Letshuoer Cadenza 12 Vs 64 Audio U12t Comparison Review

I recently checked out the Cadenza 12 from Letshuoer, and it was highly enjoyable. With a brand like Letshouer, sometimes stacking it up to a big name like 64 Audio can offer some insight into its ability. There is some discussion already on how the $2,299 Cadenza fares against the $1999 U12t, so let’s see what their strengths and weaknesses are when put up against each other.

Look & Feel

64 Audio doesn’t change much with its designs, but they found a style that works and they stuck to it. I’m quite fond of their builds, and the U12t is no different. The U12t has a solid aluminum shell structure and a shape that sits naturally in your ear without causing any problems. With the Cadenza, Letshuoer goes a bit more flashy. Its outer casing is made from titanium, giving the Cadenza a harder shell. Its reflective silver finish is also very striking. You may think this type of build would hinder its comfort, but the Cadenza holds up with a naturally comfortable fit as well.


The Cadenza and U12t have similar driver configurations. It uses a series of 12 drivers with a six-way crossover and five acoustic bores. This includes a hybrid of Knowles and Sonion balanced armatures, as well as a 10mm dynamic driver. The U12t also sports twelve drivers but incorporates their tia and LID systems.


When you’re up in this range, you expect the best, and both IEMs deliver. Although they go about their soundstage in different ways, their ability feels top tier. Especially the U12t, which is just so extravagant with its movement and precision. With the Cadenza, the soundstage is tighter, but it shows articulate sound elements by using separation and layering to great effect. Both IEMs show a lot of depth in their imaging, but the Cadenza actually feels like it has more of a breath to it. The U12t is fantastic for accuracy and dimension, but the Cadenza shows some impressive liveliness in its imaging, appearing more like a bubble. However, there is some considerable height missing, and the U12t supplies that in droves.

Low End

Depending on what you’re looking for, the U12t and Cadenza can give you exactly what you need in the bass. If you’re seeking a more natural response that also doesn’t hold out on texture, then the U12t is nearly perfect. The Cadenza also has a considerable bass timbre, but on the surface, it has more personality. It comes at you with a more bodied tone, displaying thickness and impact more consistently. You might get more fun out of the Cadenza than the U12t, but the U12t is better for detail and resolution.


If you’re more into midrange detail, then the U12t is definitely going to offer the goods. There’s a purity to the frequencies, and it makes each instrument pop with an incredible velocity. Each note has a distinguished identity to it, which gives performances an unrivaled energy. The Cadenza is smoother in comparison but still operates with a natural timbre. It doesn’t have quite the transparency, and the notes don’t come down as hard. However, the response is still very fulfilling and offers even more roominess to the sound signature.


Both the U12t and Cadenza have an emphasized treble, showing great extension and detail. When listening to the Cadenza, I feel like there are more centralized frequency contents, and it might be a bit overwhelming. The U12t has a lot more room to move around in its high-end, and it gives the frequencies an opportunity to be more digestible. With the Cadenza, some of the tone can get pretty hot, but not in a way to sounds harsh.


Letshuoer and 64 Audio do the very best they can with their 12-driver IEMs. It’s interesting to hear the different results they come up with, as they’re two very different sound profiles. When it comes down to it, the U12t is still unlike any other pair of IEMs, with its incredible accuracy and overwhelming detail. The Cadenza holds up nicely though and provides its own character that offers a different flavor for this price range.
