Gravastar’s latest wireless earbuds let you swap charging cases

Gravastar, the company known for its sci-fi-inspired audio products like the Mars Pro Bluetooth speaker, has a new set of wireless earbuds that let you swap charging cases to customize the look of your gear. The Sirius P5, which begin shipping on November 2, start at $80 but can cost as much as $100 depending on the case style you choose. There are two earbud colors (black, white) and three case styles to choose from. If you preorder them before November 1 you can get the black earbuds with all three cases, for $90.

The Sirius P5 are a set of semi-open earbuds, very similar in size and shape to the third-gen AirPods. They come with a standard USB-C charging block, which fits any of the optional cases. The P5 sit inside the block, and then the block gets inserted into your preferred case.

Each of the three cases available at launch has its own theme and materials. Gravastar calls them Defense Armor, Defense Mecha, and Defense Crystal. Some use a zinc alloy, while others use a “Lego-like” plastic. Gravastar says it will be releasing more case styles every three months.

What makes them unique (other than the swappable cases) is their embedded four-LED lighting strip that runs down the side of the charging block. These LEDs can be customized with a choice of changing colors. It’s similar to the LED light that Gravastar uses on its pricier Sirius P9 earbuds.

The earbuds get a claimed eight hours of time on a single charge and the charging block provides four full recharges, for a total of 40 hours. These numbers assume a volume level of 50%. They offer IPX4 water protection (just the earbuds), and they support Qualcomm’s aptX audio codec on non-iPhone devices. There is also a gaming mode that Gravastar says can reduce latency as low as 48 milliseconds.

These days, wireless earbuds have become a bit of a commodity, so it’s nice to see a company like Gravastar trying to find new ways to make these devices a little more interesting.

Soundcore’s clip-style earbuds are glasses- and budget-friendly

Soundcore's latest wireless earbuds are a new addition to the growing open-ear category, but this time, the company is following Bose's footsteps with a clip-style design. The Soundcore C30i have a clamshell shape that wraps around the middle of the ear, making them less likely to interfere with glasses. The C30i come in a translucent black color for $70 and are available on Amazon starting April 9. A solid white color is expected to be added later this month.

At $70, the C30i will be very attractive to anyone who liked the look of the Bose Ultra Open Earbuds, but wasn't crazy about their $299 price.

AirPods 4: Everything we know about Apple’s next wireless earbuds
Apple AirPods 3 in their case..

If the many rumors are true, Apple will announce and start selling the next version of its wildly popular AirPods in 2024. While the details remain thin, here's what we know (and what we think we know) about the fourth-generation Apple AirPods.
AirPods 4?
Let's start with the obvious: the name. Keep in mind, we're talking about the successor to the two AirPods models that Apple sells that do not have active noise cancellation—the AirPods 2 and AirPods 3, or AirPods second- and third-gen as Apple prefers to refer to them. In other words, the non-"pro" version of the AirPods.

Apple tends to be a creature of habit when it comes to product names, so there's every reason to think that the next version will follow the existing AirPods naming convention and be called AirPods fourth-generation. (Apple uses numbers and really the generation bit as a way to differentiate, but you get the idea.)

Skullcandy's new EcoBuds wireless earbuds take a novel approach to sustainability. Instead of using a rechargeable battery inside a charging case, the $40 EcoBuds come with a charging base with a short, built-in USB-C connector that's designed to draw power from the USB-C port on most smartphones, including the iPhone 15. The new earbuds are available starting March 5 at various retailers and

Skullcandy says that by eliminating the charging case battery and by building the buds from 65% certified recycled plastics, the EcoBuds achieve a 50% lower carbon footprint than comparable wireless earbuds.
