This crazy Sennheiser headphones Prime Day deal is an Amazon exclusive

Sennheiser Accentum Wireless SE.

Sennheiser has just released a new version of its Accentum Wireless headphones, which it calls the Accentum Wireless SE. The two models are essentially identical save for two things: The SE has copper-colored accents, and it comes packaged with Sennheiser’s BTD 600 aptX Adaptive USB dongle. Ordinarily, the SE is priced at $200, putting it more or less between the Accentum Wireless ($180) and the Accentum Plus Wireless ($230). However, during Amazon’s Prime Day sale, the SE bundle is just $125 — a 38% discount on a set of wireless headphones that were already a great value even at their regular price.

I was deeply impressed by the Accentum Wireless when I reviewed them earlier in 2024. The combination of their design, sound quality, comfort, and price helped them stand out from the sea of wireless headphones you can buy at similar prices. The Accentum Wireless SE preserve all of these qualities (plus they add that hit of copper color) and then throw in a USB Bluetooth dongle, making them an even better value. In fact, at their Prime Day discount, they’re even less expensive than the sale price on the regular Accentum Wireless.

You should absolutely jump on this deal while you can, but here’s some more info about that dongle you should know.

The BTD 600 is a USB-A Bluetooth dongle that can give any connected device (smartphone, tablet, or PC) the ability to transmit and receive Bluetooth using one of four codecs: SBC, aptX, and aptX Adaptive. It comes with a USB-A to USB-C adapter so you can plug it directly into USB-C-equipped laptops and smartphones, including the new iPhone 15.

While some PCs possess Qualcomm’s aptX codec, I’m unaware of any that have aptX Adaptive built in, and while Macs used to have a hidden aptX software switch you could turn on, modern Macs lack any native Bluetooth codec support other than SBC and AAC.

Since the dongle comes pre-paired with the Sennheiser Accentum SE, you’ll immediately get the benefit of both aptX and aptX HD. If you end up getting a set of wireless earbuds (or another set of wireless headphones) that support aptX Adaptive, the dongle will give you additional benefits like hi-res audio up to 24-bit/96kHz and a low latency mode to improve wireless gaming.

I’d prefer if the dongle was USB-C (with USB-A adapter), that way it wouldn’t stick out from the bottom of a phone as much, but I suspect Sennheiser sees the BTD 600 as a computer-first accessory.

I love that you can plug the Accentum and Accentum SE into USB-C directly for lossless hi-res audio, but if you prefer the convenience of a wireless connection, the included dongle ensures that connection provides the highest possible audio quality.

Soundcore’s Space One Pro headphones are perfect for travel

Anker's Soundcore audio brand has a new set of wireless noise-canceling headphones that can fold up to become 50% smaller. The Space One Pro come in black and cream color options and are available starting September 5 for $200.

Soundcore calls the new folding system FlexiCurve. In addition to the usual pivots and hinges we see on normal fold-up/fold-flat designs, the Space One Pro use a five-segmented headband, where each segment maintains a folding angle of 5 to 8 degrees, letting the headphones fold into an almost circular shape.

Noble Fokus Apollo headphones are the first with planar and dynamic drivers
Noble Fokus Apollo.

Sony, Sennheiser, Bose, Bowers & Wilkins, Master & Dynamic, and Focal -- when it comes to high-end wireless headphones, these are the brands that typically attract those who care a lot about audio quality. But that might change now that Noble has released its first set of wireless, noise-canceling headphones -- the $649 Noble Fokus Apollo. They're available starting September 3.

Noble might not be a household name like those other brands, but it has been producing audiophile-grade in-ear monitors (IEMs) for over a decade, and many of them have earned high praise from that notoriously picky community. The Fokus Apollo are very much targeted toward this same type of buyer, with a novel combination of drivers plus wireless hi-res audio codecs.

Bang & Olufsen’s latest headphones look gorgeous and cost a fortune
Bang & Olufsen Beoplay H100.

Iconic Danish audio brand Bang & Olufsen (B&O) is well known for both its stunning industrial design, as well as its premium prices, but we still weren't quite prepared for its new Beoplay H100 wireless headphones. They're sleek, built from a combination of leather, aluminum, and scratch-resistant hardened glass, and each earcup has a rotating "haptic" dial for intuitive control over both volume and noise cancellation. The price for these new cans? $1,549 -- a huge increase over the company's previous flagship, the Beoplay H95, which were already pricey at $800.

If you can afford them, the B&O Beoplay H100 are available September 3 in three color options: Infinite Black, Hourglass Sand, and Sunset Apricot.
