The Good Overall sound quality; simple operation; highly customisable; lossless audio-transmission method; optional headphone cable included.

The Bad Wireless reception drop-outs are problematic.

The Bottom Line The compact, comfortable Sleek Audio SA6s are stunning performers, particularly with acoustic, vocal and softer music. Wireless reception drop-outs when on the go are par for the course but still disappointing. When wired on the commute or wireless in the home and office, however, these are a great pair of earphones

Sleek Audio's SA6 earphones, which have been on sale for a while, now also come in a completely wireless edition -- and not using Bluetooth either, but rather the lossless Kleer technology.

They're on sale now from hifiheadphones.co.uk for around £250, and we've been giving them a test drive for a few weeks.

Design
The default set-up involves using the earphones wirelessly by hooking a lightweight receiver around the back of your neck. It's comfortable, lightweight and discrete, and suitable for running or the gym when worn correctly.

If the battery runs out, you can simply unclip the bits of the earphone that you put into your ear from the wireless receiver, plug them into the traditional headphone cable supplied, and use them as a normal pair of wired earphones. It's an extremely simple procedure, taking less than 5 seconds.

Compact and lightweight, the SA6s are a comfy pair of in-ear speakers. We had several continuous hours of usage without any 'canal fatigue', but whether or not this will be the case for you will depend on the size and shape of your ears, and the size of the tips you use.

Decent levels of sound isolation can be achieved using the tips provided, but we recommend investing in a pair of Comply's compatible tips for even greater comfort.

Features
In addition to their modular design, the SA6s use Kleer's wireless audio system. Kleer transmits audio data losslessly, so absolutely no audio quality is stripped out during the broadcast from transmitter to earphone, unlike with Bluetooth. This means, if you're listening to lossless audio on your portable player, you're not going to miss a single bit or byte.


The SA6s' wireless receiver is comfy, light and discrete

A single armature is used in each earphone, and we're told it's the same armature used by Klipsch in one of its high-end earphone products. They respond to frequencies between 20Hz and 20kHz, with an impedance of 50 Ohms and a sensitivity of 110dB/mW, and utilise a data rate of 2.4Mbps for transmitting the wireless audio.
