ASUS Wireless Portable Stereo Speaker (SP-BT23)
A portable and convenient wireless portable speaker.
- Bluetooth with A2DP, good battery life, can take advantage of its surroundings to improve sound quality
- Could be smaller, woofers are unprotected while in use, sound quality isn't great
ASUS' SP-BT23 doesn't deliver particularly good sound, but it has a good battery life and Bluetooth connectivity — a decent trade-off.
Price$ 129.00 (AUD)
Combining wireless connectivity, a high level of portability and decent battery life, ASUS' SP-BT23 speaker is a decent option for listening to music indoors or outside. Its sound quality leaves much to be desired, but it is very convenient.
The SP-BT23 offers analog sound through a standard 3.5mm jack and Bluetooth support with Advanced Audio Distribution Profile (A2DP) capability. It can be powered by either a 12V adapter or four AA batteries. The speaker is coated in gloss white plastic, with black plastic surrounding the woofers. At 123.5mm, the SP-BT23 is quite tall for a portable speaker.
During transport, the SP-BT23's dual 1in woofers are protected by a plastic cap with a removable rubber insert. When using the speaker, this cap can be placed on the bottom of the speaker to aid the ported subwoofer. Unfortunately, there is no grill or similar protection for the woofers when the cap is removed.
The slight curvature of the case near the woofers allows the speaker to sit flat or be stood upright.
The environment and placing the cap on the passive subwoofer (or not) affect the sound quality and frequency biases of the speaker.
When placed in its most logical position — standing up with the provided cap placed on the bottom — the SP-BT23 has a slightly tinny sound, and no real lower mid-range or bass frequencies. Standing the speaker up and facing it towards a nearby wall makes the sound much more biased towards bass. The SP-BT23 doesn't provide the best sound quality, even taking into account its size and price, but its design helps it take advantage of its surroundings to improve audio.
The SP-BT23 is highly portable and has a long battery life. When testing the speaker at the loudest possible distortion-free volume level through the 3.5mm cable, the SP-BT23 lasted a total of 18 hours; this falls short of Altec Lansing's orbit MP3 (IM237) but is still commendable considering the speaker's size. Equally surprising was the device's ability to play streaming audio from a Bluetooth device for a total of 15.5 hours.
The speaker's Bluetooth connectivity works quite well. Pairing the speaker with a notebook or mobile phone works just like Bluetooth headphones, simply requiring users to put in the default PIN code and change the audio settings if necessary. The SP-BT23 can be placed up to 15m from a paired device, though walls and obstacles will affect the maximum possible range.

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.
I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.
As a freelance writer who is always on the go, I like my technology to be both efficient and effective so I can do my job well. The HP OfficeJet Pro 8730 Inkjet Printer ticks all the boxes in terms of form factor, performance and user interface.
I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.
Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!
For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
