The TRN V90S is a hybrid in-ear monitor (IEM) with a 1 dynamic driver (DD)+ 5 balanced armature (BA) configuration. The V90S is a direct successor to the TRN V90, which I previously reviewed on this blog:

Although it normally retails for around $50, the V90S will be available for $20 on TRN’s official AliExpress store for just $20. The V90S is available for purchase at the link below:

INTRODUCTION AND DISCLAIMER:

The Dunu Luna is an in-ear monitor (IEM) using a single pure beryllium diaphragm dynamic driver (DD) in each earpiece. The Luna retails for $1700. I had the opportunity to listen to the Luna through a review tour organized by Dunu. I am not being compensated for writing this review.

TANGIBLES:

The Dunu Luna is similar to Dunu’s DK series in its overall design silhouette, with a disc-shaped driver housing hanging below a cylindrical cable connector housing. The Luna opts for an understated all-metal build but does not look or feel cheap.

The Dunu Luna comes with a detachable MMCX cable with a modular, swappable termination. This is an elegant system, and I prefer it to a 2.5mm balanced cable with a 3.5mm single-ended adapter, which is more typical. The cable is also aesthetically appropriate for the Luna’s price point, which incredibly is not something I get to say very often. …

The V-Moda M-200 is an over-ear dynamic driver headphone that retails for around $350. I received the M-200 as part of the V-Moda Hardware Review Program. I had a few weeks with the M-200 before shipping it back to V-Moda. As compensation for taking part in the program, I received a discount code for use at V-Moda’s online storefront.

V-Moda was one of the first audiophile-adjacent headphone brands I owned as I started getting more interested in headphones and hi-fi as a teenager. Previous V-Moda headphones I’ve owned include the LP2 and the M-80. …

INTRODUCTION AND DISCLAIMER:

The Blon BL-05S is an in-ear monitor (IEM) with a 10mm carbon nanotube (CNT) diaphragm dynamic driver (DD). The release of the BL-05S closely follows that of the BL-05, which was widely regarded as a disappointing follow-up to the infamous BL-03. Thanks to the shipping delays caused by COVID-19, I did not receive my BL-05 review unit until many months after its release and elected to wait to review it alongside its successor. The BL-05S currently retails towards the lower end of the $40–50 price range. I received the BL-05S and the BL-05 directly from Blon, along with a Blon-compatible upgrade cable. …

The KZ ZAX is a hybrid in-ear monitor (IEM) with a 10mm PEK spring diaphragm dynamic driver (DD) and seven balanced armatures (BAs) on each side. KZ is one of the biggest names in ChiFi, and I thought highly of the ZSX “Terminator,” KZ’s last major wired hybrid IEM release. However, following the release of the ZSX, KZ’s previously frenetic release schedule slowed to trickle, and what new products they did announce fell mostly into the total wireless stereo (TWS) category. …

The CVJ CSA is a hybrid in-ear monitor (IEM) using one dual magnetic dynamic driver and one balanced armature on each side. CSA is a recent entrant to the Chi-Fi scene, and the CSA joins a crowded price bracket of 1+1 hybrids currently dominated by the KBEAR KB04. The CSA retails for $26.99 on Amazon at the time of this review. I purchased the CSA on Amazon and was reimbursed for my purchase by CSA prior to the arrival of the review unit, at a net cost to me of $.52.
