Dual-driver M4U 4 earphones promise perfect listening room audio experience

For its first foray into a crowded earphone space, PSB Speakers is aiming straight for the audiophile jugular with a combination of hybrid dual-drivers and its own Roomfeel technology. When the source audio signal reaches each M4U 4 in-ear monitor, the lower frequencies are directed to a dynamic driver while the higher end head for a balanced armature driver. This hybrid system has allowed the company's designers to add back the acoustic signature of a typical listening room for greater space and true-to-life presentation of recorded music.

Astell&Kern launches hi-res, high price AK380 audio player

Many of us enjoy listening to a good tune or two when out and about, and a goodly proportion of that mobile music will likely be sourced from a smartphone or tablet. For those who prefer high quality sounds though, dedicated players like Neil Young's Pono and those from iRiver's Astell&Kern are probably going to be on the menu. The latter has announced a new flagship portable audio player aimed squarely at audiophiles and sound professionals, which is capable of 32-bit/384 kHz bit-to-bit decoding without the need for conversion but comes at a rather high cost.

Review: The T10 in-ear headphones from RHA

In November last year, British headphone maker Reid Heath Audio (RHA) released a new flagship in-ear headphone model called the T10i that featured interchangeable tuning filters which altered the frequency response from the company's reference signature to focus on either lows or highs. The high fidelity, noise isolating earphones went on to earn the company a Red Dot Award in the Product Design category. RHA has recently added a sibling that's sonically the same but doesn't have an inline control and is a little cheaper, and it's this T10 model that Gizmag has been taking for a test drive. Read More

"Nano-pixels" hold huge potential for flexible, low-power, high-res screens

The Retina displays featured on Apple's iPhone 4 and 5 models pack a pixel density of 326 ppi, with individual pixels measuring 78 micrometers. That might seem plenty good enough given the average human eye is unable to differentiate between the individual pixels, but scientists in the UK have now developed technology that could lead to extremely high-resolution displays that put such pixel densities to shame.

What shall we do with a neutron microscope?

Neutrons have a set of unique properties that make them better suited than light, electrons, or x-rays for looking at the physics and chemistry going on inside an object. Scientists working out of MIT's Nuclear Reactor Laboratory have now invented and built a high-resolution neutron microscope, a feat that required developing new approaches to neutron optics.

The room with 260 million surfaces: 3D printed architecture is here

Thinking big is no challenge for architects Michael Hansmeyer and Benjamin Dillenburger; they've created a 3D printed room using algorithms to design its intricate cathedral-like interior. Assembled out of 64 massive sandstone-like parts printed out with a huge 3D printer, the room contains 260 million surfaces printed at a resolution of a tenth of a millimeter. The 11 ton room took a month to print but only a day to assemble. The revolutionary fabrication methods the duo used to print the room will, they believe, open the door to printing architecture, freeing architects to create new unimaginable buildings and also restore old ones.
