HSKLock Hearing Aid Expert Review
Our lab tested the HSKLock Hearing Aid using standardized measurements on an acoustic manikin. This independent review presents objective performance data for this budget behind-the-ear amplifier.

Quality data starts with quality recordings. HearAdvisor worked with GRAS to build a no-compromise front end so every test is repeatable and reliable.

Lab Assessment
HSKLock Hearing Aid Overall Verdict
Our independent evaluation weighs the HSKLock Hearing Aid across five measured performance areas. The verdict below reflects how this budget amplifier performed in our standardized lab testing protocol.
The HSKLock Hearing Aid is a budget amplifier with excellent feedback control, best for listeners prioritizing value over speech clarity.
- Excellent feedback handling5.0/5
- Very affordable at $69
- Above-average own voice naturalness for category
- Low speech clarity in quiet1.5/5
- Poor speech in noise performance1.0/5
- No music streaming capability0.0/5
Fit Conditions
HSKLock Performance Across Initial and Tuned Settings
We measured the HSKLock Hearing Aid in both its Initial out-of-box state and after Tuned adjustments. The summaries below detail how each fit condition performed against prescriptive targets.
In initial fit testing with closed dome coupling, the HSKLock achieves a normalized score of 3.0/5. Feedback handling performs excellently at 5.0/5, well above the category average. However, speech metrics are limited: speech in quiet scores 1.5/5 and speech in noise scores 1.0/5, both below category averages. Own-voice comfort is mixed at 2.8/5. Music streaming is not functional in this configuration.
What is HearAdvisor's Initial Fit?
The Initial Fit approximates the most likely settings and eartips for a typical moderate hearing loss. Results are measured across the same 72 acoustic scenes in our custom-built lab, then scored on a 5-star scale using an auditory model.
Metric Breakdown
HSKLock Hearing Aid Lab Scores
Our testing protocol measures five distinct performance areas for every amplification product. The score card below shows how the HSKLock performed on each metric in controlled laboratory conditions.
Amplification Analysis
HSKLock Insertion Gain Measurements
Insertion gain shows how much amplification the HSKLock provides at each frequency compared to unaided hearing. The graph below plots these measurements against prescriptive fitting targets.
Audio Samples
HSKLock Manikin Recordings
We captured audio through the HSKLock while fitted on our acoustic manikin in controlled test conditions. Compare these recordings below to our unaided reference to hear the amplification characteristics.
