Still listening to your music with the free earphones that came with your smartphone? Well, stop. They are almost certainly ruining your listening experience, and while you may not know it now, a decent pair of earphones makes a massive difference to the quality of your music.

Upgrade to the AviiQ Concert Series earphones and you’ll enjoy deeper bass, crisper vocals, and a much-improved sound experience overall. You’ll also get noise isolation and tangle-free cables, and for a limited time, they’re just $19.99 — that’s 42 percent off — thanks to Cult of Android Deals.

The AviiQ Concert Series will dramatically improve your music experience with its finely tuned 9.2mm drivers that give you music the way it was meant to be. Whether you’re listening to heavy rock, smooth jazz, or soothing chill-out tunes, it all sounds better with AviiQ earphones.

They also drown out the sounds of the city streets with up to 20db noise isolation, and that have a built-in microphone and remote that allows you to take calls on your smartphone. They’re durable and resistant, and their tangle-free cable ensures you never have to deal with messy wires again.

The AviiQ Concert Series uses a standard 3.5mm headphone jack, and comes boxed with six pairs of earbuds and a dual-prong flight adapter. If you order within the next 9 days, you can get them for just $19.99 — down from $35 — thanks to Cult of Android Deals. Just click the button below.
