The HSKLock Hearing Aid is a budget-priced amplification product available for $69, earning a C grade in HearAdvisor's lab testing. As a behind-the-ear device powered by disposable batteries, it represents one of the most affordable options in the hearing amplifier market.
In our lab testing, the HSKLock demonstrated mixed performance characteristics. Its standout strength is feedback handling, scoring a perfect 5.00/5—well above the category average. This means users are unlikely to experience the whistling or squealing that can plague lower-cost devices. Own-voice comfort also measured above average, which may appeal to those sensitive to the sound of their own speech.
However, the device showed significant limitations in speech understanding, particularly in noisy environments. The speech-in-noise score of 0.10/5 fell well below the category average, indicating that users may struggle to follow conversations in restaurants, social gatherings, or other challenging listening situations. Speech in quiet performance was also below average at 2.00/5.
Notably, the HSKLock lacks Bluetooth streaming capability, so music streaming quality could not be evaluated. The device also showed no improvement between initial and tuned fit conditions, as both configurations yielded identical scores—suggesting limited adjustability. For budget-conscious consumers who primarily need amplification in quiet settings and value feedback-free operation, the HSKLock may suffice. Those who frequently encounter background noise should consider alternatives, even within this price tier.
