Sennheiser updates its Momentum headphones with personal tuning, hi-res audio

Sennheiser has released an update to its Smart Control software — the companion app that Sennheiser customers use to adjust the settings and upgrade the firmware on the company’s wireless headphones and earbuds. The update contains a number of new features for the Momentum 4 Wireless headphones and the Momentum True Wireless 3 earbuds, including sound personalization, deeper EQ settings, a fit test, and hi-res audio at up to 24-bit/96kHz.

Both the Momentum 4 Wireless and Momentum True Wireless 3 benefit from the new Sound Personalization tuning feature, which has been designed in conjunction with the Fraunhofer Institute for Digital Media Technology (IDMT). Not sure why that matters? It’s the entity that invented the MP3 file format and it has also done tons of research in the intervening years on how people hear audio.

“The unique feature of Sound Personalization is that it can account for differences in personal sound preferences that naturally occur due to different listening levels,” said Dr. Jan Rennies-Hochmuth, head of the group Personalized Hearing Systems at IDMT in an emailed press release. “For example, some listeners prefer more treble at low levels and more bass at high levels. Sound Personalization easily detects these differences and then adjusts the playback automatically. This ensures that the sound is optimally matched no matter what the listening volume is.”

Adding to the personalization capabilities of the Momentum True Wireless 3 is an expanded equalizer. Instead of just three bands, there are now five that can be adjusted. Owners of the earbuds can also take advantage of the new fit test inside the Smart Control app, which will detect if the wearer has achieved a good seal and make recommendations on ear tip sizes if the test fails.

Finally, Momentum 4 Wireless owners will be able to unlock the full capability of their headphones. Until now, the wireless cans were firmware limited to a hi-res sample rate of 24-bit/48kHz when using the aptX Adaptive Bluetooth codec. The new firmware increases the sample rate to 96kHz, which is the highest rate supported by aptX Adaptive.

The update to the Smart Control app (4.3) for iOS and Android also contains improvements for faster device connections, faster firmware updates, and better app stability. Once you’ve updated the app and reconnected it to your headphones or earbuds, you should be prompted to begin the firmware update: 2.12.33 for Momentum True Wireless 3, and up, version 2.13.18 for Momentum 4 Wireless.

What is hi-res audio, and how can you experience it right now?
Dlyan Wireless Headphones

High-resolution audio, hi-res audio, or even HD audio -- whatever you decide to call it (for the record, the industry prefers "hi-res audio"), it's a catch-all term that describes digital audio that goes above and beyond the level of sound quality you can expect from a garden-variety MP3 file and even CDs. It was once strictly the domain of audiophiles, but now that major streaming music services like Apple Music, Amazon Music, Tidal, Deezer, and Qobuz have embraced it, almost everyone can take advantage of what hi-res has to offer.

But what exactly is hi-res audio? What equipment do you need to listen to it? Where can you download or stream it? And does it actually sound better? We've got the answers.
What does the term 'hi-res audio' mean?

The first wireless hi-res headphones with UWB will arrive in 2024
PSB M4U8 wireless headphones.

Wireless headphones (and wireless earbuds) have been hugely popular because of their wire-free convenience and handy features like active noise cancellation (ANC), but audiophiles have never been big fans of the way they sound. Thanks to a new partnership between PSB Speakers, MQA, and Sonical, that could be about to change in a big way: the threesome is planning to launch the world's first set of wireless headphones that use ultra-wideband (UWB) technology instead of Bluetooth, in the first quarter of 2024.

The PSB M4U8 wireless headphones don't have UWB, but they could be the starting point for the first UWB model. PSB / PSB

CES 2023: Audio-Technica adds a mic to its iconic M50x headphones to target creators

Audio-Technica showed live streamers and content creators that it's been thinking about them at CES 2023, today unveiling StreamSet, two new models of wired streaming headsets based on the iconic M50x professional monitor headphones that come with the added bonus of a built-in condenser microphone.

Dubbed by Audio-Technica as the "world's first streaming headsets," two models are available, and unlike the M50x, they're both hard-wired. The analog ATH-M50xSTS comes with a two-meter cable with a 3.5mm headphone input (and a 1/4-inch adapter, too), plus a 3-pin XLR for connecting the mic to a mixer or compatible audio interface. The digital ATH-M50xSTS-USB, as its name implies, has a USB-A cable (also two-meters in length) with a USB-C adapter for direct connectivity to computers. The STS-USB model has a built-in digital-to-analog converter (DAC) with a sampling rate of up to 24-bit/96 kHz, and a feature that lets you hear your vocals in the headset and control the volume with a dial that sits on the earcup. Otherwise, both models are pretty much the same.
