to build a no-compromise front end so every test is repeatable and reliable.
Amplification Data
The graph below plots the RCA Micro's measured insertion gain against the prescriptive target for our test audiogram. This visualization shows how closely the device matched the amplification goals across frequencies.
Audio Samples
We captured audio samples through our acoustic manikin while the RCA Micro processed speech and environmental sounds. Compare these recordings to the unaided reference to hear how the device altered the input signal.
How this hearing aid sounds in our lab scenes. Compare it out of the box and after professional tuning.

Test Configuration
Our lab notes document the specific settings, accessories, and procedures used when testing the RCA Micro. This record ensures transparency and reproducibility for our evaluation methodology.
In initial fit testing with a power dome with slits, the RCA Micro achieved a normalized score of 2.7/5. Speech performance was low across conditions, with both speech in quiet and speech in noise scoring 1.0/5. Own-voice comfort was limited at 1.6/5, and music streaming was non-functional at 0.0/5. The standout result was feedback handling at 5.0/5, indicating excellent stability out of the box with no whistling issues during our challenge protocols.
After tuning with a power dome (transitioning from the slit version), the normalized score improved marginally to 2.8/5—a gain of just 0.1 points. Speech in quiet and speech in noise remained unchanged at 1.0/5 each, and music streaming stayed at 0.0/5. The primary improvement came in own-voice comfort, which rose from 1.6/5 to 2.1/5. Feedback handling maintained its excellent 5.0/5 rating. The more occluding coupling slightly improved own-voice perception but did not address the core speech clarity limitations.
