FREETALK Wireless (2nd Gen) in the house!  Literally.

FREETALK Wireless
Along with a couple other little gadgets, the FREETALK Wireless headset arrived in the mail from InStoreSolutions (ISS). This product – before even getting into it – holds a special place in my heart, as it uses a chipset from Avnera that I helped design and target at precisely this usage model. That all started six years ago... but amazingly enough this is the first 2nd Generation model to emerge from one of the chipset's adopters. The other first generation products from Logitech, Plantronics, and Creative are still out there, and going strong (save for Creative's which is hard to come by... unfortunately because their mic boom was h-o-t).

Cracking the box open, plugging it in... all worked without a hitch. Devices were paired out of the box, so no setup, and plugging it into the MacBookPro was seamless. Plug and Play, as usual, painless.

The high points

Compared to the first generation FREETALK, the new model is more comfortable, sports a folding design, and comes with a protective and compact carrying case. Definite improvements. The mic boom is the same variety that Creative used, and so it is awesome in feel and manipulation, however the mic tip itself is kinda chunky and blah.

While heating my dinner in the microwave, there was slight interference, but no interruptions... just some warbling and slightly chirpy distortion which is a result of the error concealment algorithms employed by Avnera. To further make life difficult for the FREETALK, there was WiFi active in the same room, as well as one other AvneraAudio device sending audio within my home-theater space. Basically, it's nice to see after a couple years, the wireless audio chipset holds up to even some pretty insane usage stress.

Range performance was particularly good on the model I received. I easily had 45 feet through two walls. Slightly better than the Plantronics .Audio 995 I usually use, and where my head position can cause drop outs when I am on the other end of the my space. Nothing of the sort with the FREETALK. I'm sure the manufacturer has taken their learnings from building the first generation model which always helps maintain RF performance and consistency. It's not unusual for a high level of variability to plague wireless performance on one piece versus the next. It's maddening for makers, and more important those poor users who get stuck with one... just make sure you save your receipts for a day or two.

Switzerland

A few points to note regarding this model that I am fairly neutral about. This second generation FREETALK Wireless has a proper dongle without the wire tethered "puck" of the the first generation model. I guess I like it for cleanliness sake, but it also bugs a little me because I am always worried I will wrench it while plugged into my MacBook Pro.

I noticed the addition of microphone sidetone added into the headphone audio – something the Logitech had, and I personally could care less about.

The other aspect of this model I could take or leave is the new style.   The design has a very generic industrial design on the cups, and if I had to sound negative here in Switzerland, the silkscreening was a bit garish and clumsy looking.

My one (real) disappointment

Where this particular model really fell short of its pioneering predecessors was in the sound quality – both in tonal aspects, and in audible noise level.

To my ear, the 2nd Gen FREETALK sounds a little tinny and less precise than the Logitech and Plantronics models, and perhaps even less forgivably, worse than the 1st Gen FREETALK (which trumped them all to be frank).  I am disappointed that ISS didn't follow through on the most stealthy, audio value device in this space.

The second issue is noise. When there is nothing playing through, there is an audible amount of noise to be heard. A shame, and a blemish on what could be a much better SNR given the core system employed. I admit I'm a little more critical than most, and it's really only noticeable when music isn't playing... but as a hint to technical folks associated with this product, the noise I am hearing does not change with the volume level of the headphone DAC which (I think) means that the audio is coupling into the speakers themselves directly from the circuit itself.

Again, all three models I've used extensively before this did not exhibit this noise problem, which to me is a factor of the maker and product development decisions made while bringing this product to market.

Hopefully some tweaks improve this as production moves forward, or perhaps I had a bad unit in some respect.

Overall

For US$79.99, this product is a considerably good value for the features and experience it provides.  It's no secret my personal favorite Avnera-based headset is the Plantronics .Audio 995, but considering the latest FREETALK gets better range, is more compact and carry-friendly, and assuming they can fix the one needling audio quality issue, I would say it's a toss up between these two models.

Many users stand to be very satisfied. It's also great that ISS has stepped up their support levels and so much user frustration from the early days of the first model will be addressed in a better manner going forward.

The leader of the pack (imo).

The Plantronics take on Avnera's first gen AudioMagic chips seems to capture the yellow jersey.  Logitech, Creative, and Freetalk may very well still be selling at a strong clip, but the feature set and execution of the .Audio 995 seems to resonate with consumers more than the others – who admittedly are getting long in the tooth.

Just ran across these user reviews over at Amazon, and they made my day, and so I think they are worth reading...

From Chris Zee Shutterbug:

Let me start with something that amazed me. I plugged the USB dongle into the computer, started Itunes, hit play and music started coming from the headphones!!! I did not have to configure a single thing. [...] That level of ease of operation has to be commended.

From Jennifer:

I love these headphones. I got them for my teenage son, but when he told me to listen to the great sound they became mine! The sound quality is incredible. [...] My son used them for World of Warcraft and he said the sound was awesome. He wants them back...but I've found a great hiding place and I am keeping them!

From CR Swanson:

I've reviewed three different headphones for Amazon Vine, including the three-hundered dollar Monster Beats, and this is, by far, the best of the bunch. They're comfy, they have great sound quality and the wireless mode just can't be beat!

From P Colin McGraw (with a gripe for balance):

I usually use wired headsets, and it feels freeing to be able to walk around the room listening to music, not having to navigate to iTunes with my mouse to fast forward as I get tangled in a headphone's cord. In fact, I'd actually use this headset even if I didn't need a microphone for just the awesome wireless headphone capabilities!

If I had to dig deep for a negative, I guess it would be the comfort. [...] the pads on your ears are designed to go ON TOP of your ears instead of AROUND them. It basically smooshes your ears to the side of your head, which you don't mind at first with the soft pads, but it gets uncomfortable after awhile.

Overall, it's hard to find a flaw with these and I'd wholeheartedly recommend them to anyone looking for a headset with or without a mic! It would be hard to design this headset any better and it's a great value!

There is another review, that gave 2 out of 5 stars (when 4/5 is the average over 8 reviews) – feel free to check it out – but from what I know of our technology, he is experiencing a busted antenna, probably a maunfacturing defect...  No other reason why he'd be getting garbagey sound while he moves.  Also, the output power of the headset compared to a 2.4GHz cordless telephone is not even close!  So if he is looking for a source for his wireless-G woes.. he should direct his attention elsewhere.  That's the spectrum monster.  Also he should switch to Skype and junk the 20th century technology.

Vizio Soundbar (VSB210WS) available now... goodness within

150sq_vizioThe Vizio Soundbar (VSB210WS) is finally available!

Go get it now!  See Walmart and Sears.  Or check out more info at Vizio's homepage.

Warning.  What you are about to read is a biased, but pretty informed review.  I encourage you to check out reviews from other parts of the internet, and I will also link as many as I find here at wirelessaudioblog... so over the coming months, check out the rest of this site for more recent infos...

OK...

Pros: Wireless subwoofer, Avnera wireless, Avnera class-D, support for (forthcoming) wireless headphones

Cons: At $349, be ready to spend over a $1000 because you're gonna want a few for your house.  You will wake your neighbors.

The VSB210WS uses two of Avnera's core technologies.

The first technology is the wireless system that is employed in devices like the Logitech Clearchat PC Wireless, the Rocketfish RF-WS01 and RF-WS02, the Rocketfish RF-WHTIB, and countless others.  The Vizio Soundbar uses Avnera's wireless system for a high-performance, wireless subwoofer. There is also future-ready support for wireless headphones (with SRS action as well).  This is a killer feature that you won't see on any other soundbar on the market...the wireless system will drive up to three wireless headphones simultaneously, and when activating the headphones, automatically mutes the speakers.

The second of Avnera's technology put to work is their Class-D amplifier solution.  Avnera's Class-D is finally ready for showtime and it's gaining traction in the industry due to its affordability, high power-efficiency, and extremely low distortion performance.  In fact, Avnera's Class-D is patented and pretty much bad-ass.  The fundamental advantage is the patented PWM driver stage that delivers very high PSRR (power supply rejection ratio) performance.. thus allowing Avnera-based powered speakers to run on lower-grade, switching power supplies, without encountering increases in distortion or noise at the audio output due to power supply noise.  It also has a scalable power output stage that enables it to serve low power, low-cost device as well as higher-power premium offerings... all the while maintaining hi-fi quality and affordability.   As a result, Avnera's amp is finding duty in a broad range of affordable consumer devices, like the Rocketfish RF-WS02 and entry-level products like the iHome iP27, and premium products like Vizio's offering and iHome's iP1 which is due to hit later this season.  In the Vizio Soundbar, the amplifier drives both the bar AND the subwoofer.  You really just gotta hook this bad boy up and hear the difference.

Also enjoy the implementations of SRS TruSurround HD and SRS TruVolume running on a dedicated Cirrus DSP (I think... need to dig back thru FCC teardowns to verify).

Q: What are the best headphones for use with Skype? - Scobleizer

A: Any headset that is wireless, and running on Avnera.

I love it when guys like Robert Scoble ask a question that there is an easy answer to... :-)

"Heroes" snippit starring Avnera-enabled product...



Here is the clip from last night's Heroes starring the Logitech Clearchat PC Wireless.

A few notes:

  • Lack of logos on the headset means that Logitech is not as cool of a brand as Apple... or the studio isn't getting paid by Logitech to place the product...  no news here really... just interesting.

  • Ando is wearing a gen 2 Jawbone headset incorrectly...  the vibration sensor isn't resting on his cheek, meaning there is really little chance that the thing is working well.

  • For all the miracles the Clearchat is capable of, noted all over this blog, it apparently could not prevent Hiro from getting his ass kicked.
