In conclusion, these PSB earbuds feature a unique dual driver, a planar magnetic transducer paired with a dynamic transducer, as far as I know, a first for a true-wireless component. This combination results in a sweet and natural sound. At USD 199, they are priced well. If you’re into the tech that comes with earbuds at that price, these PSB earbuds may not be for you. However, if you’re looking for a more analog sound, comfortable, and natural-sounding earbuds that can be used anywhere, even in the gym, with buttons instead of those dreadful touch sensors, then these PSB earbuds are your best bet.

There is roughly a 5 dB drop from 20Hz to 200Hz with less presence from the sub-bass right up to lower mids. Thereafter, or from around 1k there is roughly 2 dB less elevation than the default tuning up to 7k so vocal imaging drops back a little creating a slightly more relaxed midrange presentation.

Switch 3 also has more treble energy than the rest of the switch options and it’s the option where you can best hear the EST driver’s presence on higher-pitching instrumental timbre.

The packaging includes a finely designed plastic ear tips container featuring Noble’s logo, containing both wide-bore single-flange tips and more stubby double-flange tips, much like what was provided with the Mystique. Additionally, a nicely made velvet pouch is provided to protect the Alcantara charging case from drops. As for charging, you get a USB-A to USB-C cable, and due to the slightly recessed USB-C port on the case, Noble includes a C-female to C-male adapter, allowing you to charge the case with standard USB-C cables, which typically have a shorter connector length.

The mid-range of the Terra shines with clarity and vibrancy, bringing instruments to life with dynamic energy. Its transient response aligns with the bass’s excellence, while the timbre strikes a great balance, offering a natural sound without leaning too warm or thick. The mids are well-bodied but stay controlled, maintaining a balanced and refined presentation.

For its price, the mid-range stands out with top-tier definition, transparency, and resolution. The positioning feels precise, and the natural timbre adds to the overall sense of realism. The Terra offers a detailed, engaging, and non-fatiguing mid-range that excels without being too forward or forced.

The PMG Audio Apx SE immediately stands out with its thoughtfully crafted design, blending sleek lines and high-end materials to deliver both visual and tactile appeal. Its minimalist aesthetic, paired with premium finishing, results in a product that effortlessly complements any setting—whether it’s placed on a desk, displayed on a shelf, or used while travelling. The Apx SE radiates a sense of sophistication and luxury.

I am also happy, that 64 Audio included a small lip on the nozzle of the Aspire 4. This is another step forward from their previous universal IEMs, which did not feature it. The lip makes sure, that ear-tips stay on the nozzle when you take the IEMs out of your ears. There have been multiple accounts of that happening to me in the past. And a stuck ear-tip in the canal is no fun.

Overall, the Aspire 4’s build quality leaves me little to nothing to complain about. The ABS shells might not be the most premium choice, but they still look and feel good. Plus, they are a way to cut down costs, which eventually also land at the consumer’s end. And I think all of us agree that paying less is always nice.

These earbuds deliver superior performance in true-wireless sound and technology. I expect the big companies to use words like “Lossless” when it comes to wireless headphones, and that might be a bit of a stretch because of what I described above. The sound of these earbuds was not night and day compared to others, but it had significantly better dynamics in their tuning for my taste, the best frequency is the low-mids and bass response, and because of this they can be enjoyed with many genres. For comparison, the more expensive Sony WF-XM5 buds sound less alive and with a more constricted soundstage. The Sennheiser Momentum 4 (USD 269.95) is the heavyweight of this class, a great and versatile component. Highly recommended.

The Binary Dynaquattro features CNC-milled & anodized steampunk faceplates made of aluminum along with a semi-transparent 3D-printed shell. The faceplate design cleverly represents the 3DD+1PR system by matching the wheel sizes to the dynamic driver dimensions. I love these kinds of design details; we all need a touch of creativity once in a while in this crowded market. In addition, the center of the bottom wheel, which appears as part of the faceplate design is actually a hole that serves as a vent for the dynamic drivers, another aesthetically pleasing detail!
