Unboxing
Connectivity
Bluetooth
The Kiwi Ears Ardor’s BT 5.4 is capable of connecting to dual devices, as most are in this category. Latency while watching videos or movies on my PC is non-existent.
The dual connectivity allowed for quick switching between my phone and computer when called upon. Once a call was completed, the music started again without issue.
The initial pairing was straightforward, and it wasn’t until I realized that the Ardor would automatically connect to more than one device (after the initial connection) that I changed from connecting every time by purposely using the connect feature to simply connecting a single device.
USB-C
Paired this way, the USB-C to USB-C still uses the DSP of the Ardor. By using the onboard chip, the quality is ensured for accurate sound production. Immediately apparent was the disparity in volume between BT and the source, running in this manner.
After equalizing the volume to what I had with the BT level (by ear only), I found the sound through the USB-C to be quite extraordinary, mimicking a cabled closed-back headphone at this level.
The micro-details spoken about above became more evident (and not unexpected) and pronounced. The upper midrange push-up and forward were still there, but the added detail allowed for a more even, neutral signature. Bass became a bit more controlled as well.
Sound
The Ardor has a balanced and natural sound signature, following the renowned Harman tuning as a reference for optimal sound. Its bass is deep and powerful, but quickly limited in the midrange to avoid any bloat. The treble is tuned to align with the perceived human hearing curve, delivering a comfortable and precise listening experience.
The Kiwi Ears Ardor showcases a dominant bass presence that contributes to its rich and full-bodied sound signature. While there is some bleed into the lower midrange, this can also be seen as a skillful way to enhance the weight of the lower mids, effectively concealing what could be perceived as an overly pronounced upper bass area. This substantial low-end presence results in significant rumble when needed.

The upper midrange and treble notes provide a clear and detailed sound, maintaining a balance that is neither overly light nor excessively prolonged in attack or decay. The top end is characterized by a concise nature, offering a predominantly open sound signature that enhances spatiality.
The Ardor sound signature features a hint of airiness, achieved with a gentle push forward and upward in the upper midrange. This adds a touch of lightness to an otherwise smooth signature, while also enhancing the richness and warmth of the overall sound.
When ANC is fully activated, I notice that the bass can occasionally sound overly resonant and encroach upon the lower midrange, yet it delivers a solid presence during both the attack and decay phases. This results in a sound signature that is musically precise, albeit slightly heavy in terms of note weight.
The warmth contributes depth to the timbre, while also allowing room for the upper midrange and treble notes to create the lift and openness I perceive. This might appear counterintuitive, but often, that foundational bass clears the way for the reach of the upper midrange and treble. Naturally, in certain genres, the pronounced bass can appear to overshadow the signature, resulting in an even warmer sound.
The soundstage is more elevated than it is broad and profound, yet none of the three dimensions is deficient. The sound signature possesses a natural quality that enables note weight to contribute to the distribution across all three dimensions. This distribution also facilitates the blending of layers, obscuring a distinct separation of the instrumental components.
Punctuating treble notes contributes positively to dynamics, aiding in the separation of those layers. I have never found any of the sections to be deficient, yet I desire slightly improved micro-detail in the signature. The treble note is beneficial, but I believe a little more would be welcomed.
Macro-details remain quite good, especially with ANC on; however, the lack of micro-details can be somewhat mitigated by using the included cables or turning ANC off for a more open listening experience.
Sum-Up
If you choose to use the 3.5mm cable, the Kiwi Ears Ardor is a highly capable wireless headphone that can stand up to numerous competitors in the wired category. This speaks a lot about the tuning characteristics provided by the Ardor, making it one of the best wireless headphones I have tested within this price bracket.
