The Orka Two is a premium prescription hearing aid with excellent feedback handling and above-average music streaming, best suited for quiet listening environments.
Top 68% of Prescription Hearing AidHearAdvisor evaluated Orka Two across five independently measured lab metrics using the selected fit. 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 Orka Two.
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 plots measured insertion gain against established prescriptive fitting targets. Closer alignment indicates the device delivers amplification matched to the programmed hearing-loss profile.
Audio Samples
These recordings capture what reaches the eardrum of our acoustic test manikin while wearing the Orka Two. Compare them against the unaided reference to hear the device's effect on speech and environmental sound.

Test Configuration
The documentation below records the specific settings, equipment, and conditions used during our evaluation of the Orka Two. This transparency allows verification of our standardized testing methodology.
In its initial fit configuration with closed vented domes, the Orka Two achieved a normalized Initial Score of 4.0/5. Speech in quiet measured 3.2/5, while speech in noise was low at 1.0/5. Feedback handling was excellent at 5.0/5, and own-voice comfort scored a solid 3.2/5. Music streaming performed well at 3.3/5. This out-of-box setup delivers stable, comfortable sound with good streaming quality, though speech clarity in noisy environments is limited.
After professional tuning—still using closed vented domes—the Orka Two improved to a normalized Tuned Score of 4.3/5, a gain of 0.3 points. Speech in quiet rose to 3.7/5, and speech in noise increased slightly to 1.4/5, though this remains a low absolute score. Feedback handling stayed excellent at 5.0/5, while own-voice comfort and music streaming held steady at 3.2/5 and 3.3/5 respectively. Tuning provided meaningful improvement in quiet speech clarity without requiring coupling changes.
