Apple iphone 6 Pro Concept

It is that time of the year when leaks about the next iteration of the Apple iPhone meld with concept designs for the device. We've seen our share of concept versions of the Apple iphone 6, and this newest one might have some of the highest specs for both cameras and the processor. Of course, when you're dealing with a concept, you can almost make the components whatever you want them to be. And as you will see, you can also create an interesting accessory.

This concept device is titled the Apple iPhone 6 Pro, and features a 3MP front-facing HD camera. The phone is 7.2mm thin, which is slightly thinner than the 7.6mm thickness of the Apple iphone 5S. A notification light is added to the device, but at the bottom of the unit instead of the top. And while Steve Jobs hated the stylus, perhaps he won't roll over too much in his grave when he sees the iStick. This accessory neatly slides into its home at the bottom of the model. On back, is a 16MP Ultra HD Camera. A heart rate monitor is on board.

This iPhone 6 concept slides into a separate device known as the iController, which looks like a game controller from one of today's consoles. Once your phone is docked inside, the iController projects games on the wall. We're not sure how many people would rather view a game on a wall when they can see it on an HD screen on their phone. What might be useful is the holographic QWERTY that is projected. That is something we've seen before in other iPhone concepts. The Apple iPhone 6 Pro is powered by an A9 processor and runs iOS 8. The size of that luscious edge-to-edge screen was not revealed.

Some concepts are developed around a large dose of reality, while others are way out there. This concept you can file in the latter folder

High-quality headphone amplifier for iPhone doubles as a 3600mAh power bank

If you consider yourself an audiophile, and if you also happen to be an iPhone user, then here's an accessory that might pique your interest – the TechFreeR Head-Fi. It is an audio DAC (digital-to-analog converter) designed with iOS devices in mind, made to take your music listening experience to a whole new level. The gadget also doubles as a power bank with a capacity of 3600mAh, so it can also be used to recharge an iPhone on the go. Neat, huh?

So here's how the audio magic happens. The TechFreeR Head-Fi connects to an iPhone, or any iOS device, over its Lightning interface. Digital data is then fed into an AP918 audio processor, which is connected over I2S to a PCM1798 audio DAC. This chip, made by Texas Instruments, supports 96kHz sampling rate at a resolution of 24 bits for an audiophile-grade sound. At the output, a TI TPA6130 chip pumps out 130mW of clear, amplified audio straight into your headphones. 

How do you get one? Well, you can't. At least not yet. The TechFreeR Head-Fi is a Kickstarter project with a goal of 35 000 Canadian dollars, and only a fraction of that has been raised as of this writing. But with over a month until the campaign's end, this audiophile-centric iPhone accessory has a good chance at materializing later this summer. A pledge of 109 Canadian dollars gets you one in either black or silver, which is a pretty good deal given the gizmo's estimated retail price of over 229 bucks. 

Upcoming New Samsung Galaxy K

The Samsung Galaxy K, also referred to as the Samsung Galaxy S5 Zoom, isn't exactly what you'd call a secret. The device – a blend between an Android smartphone and a 20MP point-and-shoot camera with optical zoom – got exposed in photos multiple times over the past few weeks, and its hardware specs are no mystery either.

What we have to share with you today, however, is not a leak. It is an official teaser coming straight from Samsung's Instagram account – an image of the Red Dot Design Museum in Singapore, where "The Next Galaxy" is going to be announced on April 29. Clearly, the teaser hints at a device with superior (for a smartphone) zooming capabilities, and according to what is known so far, the Samsung Galaxy K will offer 10x optical zoom, just like last year's Samsung galaxy S4 Zoom.

Of course, the Samsung Galaxy K (the name has yet to be confirmed, by the way) should be capable of a lot more than just taking photos and videos. It will also be a fully-functional Android smartphone, with a 4.8-inch 720 x 1280 pixel display, a hexa-core Exynos 5 SoC, and 2GB of RAM. Android 4.4.2 KitKat will come pre-loaded, along with Samsung's TouchWiz interface in its latest form. A feature-rich camera application is assumed to be on board as well
