    3.00 / 5


  • Reasonable clarity, decent mid-bass


  • Cheap construction, poor fit and low clamping force, open design leaks sound and reduces ambient noise reduction, distortion at higher volumes

Bottom Line

As one of the cheapest pairs of full-size headphones available, TDK's ST-PR300 has surprisingly competent sound reproduction at moderate volumes. For a street price of a little more than $20, these headphones offer decent treble clarity and reasonable mid-range response. It's not all good news, though -- build quality is poor and the headphones leak sound badly.

Would you buy this?

TDK's ST-PR300 full-size headphones are one of the cheapest pairs on the market. At moderate volume levels there is decent detail evident in treble and mid-range frequencies, but the headphones' low price is evident in their high volume performance and the mediocre build quality and fit.

We connected the TDK ST-PR300 headphones to a PC to see how they functioned when streaming low-quality music and playing games, and also gave them a run with an Apple iPhone 3GS. At low and moderate volume levels the TDK ST-PR300 headphones performed better than we expected. A small amount of fine detail is audible in the treble of audio, and most high-frequency sounds are crisp and clear. Mid-range is also well accounted for thanks to competent 40mm drivers. There is little mid-bass to be heard, but overall the sound is reasonably balanced.

At higher volume levels, the TDK ST-PR300 headphones start to struggle. Treble becomes noticeably harsher when the headphones are powered at full volume, and mid-range becomes ragged and loses much of its warmth. While we don't believe this volume level would often be used in a quiet listening environment, we've heard more competent headphones that only cost slightly more.

The clamping force of the TDK ST-PR300 headphones is low, so significant adjustment of the headband is required to get an optimum fit. The open ear-cup design fails to block any outside noise, requiring higher volume levels to drown out ambient sounds. The TDK ST-PR300 headphones also leak sound significantly, so you may annoy those around you if listening at high volumes.

The build quality of the TDK ST-PR300 is mediocre at best, with cheap plastics used for the headband and ear-cups. A rubberised padded headband is comfortable for short periods of wear but we would have preferred the soft suede that the ear-cups are coated with. An in-line volume control along the 2.7m cable allows manual adjustment of audio volume, but it doesn't have a clip for securing it to your shirt or bag strap.

We were interested to see that a 6.5mm (or 1/4in, if you're an imperial sympathiser) mini-jack is included with the TDK ST-PR300 headphones. This allows you to connect the headphones to a whole range of devices such as an audio mixer or professional audio recorder, but we can't think of a scenario where this would actually come in handy — if you have good quality audio equipment then you’ve probably already got good headphones.

TDK's ST-PR300 headphones sound reasonably good for their $39.95 price tag. Their build quality and fit aren’t great but you get what you pay for.

The HP OfficeJet 250 Mobile Printer is a great device that fits perfectly into my fast paced and mobile lifestyle. My first impression of the printer itself was how incredibly compact and sleek the device was.

Wireless printing from my iPhone was also a handy feature, the whole experience was quick and seamless with no setup requirements - accessed through the default iOS printing menu options.

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.
