Slot the Opera S5+ around your neck, pop in the earbuds (which have volume and track control), plug the transmitter into your iPod/Touch/Phone/Pad and you can enjoy your music without all that ugly cable nonsense.

Bluetooth earphones, whether you love them or hate them, are, seemingly, here to stay with new designs and models hitting the market every week. So, amidst all this competition, how do the Opera S5+ Bluetooth earphones for the iPhone, iPod Touch and the iPad shape up?.
Opera promise not one, but two things: no dropouts and better than Bluetooth sound – CD quality.
Granted, these claims sound a little far-fetched, but after testing we’re satisfied that they aren’t – we didn’t experience one dropout during our testing period and the sound quality of the earphones, which have a frequency response of 20Hz – 20Khz, was superb.

This is quite an unusual product, sold under the Opera brand and distributed by DIP International. This name may be familiar to you; it's the main distribution arm for products using Kleer technology, the Canadian wireless audio technology that's one of the most effective around at the moment.
Total Kleer compatibility
But what is the S5T in fact? An iPod transmitter. This little box has the same female connector as the one you find on iPod docks.
And what's this for? It has many uses. You may for example want to listen to music on your iPod without taking it out of your pocket. Especially if it's an iPhone and you want to take calls at the same time. For this, there's a dedicated dock receiver, the RX1. The same goes for the Digifi ear buds, the Sleek-Audio wireless kit, or the new Sennheiser RS range wireless headphones. All these products use Kleer technology and are compatible with each other. And it works! All you need to do is push a button on the transmitter and receiver to instantaneously synch them up.
In terms of audio quality, no complaints. There's no degradation in sound and it has a decent range. For battery life, as power is drawn from the iPod/iPhone itself, you're only limited by that. The transmitter and receiver are sold together. A way of connecting up your equipment in all manner of configurations.
Verdict
5 Stars – “More and more products are adopting Kleer wireless technology. The S5T + RX1 is a good relay between these various elements for Apple users.”
SlashGear Review - iPad + Kleer = best party music system yet
By Chris Davies on Monday, Apr 19th 2010
The iPad accessory market is on course to mimic the wildly successful iPhone ecosystem, but what are the must-haves? If you’re anything like us you’re a music fan and you want to use your iPad with an existing iPod speaker dock; we’ve just tried out the D&A RX1 iPod speaker dock receiver dongle we reviewed back in February, paired with a Kleer S5T transmitter, and – despite the iPad initially saying the accessory wasn’t compatible – we’re now enjoying our iTunes music (not to mention Spotify and other streaming services) in high quality and with no cords.
Of course, the iPad already has integrated Bluetooth with A2DP support, but then you’re dealing with limited audio quality and the trouble of finding an audio system with Bluetooth itself. Kleer, meanwhile, promises CD-quality audio and the ability to simultaneously pair one transmitter with up to four receivers; you could, for instance, have your Kleer-based headphones paired with the same transmitter, switching easily between private playback or routing audio through your speakers.
What doesn’t work is track control and menu navigation from the speaker dock’s remote. We can adjust volume, but not navigate the iPad’s music; still, since the tablet isn’t actually docked you can simply carry it around and control it directly. It would make particular sense for a party or any sort of gathering, where you could pass the iPad around and everyone have a hand in creating a custom playlist. Range is listed as 10m in open space; we got smooth playback even with a couple of walls in-between.

All’s fair in love and format wars; just look at VHS vs Betamax. Despite technical superiority, Betamax crashed and burned in the face of its VHS nemesis, and right now there’s a similar scuffle going on for your ears. This time it’s the superior-but-less-popular Kleer technology (as used by headphone-supremos Sennheiser and these DigiFi S2s) battling against common Bluetooth. The S2s have a 3.5mm-jacked transmitter that allows them to work with just about any portable player. They charge via USB and are capable of sending the most delightful CD-quality sound to your earholes.

Opera S5 – These earbud headphones use Kleer wireless technology and have a range of just under 10m, and 10 hours of battery life. You can skip through tracks and play and pause songs on your iPod using the control buttons ranged along the headphones and a small transmitter plugged into the bottom of your iPod.
Mac Format Magazine – January - Issue 216
By plugging the S5’s wireless transmitter into your iPod or iPhone, you can wirelessly beam your sounds to the earbud set using the 2.4GHz band. It has a range of about 32 feet, and up to four users can listen to the same sound stream.
The Digital Opera S5s are comfortable and offer a rich, balanced sound. It’s great to listen to your tunes without worrying about your iPod falling out of your pocket or the cables getting snagged and tangled. There was some interference around electrical equipment, but overall, they performed well.

4 Stars – “A great way to enjoy wireless music without compromising on sound quality.”

In the era of the iPod, headphones are big business. One product that caught SVI’s eye at the recent Manchester Sound & Vision show was WireFreeHiFi’s Digital Opera S2. Designed for use with Apple’s popular player this is a stylish behind-the-neck solution designed to do away with the pesky cabling linking headphones to player. To this end, it employs Kleer ultra low-power wireless technology, which allows the transmission of music from a transmitter (equipped with a standard iPod/iPod touch connector) to and ‘earset’ weighing just 22g.
Added functionality comes in the form of earbud-mounted volume and track control buttons, and the complete package, which also includes a mini USB cable for charging, is priced at around £70.
