Bowers & Wilkins Expands Into True Wireless with New PI7 and PI5 Models Focusing on Audio Quality
True Wireless Stereo (TWS) in-ear headphones are immensely popular, but Bowers & Wilkins thinks that most currently available designs represent a compromise, one that trades sound quality for wireless convenience. “Bowers & Wilkins has always insisted this issue would need to be addressed before the company could consider launching its own TWS products,” the company states. And they did that with their new PI7 and PI5 true wireless earbud models, where audio quality was the design focus, even though there are also some cool differentiating features. Read More

The Growing Role of Headphones Post-Pandemic
As consumers have spent more time at home throughout the pandemic, headphones really have become an integral device in our daily lives. The global headphones market celebrated a good year in 2020, growing in both volume and retail value, to reach 480 million units and generate $44 billion.

Households have spent more time multitasking - listening to a combination of music, watching entertainment content, and integrating the different aspects of virtual communication involved with home working, home-learning and socializing.

Over the last couple of years, and particularly during the pandemic, we have seen significant overlap in use-cases (office, gaming, health and wellness), which we expect will continue post pandemic. The varied use cases are also merging with the TWS form factor to create new use-case specific segments.
The Adapt 360 EPOS | Sennheiser headphones are designed for the work-from-anywhere age allowing users to stay focused with ANC that reduces background noise, and clear business calls in a solution optimized for UC.
In its latest market outlook report, Futuresource goes on to map out the global headphone landscape, including the new emerging segments that have evolved around these use-cases:

- Office Based Hearables - Products such as Microsoft Surface Earbuds or Jabra Evolve 65t that focus on improved microphone performance, Unified Communications (UC) synchronization and multi-device pairing.
- Hearing Augmentation Hearables with the advent of OTC Hearing Aid regulations, TWS and hearing aids are drawing ever closer and producing products like the Signia Active X. Partnerships such as Qualcomm and Jacoti are also bringing such features to mass-market hearables.
- Gaming Hearables targeted at Mobile Gaming are growing in popularity, particularly in markets in Asia and Eastern Europe, with reduced latency, spatial audio, and mic chat becoming sought-after features.
- Sports & Wellness Hearables – Products such as Frames that focus on open-ear audio encouraging situational awareness. as well as the potential for biometric sensors to monitor vital life signs and provide deeper, smarter health insights.

There are certainly interesting use-cases and categories that are evolving, however these "segment-specific" products are set to remain relatively niche. Conversely, the market points to some of these features finding their way into a "one-product-fits-all" solution. It is likely future products will have to include features that satisfy these specific use-cases, for example including things such as an IPX4 rating, gaming modes, improved microphone capabilities, compatibility to video conferencing software, conversational enhancement, sound personalization features, or biometrics.

2020 and Beyond for TWS
COVID-19 has accelerated the demand for True Wireless Stereo (TWS) earbuds. These devices have improved significantly in terms of connectivity and battery life and are able to satisfy multiple use cases, which benefited its uptake during the pandemic.

The growth in demand for TWS was also driven by the decision of major smartphone brands to drop the headphone jack and now lack bundled-in-the-box wired headphones. However, the growth of TWS is at the expense of other form-factors such as wired models and on-ears, which have continued to see rapid decline.

Futuresource concludes that 2021 is expected to be another year of growth, with smartphone brands dropping bundled headphones and travel retail reopening as we return to the "new normal." Growth is also expected from China, as well as other developing regions where TWS has become more affordable.

Measurements Rate New SMT Low-Voltage JFETs Under Consistent Conditions - An Update Using Modern JFETs
By Dimitri Danyuk
In 2013, Dimitri Danyuk wrote an article that presented apples-to-apples test results for noise densities for several low-noise discrete, SMT, and n-JFETs. In this follow-up article, Danyuk brings us new measurements, updating his design note with measurements of JFET components that appeared more recently on the market. The tests on devices from Linear Systems and ON Semiconductor used the same operating conditions so that designers can make a fair comparison for their applications.
