The fight against low quality sound means another connection between your headphones and your source.

Who doesn't love a good dongle? Well, most people, actually - that's why some people were so vehemently opposed to Apple removing the headphone jack on the iPhone 7, to the extent that Apple co-founder Steve Wozniak argued against it and people have gone to drastic measures to put it back in.

Nevertheless, they do have some good uses. Getting better audio quality, for one.

That's where iFi's 'Ear Buddy' comes in. The way it works, according to the company, is by compensating for the loss of audio quality that occurs when you lower volume.

The example iFi gives is streaming music via Tidal, which has a 16-bit resolution. iFi claims that if you are listening at 60 percent of your device's volume you lose two bits of resolution - and therefore reduce sound quality.

With Ear Buddy, you can turn your device's digital audio volume right up - so you're not losing as much audio information - while the analogue dongle reduces the volume. Consequently you can listen to your headphones at a comfortable volume safe in the knowledge your sound quality is being preserved.

This isn't the first dongle in iFi's armoury - the company also has iPurifier2 for USB A, B, C and micro sockets.

The iFi Ear Buddy is available later this month, priced at £20. A lot for a dongle, perhaps, but might yet prove invaluable.
