The Sony CRE-E10 and the Lexie B2 are two well-known over-the-counter hearing aids that seniors often shortlist. One leans toward a sleek, self-contained in-ear design, the other toward a behind-the-ear style with app-guided support. This guide compares them on the practical points that decide satisfaction, without overstating what either can do for anything beyond mild-to-moderate loss.
Two OTC styles, two experiences
The Sony CRE-E10 is an in-ear, self-fitting device aimed at people who want something discreet and simple. The Lexie B2 is a behind-the-ear style built around app-based setup and adjustment. Both target adults with perceived mild-to-moderate loss, so the choice comes down to style, handling, and how much guided support the wearer wants.
Comparing what matters
Fit and handling
An in-ear design is more discreet but smaller to handle, which can challenge arthritic fingers. A behind-the-ear design is easier to grip and often easier to keep clean, at the cost of being a little more visible.
Setup and adjustment
Both rely on a smartphone app for self-fitting. Consider how comfortable the wearer is with apps, and whether one offers more hands-on help, such as remote support or a simpler guided flow.
Battery and charging
Check the charging approach and runtime for each. A rechargeable dock that covers a full day is ideal, and streaming use will shorten runtime, so factor that in if calls or TV audio matter.
| Consideration | In-ear style (CRE-E10 type) | BTE style (B2 type) |
|---|---|---|
| Discretion | More discreet | Slightly more visible |
| Handling | Smaller, trickier | Easier to grip |
| Setup | App self-fit | App self-fit + support |
| Loss range | Mild to moderate | Mild to moderate |
| Best for | Invisibility seekers | Those wanting easy handling |
Choosing between them
If the wearer prizes a device no one can see and is comfortable with a smartphone, the in-ear route is attractive. If easy handling, cleaning, and a bit more guided support are priorities, the behind-the-ear route usually wins for seniors, particularly those with reduced dexterity or vision. Both require self-fitting, so a reliable return window is essential in case the chosen style does not suit.
Before you buy
Confirm the loss is mild-to-moderate with a screening, verify your phone is supported by the app, and read the trial and warranty terms. During the trial, test the device on phone calls and in a noisy room, not just in a quiet living room, so you know how it performs where you struggle most.
Making the trial period count
Both of these over-the-counter options are self-fit, so the return window is the most important spec of all. Begin the trial by confirming the wearer can handle the chosen style comfortably, the small in-ear design rewards good dexterity and vision, while the behind-the-ear style is generally easier to grip, insert, and clean. If handling feels awkward on day one, that alone can decide the comparison regardless of sound quality.
Next, test where hearing is actually hardest. Spend time on phone calls, in front of the television, and in a genuinely noisy room, not just a quiet living room, and use the app to fine-tune the sound if the fit feels off. Note how comfortable the wearer is with app-based adjustment, since both rely on it, and whether one offers more reassuring guided support. Keep track of battery life across a full day, including any streaming, so the runtime proves adequate. By the end of the trial you will know from real experience, rather than from a spec sheet, which style suits the wearer, and you can return the other without cost.
FAQ
Which is better for someone new to hearing aids?
A first-time user who wants guidance often does better with a behind-the-ear style that offers easy handling and app-based or remote support. Confident, tech-comfortable users who want discretion may prefer the in-ear route.
Do both need a smartphone?
Both use a smartphone app for self-fitting and adjustment, so a compatible phone and some comfort with apps help a lot. Check that your specific phone model is supported before buying.
Bottom line
The in-ear and behind-the-ear OTC styles represented by the CRE-E10 and B2 both serve mild-to-moderate loss well, differing mainly in discretion, handling, and support. Pick the style that fits the wearer’s dexterity and preferences, confirm phone compatibility, and use the trial to test where hearing is hardest.
