Right hook British firm Atomic Floyd's AirJax Titanium2 headset (below) comes with adjustable ear hooks similar in design to those used by Bang & Olufsen. The FlexiFit ear hooks are built with a highly elastic smart alloy that offers 'superior comfort and durability'. The headset delivers outstanding bass-rich audio, thanks to a sound power system and a high-quality 3.55mm audio jack. The headset comes with a hard-to-tangle fabric audio cord, a double-stitched protective leather pouch and an aircraft adapter. The AirJax Titanium2 sells for HK$1,780. Neat tricks The only cable used with Sony's high-performance DAV-TZ210 home-theatre system (above) is for power. The company's advanced S-Air digital wireless-transmission technology ensures a tidy set-up. So-called digital cinema auto-calibration detects where the speakers have been placed to calculate volume and frequency settings for optimum sound. The system comprises a main unit with equaliser, DVD/CD player and amplifier functions, a subwoofer and five compact satellite speakers. The DAV-TZ210 home-theatre system is priced at HK$2,880. Own strength Sha Tin-based Aztech Systems has created a device that stabilises home Wi-fi networks. Plug in the HL110EW Wireless-N HomePlug (right) and it will eliminate disruptions to your home broadband router due to weak wireless signals or blind spots. It works with any brand of internet-linked high-definition set-top box, games console, digital camera, laptop or smartphone. The device consumes less than seven watts of power - far less than that needed to run a typical coffee maker. The HL110EW costs HK$699.
