Grado updates world’s only wireless open-back headphones with better sound, longer battery life

Brooklyn-based Grado has updated the world’s only wireless, open-back headphones. The on-ear $275 GW100x — the third generation of these cans — are now available via and they offer several improvements over their predecessors, like better sound and improved battery life.

Grado GW100x wireless open-back headphones.

The GW100x uses Grado’s 4th-generation 44mm driver, which the company says has a more powerful magnetic circuit, a voice coil with decreased effective mass, and a reconfigured diaphragm. The design is claimed to also improve efficiency while reducing distortion.

On the wireless side of the equation, the GW100x now use Bluetooth version 5.2, which should offer more reliable wireless connections to devices. Grado has also added Qualcomm’s aptX Adaptive Bluetooth codec (in addition to SBC and AAC), marking the first time these cans will be able to receive 24-bit wireless sound, albeit still with some compression. Previous versions only supported classic aptX, AAC, and SBC.

The GW100x have been given Bluetooth Multipoint support, which greatly improves the ease with which you can switch between two paired devices — handy for anyone who needs their phone for calls and their computer for work or other listening activities.

Battery life has also been improved. The second-generation GW100 was already impressive, with a claimed 40 hours of life, and the GW100x bumps that number up to 46 hours of listening on a two-hour charge. Charging now takes place via a USB-C port. Should the battery die, you can still use the headphones in wired mode with the included 3.5mm headphone cable.

The words “wireless” and “open-back headphones” are almost never mentioned in the same sentence because, in some ways, the two ideas are contradictory. We want wireless convenience when moving from place to place, but that’s usually accompanied by external sounds that would trash the audio quality that open-back cans are renowned for.

At the same time, the sound from these headphones tends to leak out, so it can be heard by those around you. Grado says it has significantly improved this sound leakage — by up to 60%.

Apple’s new $179 AirPods: Head-tracking spatial audio and longer battery life

After more than a year of speculation, the newest AirPods are here. Apple announced them at the company's October 18 Unleashed event, alongside the new Macbook Pro. The new version -- simply called AirPods (third-generation) -- cost $179, which places them between the entry-level AirPods (which Apple will continue to sell for $129) and Apple's $249 AirPods Pro. Preorders start today, with the new AirPods shipping the last week of October.

As speculated, the new AirPods use a design that's based on the AirPods Pro, with a shape that channels sound into your ear with better precision, but without using the silicone eartips that the AirPods Pro use -- good news for folks who have always appreciated the semi-open design of the original AirPods.

Headphone subscriptions could revive wilting battery life, with a catch

Streaming video. Streaming music. Streaming video games. So much of our digital lives are now wrapped up in monthly subscriptions; why not do the same with our devices, too?

That's the premise behind NuraNow, a headphone subscription service from Nura, the company that makes the highly customizable Nuraphone. NuraNow offers to send you a fresh set of wireless headphones or true wireless earbuds every 24 months as long as your subscription is in good standing. And while a new set of headphones every two years might seem unnecessary to some folks, a hardware subscription model like NuraNow could help address the biggest obstacle to long-term ownership of true wireless earbuds in particular: Battery life.
Living on borrowed charge
The unfortunate reality about rechargeable batteries is that their capacity drops over time. Anyone who has owned a laptop for more than a couple of years knows this first-hand. If you were able to get 10 hours' worth of life from your laptop when it was new, it probably won't be able to give you much more than six or seven hours after two years. That's because every time you recharge a lithium-ion battery, it loses a little bit of its total capacity.
