This month, two PC World readers are going to be the lucky recipients of Huawei’s latest smartwatch, the HUAWEI WATCH GT 2 Pro, valued at $499.
Harman Kardon GLA-55 speakers
The Harman Kardon GLA-55 is a striking two-way speaker system featuring transparent cabinets and bi-amped drivers with digital crossovers.
- Great audio quality, visually appealing design
At around $1000, the GLA-55 speakers sit at the high-end for iPod audio. The money buys something of an artwork in the speakers' unique design alone, but there's also some smart acoustic engineering at work here. A combination of powerful amplification, clever DSP and very solid, irregular-sided cabinets mean the sound can even surpass traditional hi-fi amplifiers and loudspeakers systems of a similar price too.

Some speakers are destined to blend discreetly into your environment. Not so the Harman Kardon GLA-55, whose multi-faceted-diamond looks are positively shouting for attention.
Each Harman Kardon GLA-55 speaker is based on a traditional two-way driver design, comprising a concave metal 52mm mid-bass driver and metal-domed tweeter, shoehorned into a totally transparent case resembling an alien crystal skull.
The tweeters carry chromed bars to discourage idle prodding of the delicate domes. And built into the case are the system's amplifiers, hidden away in the base plate.
You connect the speakers to a computer or iPod via a 3.5mm stereo jack plug in the right-hand speaker. Electrical power also comes into this master speaker from a laptop-style power supply. Under the main drivers is a reflex port which helps improve acoustic efficiency and low-frequency response.
As well as the usual volume control on your music player, there are touch-sensitive + and - buttons on the right Harman Kardon GLA-55 speaker, sat between drive units. White LEDs are hidden in each speaker's base, pulsing when in standby mode and steady-on when in use.
Try to lift a Harman Kardon GLA-55 speaker and you may be surprised at their weight. They really are very solid and hefty feeling. If you peer inside the transparent sides you can see the U-shaped reflex port curving through the bodies up to the tweeter, as well as polished metal internal parts of all the drive units. What you can't see is any obvious cable wiring, as this seems to be handled by thin metallic rods that join the drivers.
The GLA-55 speakers not only look but feel like no traditional hi-fi speaker. They are incredibly dense and seem non-resonant. The absence of wood cabinet and parallel internal walls means the familiar colourations of a hi-fi box speaker are entirely absent. In fact, the crazy shape with faceted external sides and curved interior really should reduce the usual resonances that can cloud the sound.
Digital Signal Processing
To optimise sound quality, the GLA-55 system uses digital signal processing (DSP).
Analogue audio signal input is converted to 24-bit/48kHz digital, then passed to a 24-bit DSP, responsible for equalisation and dynamic limiting, gently contouring bass and treble levels to suit the speaker's limited size.
Some compression and limiting here also serves to prevent either the amplifiers or drive units from being overdriven into gross distortion at high volume levels or when presented with high levels of bass.
Four separate channels of 26-watt MOSFET Class D amplifiers are included, two for each speaker and dedicated to each treble and mid-bass drive unit, with active crossovers to split the signal at the DSP stage.
Sound quality of the Harman Kardon GLA-55 is, ahem, clearly impressive. Despite their modest size - by the standards of regular hi-fi loudspeakers, rather than iPod docks - the GLA-55 speakers sound much bigger and fuller than you might expect.
There's no proper subterranean bass of course, yet the subtle tailoring of sound by Harman Kardon's engineers means you do get a great sense of a weighty low-frequency response. Class D amplifiers are rarely lauded by audiophiles, but in the context of these Harman Kardon GLA-55 speakers we still heard a clean and impressively accurate rendering of music.
In music with little bass content they could sound a little clinical, a result of the relatively neutral voicing and 'digital' amps, along with low-resonance cabinets that aren't adding much of their own unwanted signature. A retro valve amp sound is not in the Harman Kardon GLA-55's repertoire. But they can do well-paced dance and pop very well, never sounding strained or stressed even when propelling bass from their long-throw drivers.
Top frequencies could be a tad metallic in character but this was tempered by strong bass fundamentals and a midband that neither unduly projected vocalists nor left them shy at the back of the mix.
Compared to another top-spec PC/iPod speaker system, the Bowers & Wilkins MM1, the Harman Kardon GLA-55 speakers don't show their inner digital processing quite so much when limiting dynamic peaks. And top volume is also noticeably expanded. At close to twice the price of the B&Ws, the expectation may be for a more mature and encompassing sound. And for that expanded sound quality with incredible freedom from chestiness they will not disappoint.

Ultimately this laptop has achieved everything I would hope for in a laptop for work, while fitting that into a form factor and weight that is remarkable.
This smart laptop was enjoyable to use and great to work on – creating content was super simple.
It really doesn’t get more “gaming laptop” than this.
As the Maserati or BMW of laptops, it would fit perfectly in the hands of a professional needing firepower under the hood, sophistication and class on the surface, and gaming prowess (sports mode if you will) in between.
The MSI PS63 is an amazing laptop and I would definitely consider buying one in the future.
This small mobile printer is exactly what I need for invoicing and other jobs such as sending fellow tradesman details or step-by-step instructions that I can easily print off from my phone or the Web.
