Yeasound’s behind-the-ear (BTE) hearing aids currently come in two versions. This detailed review focuses on the higher-end RIC800 model, which represents the premium tier of their product lineup. This flagship model includes AI-powered noise reduction, an automatic speech-focusing system, and wireless support for Android in addition to iOS devices. In contrast, the more budget-friendly RIC700 model is compatible with Apple devices only, making the RIC800 the primary choice for users requiring cross-platform integration.
A Rapid Setup and an Accelerated Hearing Assessment
Setting up the hearing aids begins with installing the iYeasound mobile application. The software offers a simplified and highly streamlined home screen that places all the essential settings directly at the center of the user experience. Before the hearing aids are fully deployed, the in-app hearing test establishes a baseline for how sound frequencies are dynamically adjusted. This integrated diagnostic test is notable for being highly expedited compared to most other products on the market. While the test operates under the standard methodology, delivering audio pings of varying frequencies and volume levels to each ear individually, it eliminates the lengthy and unnecessary pauses that typically drag out these diagnostic procedures. Consequently, users can finish the entire hearing check in roughly five minutes instead of the ten minutes or longer usually demanded by other over-the-counter options.
Once the testing is complete, the application plots the results on a traditional audiogram chart. In practical evaluation, these diagnostic results were slightly more aggressive than what a professional, clinical audiogram would indicate, but they were close enough to be effective for an over-the-counter (OTC) product configured via an informal, in-home test. Unfortunately, if a user already has an official audiogram from an audiologist, the application does not offer any option to import the pre-existing data. Furthermore, the testing results cannot be manually edited or fine-tuned, meaning that the only way to adjust the baseline sound profile is to take the entire diagnostic test over again.
Navigating the Audio Profiles and Custom Settings
Once the initial setup is complete and the audiogram data is fully loaded, the core user experience begins. The primary dashboard of the iYeasound application displays five pre-set environmental modes: Adaptive, General, Noisy, Music, and Outdoors. The purpose of each preset is largely self-explanatory. Located directly beneath these environmental options are individual volume sliders for each ear, allowing for personalized volume levels. However, active noise cancellation options are absent from this main screen. To adjust these parameters, users must navigate into the deeper Sound Setting sub-menus, which are unique for each of the five modes with the exception of the automated Adaptive mode.
Within these Sound Setting menus, users can perform basic adjustments to low, mid, and high frequencies, though the equalizer lacks highly refined control bands. Additionally, users can select from three distinct levels of active noise reduction and adjust the directional focus of the built-in microphones. The directional settings include an omnidirectional configuration for general spatial awareness, a forward-facing mode to isolate conversations, and a highly narrow focus mode designed to isolate speech in extremely noisy environments.
Evaluating AI Features Against Manual Optimization
The Adaptive mode is where the onboard AI capabilities of the RIC800 are fully utilized. When this mode is active, the companion app disables all manual audio customization and microphone steering options, leaving the volume sliders as the only adjustable parameter. While this automated approach sounds highly convenient, real-world usage reveals that the General mode often provides a superior and more satisfying acoustic experience. Manual fine-tuning in General mode, particularly when pushing the active noise reduction features to their maximum thresholds, proved more effective than the automated algorithms. The General mode features a lower noise floor, avoiding the audible background hiss that becomes noticeable in Adaptive mode as the volume is turned up. This manual configuration also minimizes the boomy resonance often associated with closed-ear configurations. When using the included open ear tips, the auditory performance between the Adaptive and General modes becomes more of a draw. The retail packaging includes several sizes of open, closed, and hybrid ear tips to allow users to find their ideal acoustic fit.
Assessing Sound Quality, Bluetooth Streaming, and Bass Response
Looking at the overall audio performance, the hearing aids deliver an effective, though slightly imperfect, sound enhancement experience. Mid-frequency sounds can sometimes come across as somewhat muddy or muffled, and this minor lack of clarity also affects lower-frequency tones to a lesser extent. Despite these frequency limitations, the active noise cancellation system is surprisingly robust, and the devices can be pushed to exceptionally high volume levels without introducing any distracting audio distortion or clipping.
Beyond hearing assistance, the RIC800 performs admirably as a wireless headset for audio streaming and phone calls. Many behind-the-ear (BTE) hearing aids struggle with media playback, producing flat, tinny audio that ruins the music-listening experience. Yeasound has addressed this common issue by tuning the RIC800 with a surprisingly robust and punchy bass response, making music and podcasts highly enjoyable. The units also feature built-in support for Auracast, ensuring compatibility with next-generation Bluetooth broadcasting systems in public venues.
The Daily Struggle with Software Stability and Connection Drops
In terms of physical comfort, the ergonomic design of the RIC800 allows for painless, extended wear throughout the day. However, this comfort is offset by a series of software-related issues that can severely test a user's patience. The most prominent issue lies within the companion app. The software frequently loses its wireless connection to the hearing aids when the physical units are removed from the ears, and occasionally, these disconnections occur completely at random during active wear. During these connection drops, the hearing aids continue to process ambient audio, but the app loses all control over them. Resolving this issue requires the user to cycle their smartphone's Bluetooth radio off and on, force-quit the application, and launch it again. What begins as a minor inconvenience quickly turns into a frustrating daily chore, often requiring three to four manual application resets each day to maintain app-to-device communication.
Real-World Battery Performance and Contact-Free Charging
Another area of concern is the battery performance, which falls significantly short of the manufacturer's official specifications. Yeasound advertises up to 31 hours of operation on a single charge. However, rigorous testing under mixed-use conditions—combining standard hearing assistance with Bluetooth media streaming—yielded a maximum battery life of only 18 hours. While 18 hours is still sufficient to get most users through a standard day of activity, it represents a substantial deviation from the official marketing claims. On a positive note, the companion charging case, which utilizes a standard USB-C port, stores enough power to recharge the hearing aids three times over, offering ample backup power for travel.
A final, highly practical design feature is the inclusion of a contact-free charging system. Unlike traditional hearing aids that rely on exposed metal pins that align with charging docks, the RIC800 charges wirelessly using a system reminiscent of modern electric toothbrushes. This sealed design eliminates exposed metal points that are highly vulnerable to sweat-induced corrosion and rust over time, thereby extending the overall lifespan of the physical units. Yeasound also notes that the absence of external metal contacts minimizes the risk of skin irritation or contact allergies, which can sometimes occur when corroded metal touches sensitive skin behind the ear. Ultimately, the RIC800 offers a compelling yet flawed mix of high-quality audio hardware and frustrating companion software, making it a potentially challenging option for less tech-savvy users who prefer a seamless, trouble-free experience.
