The Aventho looks like a fairly conventional supra aural (on-ear) headphone. Also, fairly conventionally, it offers Bluetooth wireless connectivity. But it also features an interesting accompanying app that is unconventional, but extremely valuable.

Once upon a time, the trajectory of a piece of consumer electronics was arbitrarily ballistic. Much like a cannonball that leaves the muzzle, flies through the air, and lands, a product was manufactured, sold to a consumer, and dumbly performed its appointed functions. Now, and particularly with products like Alexa, when a consumer product enters a home. it's more like adopting a pet, or more accurately, like taking in a puppy that has a doctorate in statistics.

Let's see a show of hands. How many of you often listen through headphones? Thanks to that camera looking back at you from your device, and some pretty cool software I got from a guy in Russia, I can see that many of you do indeed listen through headphones. You can put your hands down. My question then, is why aren't you listening to binaural recordings?

As Mark Twain (and other others) have noted, “There are lies, damn lies, and statistics.”

Blu-ray looks a zillion times better than DVD, right? Are all of those British viewers blind, or are we asking the wrong questions?

Blue Microphones is well known as a maker of - you guessed it - microphones. It’s been in that business for 20 years. It has more recently entered into the headphone market with the Mo-Fi powered headphones and has now debuted the Lola headphone.

I have issues with Bluetooth. I see it as a force of nature, a veritable tsunami, against all that good sound quality stands for. That is because that oh-so-convenient wireless link limits functionality and degrades audio fidelity. Now, with the advent of the 5.0 spec, Bluetooth is poised to expand its dominance. But, the spec also has a glimmer of hope for us audiophiles.

You’ve seen the ad on TV. The little boy is playfully offered the keys to his dad’s Subaru. But then he imagines all the hassles of driving; stuck in traffic gridlock, he cries out in frustration, “You’re killing me!” That exactly describes my attitude toward the rise of Bluetooth headphones.

It’s a presidential election year in the United States (did you catch the debate last night?), and some of us are unhappy with our electoral choices. But things could be worse—much worse. Take the old Soviet Union, for example. Choices in this totalitarian state were extremely limited, to say the least. During elections, there was one name on the ballot, and the candidate received 99 percent of the vote. On the bright side, the comrades, at least the subversive ones, had bone records.

You probably saw the news reports last week. A lawsuit has been filed against Bose, alleging its Connect app, such as used with a Bose headphone, collects information on the listening habits of the user, without adequately informing the user of the full extent of the practice. The story was widely reported. The rebuttal by Bose was not so widely reported.

"I think we should just be friends."
"You're going to make someone really happy someday."
"We should start seeing other people."
"It's not you, it's me."

The War to End All Wars, finally, is over. The world breathes a sigh of relief. But what if, impossibly, there is another war? What if that new form of warfare, aerial warfare, is again unleashed against Britain? Surely we must prepare a defense against it. A sonic defense.

Your phone has a 100 million-times more computing power than the Apollo guidance computer that landed men on the moon! How many times have you heard that? In fact, that is probably a reasonably true statement, and perhaps even underestimates just how powerful today's phones are. But one thing hasn't changed much since 1969, or even since its invention in 1925 - the dynamic loudspeakers in the astronaut's helmet headsets.

Alert readers will recall that I recently chatted up the idea of building your own computer. Unlike most of my words, these were not idle. I needed a new computer for work on book projects, and I was also intent on finding a solid-state home for all my Compact Discs. So, following my own advice, I built a PC.

Gee, who could have predicted this? The Internet is creating entirely new industries, and decimating others. Big-box electronics retailer Best Buy is among the latest bricks and mortar companies to be decimated by the web.

Aereo, as you'll recall, collected over-the-air TV signals and distributed them to its subscribers via the Internet. With any kind of web access such as a browser, phone, tablet or connected TV, you could access a cloud DVR and watch content anywhere. But, as you may also recall, that business model was judged to be illegal. Aereo had its plug pulled. But now, TiVo is working to revive an Aereo-type model.
