JBL is trying something new: an Indiegogo campaign for a set of solar-charging wireless headphones called JBL Reflect Eternal. They’re essentially a regular set of on-ear Bluetooth headphones, but the headband contains a solar energy collection panel made by Exeger, a Swedish technology company that specializes in light-powered applications.

That solar panel is the key to some pretty amazing claims from JBL regarding the Reflect Eternal’s ability to go without being plugged in. Assuming you start with a fully charged battery and only spend 3.5 hours listening to music per day, spending 1.5 hours outside per day is enough to deliver 68 hours of playtime. Two hours outside extends that to a whopping 168 hours of playtime, while 2.5 hours or more offers “virtually unlimited playtime,” according to the company’s Indiegogo page.

There is, of course, some fine print associated with these claims. They are based on the assumption that when you’re outside, you’re being exposed to at least 50,000 lux. That’s not going to be possible unless you’re outdoors during a bright, sunny day. Overcast days generally only produce about 1,000-2,000 lux. You don’t have to find your lux outside, though. Any source of light will work, including indoor lighting. JBL claims that three hours of indoor light will give you one hour of playtime.

If the light ever fails to materialize in sufficient quantities, you can still recharge the JBL Reflect Eternal via the less environmentally friendly USB-C power port. 15 minutes will get you 3 hours of playtime, and the battery can hold 24 hours of power.

Other than its solar-collection headband and charging system, the JBL Reflect Eternal bears a strong resemblance to the company’s $130 E45BT on-ear wireless headphones. Its audio and tech specs are similar, too, with 40mm drivers, JBL’s Signature Sound, access to voice assistants, and the ability to connect to multiple devices. The Reflect Eternal also offers IPX4 water-resistance and possesses a hear-through system for greater safety when in potentially dangerous situations.

Will the JBL Reflect Eternal resonate with buyers? We’re on the fence on that one. On the one hand, there are a lot of people looking for a greener choice when it comes to the products they buy, and these headphones certainly qualify. On the other hand, JBL isn’t the first company to try to crowdfund a set of solar-recharging headphones. Exod tried it in 2014 with its Helios headphones but failed to meet its campaign goal.

Since 2014, we’ve hardly seen any new attempts to make a set of solar headphones, and you’ve got to wonder why. Our guess is that the biggest benefit to the technology in most people’s minds is the elimination of charging anxiety. Because the latest wireless headphones are capable of storing between 30 and 40 hours of power, though, those concerns are far less top-of-mind for people than they used to be. We expect these numbers will only go up in the years ahead. JLab’s Epic Air Sport are a good example. With a fully-charged carrying case, they can last 70 hours.

We do need to point out that should you be interested in backing the JBL Reflect Eternals, the usual caveats around crowdfunding apply, even though JBL is obviously a well-known audio company. The campaign has already met its minimum funding requirement. It runs until January 27, with pledge amounts starting at $100 for early-bird backers. JBL claims that if the production run is successful, backers will receive their headphones as early as October 2020.

United Airlines passengers are about to get a big upgrade to their in-flight entertainment (IFE) experience over the coming years thanks to its purchase of 300,000 IFE systems from Panasonic Avionics. The new seatback systems are wildly better than what we’ve been used to, sporting large and colorful 4K OLED screens, USB-C charging ports, spatial audio support — and a feature that seems almost old-fashioned by comparison: you can connect your Bluetooth wireless headphones.

United’s upgraded Boeing 787 and Airbus A321XLR aircraft won’t be its first planes with Bluetooth, but the fact that it's a feature the airline felt was worth calling out is a stark reminder that Bluetooth -- a wireless audio technology that has been around for about 25 years -- remains a rarity on airplanes. This is despite the fact that the Federal Aviation Administration (FAA) got over its long-running fear of the tech in 2013 when it overturned its previous rules about portable device use and effectively gave airlines the green light on going blue.

JBL has formally debuted its new Tour One M2 wireless headphones and Tour Pro 2 wireless earbuds at CES 2023.

They also get better battery life and the Tour Pro 2 feature an innovative charging case with a built-in touchscreen.

CES 2023 marks the official planned availability for the Tour One M2 and Tour Pro 2 in North America: spring 2023, with pricing set at $300 for the One M2, and $250 for the Pro 2.
