If you’re spending hundreds or thousands of dollars buying an OTC hearing aid, make sure you’re getting a product that offers a sustainable long-term solution to your hearing loss needs. Aside from the obvious things like sound quality, take a few minutes to look into these specs.

What size and style works best for you? Most hearing aids on the market are classified as either behind-the-ear (BTE) or in-the-ear (ITE). BTE hearing aids are probably what you think of when you picture a hearing aid, consisting of a plastic case that contains the electronics, a thin cable that goes over the ear and inside the canal, and a tiny speaker known as a “receiver,” which sends boosted audio from a person’s surroundings into their ear. By contrast, ITE models are self-contained units that look like a standard pair of wireless earbuds. In-the-ear hearing aids are popular for their incognito aesthetic, and they tend to be a lot easier to pop in and out than their behind-the-ear counterparts. Still, contemporary BTE hearing aids are significantly smaller than the ones “back in the day.” It just comes down to what fits you most comfortably.

Replaceable or rechargeable batteries? Much like wireless earbuds, most OTC hearing aids are equipped with rechargeable batteries and (usually) a portable charging case for easy transport. If you take the case’s battery life into account, you’ll find most OTC models last about a week before you need to connect to a power source. Without the case, rechargeable hearing aids offer anywhere from 10 to 24 hours of battery life per charge (but this goes down by a few hours if you’re using them to stream via Bluetooth). Replaceable batteries, such as those found on the Sony CRE-C10, can last for 70 hours or more before the battery dies. Sounds great, but it means having spares on hand and wrestling with tiny cells, which can be difficult for people with dexterity problems.

Are you comfortable making adjustments? While prescription hearing aids are fitted in-office by a licensed hearing care specialist, OTC devices are self-fitting. In most cases, OTC hearing aid users are expected to be able to tune the devices to their ears, usually with the help of a smartphone app. It’s certainly nice to make your own adjustments on the fly, but it may cost you in the way of personalized care.

What’s the company’s customer support like? If only you could count on quality support from every hearing aid manufacturer! Unfortunately, OTC hearing aid companies are just that—companies. There’s no “standard” for customer service in the industry. Companies like Jabra offer patients comprehensive support, but other brands may leave you on your own.

Is there a trial run? If you’re not happy with your hearing aids, you’ll probably want to have the option to return them without writing all that money off as a sunk cost. Most states require manufacturers to provide patients with a minimum trial period, but I recommend playing it safe by seeking out this info before buying.

What about warranties? Equally important to a reasonable trial period is the inclusion of a comprehensive manufacturer’s warranty. Most brands cover manufacturing defects for up to a year, but it goes without saying that the longer the coverage period, the better the deal. No matter which OTC hearing aid you end up with, make sure the warranty covers loss, damage, and wear and tear.

An increasingly popular solution is the inclusion of a solar panel to keep that battery topped up, enabling you to install and potentially never touch the camera again. Both Wyze and TP-Link just revealed interesting solar-powered cameras this week. Let’s talk about Wyze first.

The Wyze Solar Cam Pan ($80) is a 2K outdoor security camera that can pan 360 degrees and tilt 70 degrees. It is IP65-rated, easy to mount, and sports a small solar panel that Wyze reckons can keep the camera running on just one hour of sunlight a day (we shall see as I test through the gray depths of a Scottish winter). The Solar Cam Pan also features AI-powered person tracking, two-way audio, color night vision, a spotlight, and a siren, though you need a subscription, starting from $3 per month, to unlock smart features and get cloud video storage.

Wyze also announced a new, impressively affordable Battery Video Doorbell ($66). We started testing Wyze cameras again recently after it beefed up its security policies, but the repeated security breaches, exposing thousands of camera feeds to other customers, may still give you pause.

Meanwhile, TP-Link is the first manufacturer to combine solar power with floodlight capability in its new Tapo C615F Kit. The similar-looking but larger Tapo C615F is another 2K camera, but it pans 360 degrees, tilts 130 degrees, and, most importantly, has an adjustable 800-lumen floodlight.

TP-Link says its solar panel only needs 45 minutes of sun a day to keep the camera ticking, and it comes with a handy 13-foot cable, so you can install the solar panel in the best spot to catch those rays. The Tapo C615F ($100) is available now, and you can use the promo code 10TAPOFLDCAM to get $10 off if you’re quick. —Simon Hill

Fujifilm Updates Its X-T30 Line

Fujifilm has released the X-T30 III, an update to the company’s entry-level, SLR-shaped mirrorless X-T30 line. The third iteration of the X-T30 pairs Fujifilm’s familiar 26-MP X-Trans APS-C sensor with the latest Fujifilm processor, the X-Processor 5. The latter means that the X-T30 III is now roughly the same as the X-M5 and X-T50 in terms of internal features. All of Fujifilm’s film simulations are available, as are the subject-recognition AF modes. Video specs also see a bump up to 6.2K 30 fps open gate, and 4K 60 fps with a 1.18X crop.

The body is nearly identical to the previous model; the size, weight, and button/dial layout are the same as on the X-T30 II. The one change is that the control dial is now a film simulation dial, with three options for custom film recipes. The X-T30 III goes on sale in November at $999 for the body, or $1,150 for the body and a new 13- to 33-mm F3.5-6.3 zoom lens (20 mm- to 50 mm-equivalent). —Scott Gilbertson

Intel’s AI Experience Stores

In time for the peak shopping season, Intel is launching a variety of “AI Experience Stores” at a few key locations around the world. We don’t know exactly what they’ll be like, but Intel says these pop-ups will include an “AI-powered shopping experience” of some kind and are based on the initial launch of the trial run store in London last year.

If it keeps that same design ethos intact, these stores will be fairly immersive experiences. There will be lots of AI-driven demos on devices from the wider Windows laptop ecosystem, presumably to help drive interest and curiosity in what PCs can do. Interestingly, it comes on the back of a significant marketing push by Microsoft with its new Windows 11 AI experiences, trying to convince buyers to upgrade and explain some of the new AI features.

Here are the dates and locations below for when Intel’s stores will be open. —Luke Larsen
