The Sound:

Please note that this review is written after a burn-in process of approx. 80 hours. I have use the double flange eartips that where included to the package.

The Periodic Audio Ti is an In-Ear Monitor with a V shaped sound signature, which has pretty forward and deep bass, recessed and slightly veiled midrange and a bit bright treble presentation. All this characteristics making the Periodic Audio Ti to an warm and fun focused In-Ear Monitor.



The bass is one of the main attractions of the Periodic Audio Ti. The bass quantity and punch will satisfy most bass-head’s, while the quantity can be a bit too much for those who prefer a more balanced bass presentation. The Ti sounds very pleasant end exiting with genres like Rap, hip-hop, pop, edm or trance.

The sub-bass of the Ti has good extensions and are going to a pretty low register and you can both hear and feel the power of the bass, which is produced by the single dynamic Titanium diaphragm driver.

The midbass of the Periodic Audio Ti have slightly less emphasis than those of the subbass, but it’s covering a quite large area in the sound spectrum. It is pronounced and is hitting pretty powerful, while I have noticed that there is a small midbass hump and that it can sometimes bleed in to the midrange, especially in bass heavy songs.

The bass is punchy and hits hard and shows a warm texture. One of the positive points of the bass that is produced by the Periodic Audio Ti is that it is punchy but not very hard in its character.

When it comes to the bass speed, I can say that the Periodic Audio Ti has an average speed which is pretty enough for example genres like pop, rock etc. but is not very ideal for faster genres like metal music.




The midrange of the Periodic Audio Ti is due to the V shaped sound signature positioned behind the treble and bass, which means a noticeable recessing of the midrange.

The midrange is sounds a bit veiled and tick in tonality.



The Periodic Audio Ti has a quite soft, sweet and musical vocal presentation. Male vocals are sounding quite successful and musical due to the lower midrange tuning, which makes the listening to vocals such as Dave Gahan, Eric Clapton or Jeff Buckley to a joy.

Female vocals are sounding soft and warmish without any remarkable harshness or sibilance.

Female vocals are sounding a bit veiled / muffled because there is not enough space for a clean presentation, while the Periodic Audio Ti is quite successful and entertaining with vocals in genres like EDM or Trance such as Emma Hewitt.



The Periodic Audio Ti has a soft, musical and slightly veiled instrument presentation with pretty high fun factor. There is no harshness and no ear piercing brightness while listening to instruments such as flutes or violins. Guitars have a lush, a bit bassy and fairly thick tonality.

The pianos are quite soft, slightly warm and lightly bright in its presentation, while the notes are not very pronounced and detailed.

The violins have a soft and warm presentation and there is no unnecessary harshness, while it sounds a bit too dark and hot while listening to this instrument. The Periodic Audio Ti is missing some extension and detail while presenting instruments such as violins or pianos.


Upper Midrange:

The upper midrange structure of the Periodic Audio Ti is not very upfront and shows a soft presentation. The upper mid emphasis is not high, it is a bit thick and warm sounding. There is a slightly lack of airiness and extension, which makes the presentation of instruments such as pianos, flutes or violins a bit veiled and muffled.

The general presentation of the Periodic Audio Ti is not very airy and transparent.



The treble area of the Periodic Audio Ti is a bit polished to give refreshment to the overall presentation and sounds in general thinner compared to the bass and the mids. The treble range is positioned slightly behind the bass and is missing a bit of extension and air.

Metal and Rock listeners will may find it a bit hard to define instruments such as cymbals, while EDM listeners will may find it a bit too dark; as a result the treble performance of the Periodic Audio Ti slightly behind its price level.



The Periodic Audio Ti is a warm sounding In-Ear Monitor with an average soundstage expansion. The soundstage depth is slightly higher than the width, while the separation of instruments is on an acceptable compared to other IEM’s in this price level.
