Oriveti Basic

Foreword: The Basic is Oriveti's new entry-level offering, a single dynamic IEM with sub-bass emphasis. This unit was loaned to me by my friend for a quick measure. While fooling around, I realised that the Basic was very sensitive with tip-rolling (spinfits vs wide-bore) which raised more questions on how much tip-rolling I have to do on my measurements.

Measurements on this post are done on the default "wide bore" tips. Measurements in the next post will be done on spinfits.

Wide-bore vs Spinfits



Left: Spinfits; Right: wide-bore
​

Analysis:

• The Basics are a sub-bass-focused IEM that strays away from the typical V-shaped sound that's prevalent in cheaper dynamic IEMs, being somewhat laid-back in the treble. Bass has a ton of punch and rumble whilst remaining surprisingly separated from the midrange considering its quantity.
• Changing to spinfits tames the 5k peak and some other small changes that linearises the FR curve up to 6k. I don't hear too much difference between tips (I only have one night with the Basics after all) but I do marginally prefer them with spinfits rather than the wide-bore tips.
• The impulse response appears to change (I assume, for the better) with spinfits. Admittedly I'm still in the learning process of reading impulse graphs so I'll need more data points to correlate what I'm hearing with what I'm seeing.
• CSD signatures barely (if at all) change with tips.
• Overall, with whatever tips you choose, the Basics are another solid recommendation as a cheap, bass-centric IEM that manages to keep its low end clean with its quantity.

 

Spin fits may be the worst tips you can use. They are like a reverse horn, reducing treble presence and extension, with their notched and bottlenecked bore.

 

I wouldn't say worst but the bore design does introduce some sound changes, whether beneficial or not being purely up to the user. I'll need to perform more experiments to see if this specific improvement in impulse is consistent with other IEMs.
