Technology

Our technologies.

Every detail, from the fit to the crossover, designed in our lab.

New

Hybrid Fit™

A custom shell from your impressions, with a soft silicone tip at the end. The stability of custom with the comfort of universal.

Learn more

Immersive Mode™

A switch for the bass. Off, the lows blend gently into the mix. On, they turn fuller and more physical, without any mud. Your choice.

Flex Fit Pro™

A flexible 3D resin in the part that goes into the ear canal. Within minutes it takes on your ear's temperature and turns softer and more comfortable than a conventional acrylic mould.

Perfect Fit™

We scan your impressions, design every shell digitally and 3D-print it, for the most comfortable fit.

Complex™

A crossover design that gets the most out of every driver: balanced sound, coherent phase, low distortion and matched left and right.

Worth the upgrade! Custom fit and the sound is amazing, truly next level upgrade from regular in ears. Build quality is nice. Expect some time to ship and get them back but happy to order from a European country.

Great quality ears, great reactivity from Apostolos and great production time, in addition, living in a distant country, the possibility to work from 3D scans is really convenient and the ears fit perfectly in the end, great isolation ! to resume in a simple word : Great :) i highly recommend Soundz in ear (Dune model user)

I desperately needed customized ear plugs for sleep and received a tip about Soundz. From the first contact with their international sales manager Apostolos till receiving the ear plugs by post, the service was impeccable. I am absolutely amazed at the quality of their ear plugs for sleep. They are comfortable to wear, non-itching, almost non-sweating and the environmental sounds are cancelled out to a great extent. I can finally sleep without being disturbed by loud noise! I am very grateful.

Ότι καλύτερο υπάρχει σε Custom IEM!!! Τα προτείνω ανεπιφύλακτα!!! (Flame - 8 drivers per side) Τέλειος ήχος με λεπτομέρεια και απόκριση όλου του φάσματος των συχνοτήτων. Τρομερή άνεση όταν τα φοράς. Είναι σαν να μην φοράς ακουστικά. Είναι ιδανικά για πολύωρα live. Επίσης ένα μεγάλο μπράβο στην ομάδα της Soundz για την βοήθεια, την υποστήριξη και το service που παρέχουν, οπότε αυτό χρειαστεί. Και το σημαντικότερο, είναι ένα 100% Ελληνικό προϊόν!!!

Άψογη εξυπηρέτηση και ενημέρωση αν χρειαστεί, για το προϊόν Soundz Uni Music που πήρα, πραγματικά εντυπωσιακό, στην αρχή νόμιζα πως δεν δουλεύει γιατί ακούς ολόιδια αλλά πιο χαμηλά. Σε μεγάλες εντάσεις συναυλίας απλά σου κόβει το φύσημα του χάους και στο καθαρίζει, ίσως κάνω upgrade τις Custom κάποια στιγμή για απόλυτη προστασία.

Πολύ ευχαριστημένος από την αγορά ωτασπίδων ύπνου ... Καμιά σχέση με αυτές των φαρμακείων... Ακριβές αλλά αξίζουν... Και συνήθως ότι πληρώνεις, παίρνεις...
