The Linner Nova Earbud delivers exceptional music streaming and feedback handling at a budget price, best for casual listeners prioritizing audio entertainment over speech clarity.
Top 58% of OTC Hearing AidThe card below displays individual measurements for speech in quiet, speech in noise, own-voice comfort, music streaming, and feedback control. 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 Linner Nova Earbud.
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.
Lab 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 Analysis
The graph below displays measured amplification across frequencies compared to established prescription targets. Insertion gain curves show how closely the device matches the acoustic output recommended for mild to moderate hearing profiles.
Processed Audio
The recordings below capture speech processed through this device using a calibrated acoustic manikin. A reference recording without hearing aid processing is included for direct comparison of sound quality differences.

Test Documentation
The lab notes below document observations from both Initial and Tuned fit conditions during testing. You will find details on the specific test configuration and any notable acoustic characteristics recorded during measurement sessions.
In initial fit testing with closed dome coupling, the Linner Nova Earbud achieves a normalized Initial Score of 3.4/5. Music streaming (4.5/5) and feedback handling (5.0/5) perform excellently. Speech in quiet (2.1/5) and speech in noise (1.3/5) both fall below category averages by 0.71 and 0.19 points respectively. Own-voice comfort is notably low at 0.5/5, trailing the category average by 2.01 points—users may experience noticeable occlusion effects when speaking.
The tuned fit configuration uses the same closed dome coupling as initial fit, resulting in an identical normalized Tuned Score of 3.4/5. All metrics remain unchanged between configurations: excellent music streaming and feedback handling persist, while speech clarity and own-voice comfort continue to trail category averages. The lack of improvement suggests the device offers limited adjustment range for optimizing speech performance beyond its out-of-box state.
