Recently, to prepare for a long plane flight I bought a pair of Sony MDR-1000X Bluetooth noise canceling headphones. While I won't get into the specifics of these headphones other than that I have been really satisfied with them, when I returned from my trip I wanted to start using them at the office.
Seemingly that would be easy, as these headphones feature a 3.5mm input, but I am frequently walking around the office and I wanted to fully utilize the wireless features. While I could have just used any Bluetooth adapter compatible with Windows, I wanted to test out one of the features of these headphones — AptX technology.
AptX is an alternate Bluetooth audio codec from Qualcomm which aims to feature higher audio quality. Sebastian took a look at a pair of AptX-enabled headphones earlier this year, and I have wanted to check out the technology ever since.
After receiving the USB adapter, I first installed the CSR Harmony software from the Azio website. This is a piece of software that sits on top of the Windows Bluetooth Stack and enabled advanced Bluetooth features, including AptX, on certain Bluetooth chipsets.
Once the software was installed, I plugged in the device and found a new Bluetooth icon sitting in my Windows tray.
From here, you can simply right click the icon and search for a new Bluetooth device.
Once I put the headphones into pairing mode I was able to pair to them successfully.
And, that's it! Once you are successfully paired to an AptX device, you should see this popup from the Windows tray confirming that AptX is working. From here, you can use the headphones just like you would with any Windows audio playback device.
This certainly isn't a review of AptX audio quality, I will defer to Sebastian's analysis for that in which he calls the headphones he tested "audiophile-approved Bluetooth."
For a $12 investment, it seems like a no-brainer for users who already have an AptX-enabled device that they use on their smartphone.

Today Qualcomm took the covers off of an update to the Snapdragon 600 family of processors, now known as mobile platforms. The Snapdragon 660 and 630 Mobile Platforms are important products in the company’s portfolio as they address a larger segment of the consumer market than the premium-tier Snapdragon 800 while still offering performance and feature sets above the budget segments of the 400s. The Snapdragon 820 and 835 traditionally get all of the attention from media, the 600-series is at the heart of popular devices like the Sony Xperia X, Asus Zenfone 3 Ultra, HTC 10 Lifestyle and over 1000 more designs.
The biggest changes to both new platforms come in the form of LTE connectivity and GPU performance. In a bid to bring previously unseen capabilities to the 600-series of solutions, Qualcomm has taken the Snapdragon X12 LTE modem that shipped with the Snapdragon 820/821 SoC and integrated it on both the 660 and 630. This creates mainstream mobile platforms that can run Cat 12/13 modems and speeds as high as 600 Mbps downstream (3x carrier aggregation) and 150 Mbps upstream (2x carrier aggregation).
That is a significant move and should result in a massive amount of high speed devices saturating the market (and carriers’ networks) starting later this year. Along with that higher performance comes the same X12 feature set that we saw with Snapdragon 820/821 including adaptive antenna tuning capability (TruSignal) and dynamic signal quality adjustments for power efficiency optimizations.
The GPU performance of both the Snapdragon 660 and 630 get a boost over the previous competitors (653 and 626 respectively) though they do so with different Adreno implementations. The SD 660 uses the Adreno 512 GPU that offers up to 30% better performance compared to the Adreno 510 used on the SD 650 series. While we don’t have details yet on where that advantage comes from (clocks or core improvements), I have a feeling that much of it comes from improved frequencies. The Snapdragon 630 uses the Adreno 508 GPU, compared to the 506 from the SD 626 processor, and also claims to have a 30% performance advantage over the previous generation.

Microsoft has announced their new Surface Laptop, which notably leaked just yesterday, but the surprising part was not the hardware at all - however sleek and impressive it might be. Yes, it seems I spoke too soon with the Windows 10 S news, as this consumer (I assume) product is shipping with that new version of the OS which only allows apps to be installed from the Windows Store.
As to the hardware, it is milled from a block of aluminum (as shown in a very Apple-like video) and the heat pipes for the processor are milled into the bottom case to help make this so thin, but the laptop will undoubtedly feel warm to the touch during use (a fact which was mentioned on stage as a positive thing). The palmrest/keyboard is coated in a fabric material called Alcantara, rather than being bare metal and plastic. The combination of warmth (literally) and the fabric surface is supposed to make the new laptop feel very friendly, as the narrative went.
Thankfully (in my opinion, anyway) the bizarre flexible hinge of the prior Surface laptop is gone in favor of a conventional one - and with it the air gap from he previous design. Among the features mentioned for this new Surface were its PixelSense screen, which is the “thinnest LCD touch panel ever in a laptop”, and a very impressive 14.5 hour battery life. The standby power consumption was described as effectively zero, which suggests that a suspend state of some kind is standard to prevent drain when not in use. rather than a low-power sleep.

Microsoft stated that two versions (Intel Core i5 and Core i7) will be available for pre-order beginning today, with the Core i5 model starting at $999. (Pricing on the Core i7 version was not mentioned.)
Windows Central has posted specs for the new machines, reproduced below:
- Display: 13.5-inch Pixel Sense display, 10 point multi-touch
- Display Resolution: 2256 x 1504, at 201 ppi, Aspect Ratio: 3:2

I will briefly editorialize here to mention the Windows 10 S problem here. That limitation might make sense for education, if Microsoft is providing a suite of apps that make sense for a school, but consumers will undoubtedly want more flexibility from their own devices. This is less consumer-friendly than even the Starter Edition of Windows from the past, which limited the number of running applications but not their provenance.
The Dell Inspiron 15 7000 Gaming series has been part of the increasingly interesting sub-$1000 gaming notebook market since it’s introduction in 2015. We took a look at last year’s offering and were very impressed with the performance it had to offer, but slightly disappointed in the build quality.
Dell is back this year with an all-new industrial design for the Inspiron 15 7000 Gaming along with updated graphics in form of the GeForce GTX 1050 Ti. Can a $850 gaming notebook possibly live up to expectations? Let’s take a closer look.
After three generations of the Dell Inspiron 15 Gaming product, it’s evident that Dell takes this market segment seriously. Alienware seems to have lost a bit of the hearts and minds of gamers in the high-end segment, but Dell has carved out a nice corner of the gaming market.
|Dell Inspiron 15 7567 Gaming (configuration as reviewed)|
|Processor||Intel Core i5-7300HQ (Kaby Lake)|
|Graphics||NVIDIA Geforce GTX 1050 Ti (4GB)|
|Memory||8GB DDR4-2400 (One DIMM)|
|Screen||15.6-in 1920x1080 I|
256GB SanDisk X400 SATA M.2
Available 2.5" drive slot
|Camera||720p / Dual Digital Array Microphone|
|Wireless||Intel 3165 802.11ac + BT 4.2 (Dual Band, 1x1)|
3x USB 3.0
Audio combo jack
|Dimensions||384.9mm x 274.73mm x 25.44mm (15.15" x 10.82" x 1")
5.76 lbs. (2620 g)
|OS||Windows 10 Home|
|Price||$849 - Dell.com|
Let's just get this out of the way: for the $850 price tag of the model that we were sent by Dell for review, this is an amazing collection of hardware. Traditionally laptops under $1000 have an obvious compromise, but it's difficult to find one here. Dedicated graphics, flash Storage, 1080p screen, and a large battery all are features that I look for in notebooks. Needless to say, my expectations for the Inspiron 15 Gaming are quite high.

Razer updated their Blade gaming laptop with a GTX 1060 and i7-7700HQ along with a bump in the 16GB of memory to DDR4-2400 and an 256GB M.2 Samsung PM961 SSD. That is not what makes this review from Kitguru interesting, it is the additional product which came with the Blade that does. The Razer Core is a housing for an external GPU which connects over Thunderbolt 3. You can install either an AMD or NVIDIA GPU which 310mm or less in length which can be powered by a 500W PSU, which is pretty much any GPU on the market. Kitguru installed a GTX 1080 and compared the performance of the integrated GTX 1060 to the higher end card; you can see the results here.
"We began our recent review of the 2017 Razer Blade by telling you that Razer had updated the graphics chip from GTX 970M to GTX 1060. The laptop has continued to evolve and now it’s the turn of the CPU which has been changed from Intel Core i7-6700HQ Skylake to Core i7-7700HQ Kaby Lake."

Tagged: X20, t-mobile, spectrum, qualcomm, LTE, Gigabit LTE, FCC, Carrier Aggregation, 600mhz, 5G
This afternoon, T-Mobile's ardent CEO John Legere announced the results of the FCC's recent spectrum auction concerning the low-band 600MHz range. In a $7.99 Billion deal, T-Mobile is set to gain 45% of all of the low-band spectrum being auctioned.
T-Mobile is quick to point out that the spectrum they purchased covers 100% of the United States and Puerto Rico, with a nationwide average of 31 MHz of spectrum acquired. Having this wide of a range of spectrum available nationwide will help T-Mobile with their rollout of Carrier Aggregation, on the road to Gigabit-Class LTE and 5G.
This acquisition wasn't without help from the FCC however. In 2014, when the FCC decided to auction off the spectrum that was previously used for broadcast TV, they decided to set aside 30MHz of the available 70MHz specifically for carriers that did not currently have large holdings in low-band spectrum. This means that ATT and Verizon, who both operate large LTE networks in the 700MHz range were excluded from part of the spectrum being auctioned off.
Low-band spectrum in strategically important for LTE rollouts in particular as it can travel further and works better indoors than high-band offerings like Sprint's large available spectrum in the 2.5GHz
While it usually takes a significant amount of time to see the results of newly acquired spectrum, T-Mobile promises significant network expansion by the end of 2017. Legere claims that over 1,000,000 square miles of the newly acquires spectrum will be cleared for use by the FCC by the end of this year, and put into production by T-Mobile. T-Mobile plans to use this spectrum to both expand LTE coverage into new markets as well as strengthening their coverage in existing markets to provide more speed and greater density of coverage.
However, there is one side of the 600MHz equation that is out of the hands of T-Mobile, the user equipment. Currently, there are no shipping LTE radios capable of operating in the 600MHz range. Qualcomm has announced that their in-development X20 LTE modem will work with 600MHz, but we have no timeline as to a possible release of devices with the X20.
Hopefully, we don't have to wait too long for user devices capable of 600MHz LTE operation, it would be a real shame to have a newly expanded T-Mobile network that no one can connect to!
The road to Gigabit-class LTE and subsequently 5G seems to be a fierce one, and we look forward to seeing developments from competing carriers.

The new LG G6 sports a 5.7", 2880×1440 IPS LCD powered by the aging Qualcomm Snapdragon 821 with a pair of 2.35GHz Kryo cores and two 1.6 GHz Kryo cores. The hardware is going to have a hard time competing against other phones powered by newer chips such as the Snapdragon 835or Exynos 8895. Ars Technica ran the phone through benchmarks in their full review here. The phone itself is attractively made and does offer a wide variety of features, however it will have trouble once the new Galaxy and iPhone arrive on the market.
"The LG G6 seems to be launching in the US at the worst possible time. The phone uses Qualcomm's 2016 SoC—the Qualcomm Snapdragon 821—in 2017, making it already seem dated. The G6 is also launching right as Samsung's hype machine for the Galaxy S8 is revving up."

Tagged: apple, Imagination Technologies, PowerVR
This morning, Imagination Technologies Group released a press statement announcing that Apple Inc. intends to phase out their technology in 15 to 24 months. Imagination has doubts that Apple could have circumvented every piece of intellectual property, and they have requested proof from Apple that their new solution avoids all patents, trade secrets, and so forth. According to Imagination’s statement, Apple has, thus far, not provided that proof, and they don’t believe Apple’s claims.
On the one hand, it makes sense that Apple would not divulge their own trade secrets to their current-partner, soon-competitor until it’s necessary for them to do so. On the other hand, GPUs, based on previous stories, like the Intel / NVIDIA cross-license six years ago, are still a legal minefield for new players in the industry.
So, in short, Apple says they don’t need Imagination anymore, but Imagination calls bull.
From the financial side of things, Apple is a gigantic chunk of Imagination’s revenue. For the year ending on April 30th, 2016, Apple contributed about £60.7 million GBP (~$75 million USD in today’s currency) to Imagination Technology’s revenue. Over that same period, Imagination Technology’s entire revenue was £120.0 million GBP ($149.8 million USD in today’s currency).
To see how losing essentially half of your revenue can damage a company, I’ve included a screenshot of their current stock price (via Google Finance... and I apologize for the tall shot). It must be a bit scary to do business with Apple, given how much revenue they can add and subtract on a moment’s notice. I’m reminded of the iPhone 6 sapphire glass issue, where GT Advanced Technologies took on a half-billion dollars of debt to create sapphire for Apple, only to end up rejected in the end. In that case, though, Apple agreed to absolve the company of its remaining debt after GT liquidated its equipment.
As for Apple’s new GPU? It will be interesting to see how it turns out. Apple already has their own low-level graphics API, Metal, so they might have a lot to gain, although some macOS and iOS applications use OpenGL and OpenGL ES.
We’ll find out in less than two years.

Oukitel is not the most common brand name when comes to smartphones but if you are looking for a device which you can take on the road and depend on it working as long as you do you should take a peek at TechARP's review. Both of these phones contain 10,000 mAh batteries and the Oukitel K10000 Max is a ruggedized model with a polycarbonate and rubber shell to protect it from moisture and unexpected changes in velocity. They come with Android 7.0 and run ARM A53 chips with graphics powered by a Mali-T860 MP2. They may not be as pretty as some phones but they will outlast them when being used.
"We managed to get our hands on two Oukitel smartphones with 10,000 mAh batteries - the Oukitel K10000 Max and the Oukitel K10000 Pro. Check them out there!"
