Over 10k? OK!

Penta‘s sound curve is very balanced around zero dB for the most of the graph, with a 10dB V curve just before the 10k mark and another just after it. This model responds in a band around the 18k with an “impossible” -10dB. The high frequencies in this model are superlative and come to your ear with an uncontaminnated crispiness. Made for music listening and for exigent musicians who don’t need high magnitude during performances.

Delighting freshness

  • Incredibly crisp high frequencies.
  • A balanced and flat sound with a kick on the high ranges.

Penta utilises the brand new electrostatic technology with a combined dual tweeter powered by a dedicated adapter (located inside the custom in-ear).
You should not consider the frequency response curve alone while evaluating this model, but also the quality of the final aesthetics in the high frequencies… even more when they are accompanied by an interesting balance of flatness from the bass to the medium-high band. The configuration of all the ET models must remain around the zero dB for most of the spectrum in order to achieve full perception of the Electrostatic Tweeter.

Incredible miniaturisation

Penta‘s technology is extremely precious and miniaturised: two electrostatic tweeters and a dedicated adaptor need to be fitted inside your ear, plus the other 3 standard drivers composing the sound engineering of this model that combines the considerable number of 18 electronic parts and almost one day of assembly including our tubeless outlet system.

Incredible cables

The standard cable provided with Penta is the famous Linum™ G2 BaX™, produced in Denmark by Estron. The characteristics of this cable in terms of reliability and duration are second only to its brother the Linum™ G2 Super BaX™. For more information about the Linum™ line please visit the respective product pages.

Porcelain feeling

Porcelain is definitely worth a try: you will be amazed by the extreme comfort of its smoothness conferred by the glaze, its total naturalness, its thermal adaptability and the absence of any allergene.
If you would never wear a plastic tooth, then you deserve porcelain in-ears!

A case of art

Our case is made of genuine calf leather, sapiently handcrafted by leather master craftsmen in Florence using a unique seamless technique. Our cases are naturally hygroscopic and will reduce the moisture that normally accumulates in your cIEMs without the use of chemicals. It’s composed of two nesting parts and comes with a cable holder and two magnets to attach it to your mic or music stand. Available in red or black color. See more
