The Orka Two is a premium prescription aid with excellent feedback handling and solid music streaming, best for users prioritizing comfort and audio quality in quieter settings.
Top 63% of Prescription Hearing AidFive measured dimensions capture speech intelligibility, background noise handling, streaming fidelity, own-voice naturalness, and feedback stability. 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 prescriptive targets across the frequency range. Closer alignment between the measured curve and target indicates more accurate amplification for the fitted hearing loss profile.
Audio Samples
These recordings capture the Orka Two output through a standardized acoustic manikin under controlled conditions. Compare the processed samples against the unaided reference to hear how the device shapes incoming sound.

Test Documentation
Our technicians documented observations during both Initial and Tuned fit conditions. The notes below detail the specific test configuration and any fitting characteristics observed during measurement.
In its initial fit configuration using closed vented domes, the Orka Two achieves a normalized Initial Score of 3.9/5. Out-of-box speech clarity in quiet measures 3.2/5, with music streaming at 3.3/5 and excellent feedback control at 5.0/5. Own-voice comfort scores a solid 3.2/5. However, speech in noise performance starts low at 1.0/5. This initial setup provides reasonable everyday performance for quieter listening situations without professional adjustment.
After tuning—still with closed vented domes—the Orka Two improves to a normalized Tuned Score of 4.2/5, a gain of 0.3 points over the initial fit. Speech in quiet rises to 3.7/5, and speech in noise improves modestly to 1.4/5, though this remains below the category average. Feedback handling stays perfect at 5.0/5, while own-voice comfort and music streaming hold steady at 3.2/5 and 3.3/5 respectively. Professional fitting yields meaningful gains, particularly for speech clarity.
