There is a quiet disappointment in tapping through a phone's EQ presets and hearing… nothing. A lot of music apps show the control because people expect it, but the effect is faint or absent. An equalizer is only worth having if you can hear it work.
What "10-band graphic EQ" actually means
A graphic equalizer splits the audible spectrum into bands — ten of them here, from deep bass up to high treble — and lets each be boosted or cut. Lift the low bands and a track gains weight; lift the highs and cymbals and vocals get air; dip the middle and you get that scooped, modern sound. Ten bands is enough to genuinely shape a song rather than just nudge "bass" and "treble."
It is applied live, and you can hear it
RetroDeck runs its playback through a real equalizer, so switching presets makes an audible difference immediately — no restart, no "apply" step. Pick a preset on a playing track and the sound changes under your ear. It is a true audio effect on the app's playback, not a cosmetic label.
A full set of classics ships in the box — Bass Booster, Bass Reducer, Treble Booster, Rock, Pop, Jazz, Classical, Dance, and Spoken Word among them, plus a flat setting for when you want the track exactly as recorded.
Why it matters on a player like this
If you are going to listen to the music you actually own, on good headphones, you want some control over the sound. A bright recording can be tamed; a thin one can be filled out; spoken-word and podcasts can be made clearer. The EQ turns a faithful player into one you can tune to your ears and your gear — and like everything else in RetroDeck, it is part of the single purchase, not an add-on.
Tune it to your ears.

Frequently asked questions
Does the iPhone have a 10-band equalizer?
The built-in Music app only offers fixed EQ presets with no manual control. For a true 10-band graphic equalizer, you need a dedicated app — RetroDeck includes one, applied live to the music it plays.
Is RetroDeck's equalizer actually audible?
Yes. RetroDeck runs its playback through a real 10-band equalizer, so changing a preset audibly changes the sound. It is a genuine audio effect, not a label that does nothing.
What EQ presets does RetroDeck include?
Classics from Bass Booster and Bass Reducer to Treble Booster, Rock, Pop, Jazz, Classical, Dance, and Spoken Word — plus a flat setting. Changes apply instantly, with no restart.
