Intro

Neither AUDBOS nor TENHZ was known to me until now, but they already have a quite wide product range with any kind of dynamic & pure BA-In-Ears, as well as hybrids, among which there are technically some very interesting models. One of them is definitely the P4 Pro, which as the name suggests is an extended version of the P4, but which I can't compare.
I can already tell you here that the P4 Pro is a power in vocal-oriented music, as well as in spatial representation.

Handling

From the design point of view, we get a universal In-Ear in a custom look, as it can now be found in many IEMs. Synthetic resin in 3D printing and a compact design in spite of multi-drivers belong to the good manners in the Chi-Fi world (I leave out some Knowledge Zenith, CCA, or KB-EAR models), which is reflected in a very pleasant wearing comfort and good isolation.

Included are foam tips in three sizes and the same with silicone tips. In addition there is a very valuable hard leather case and a MMCX cable, which is silver coated, but qualitatively rather average.

Due to the precise 3D print, no sharp edges or unevenness are to be expected and the BA drivers, the crossover and the sound tubes can be easily recognized. Especially through the latter one notices that this is a product beyond the 100€ mark, as cheap Chi-Fi-IEMs most simply place their drivers somehow in the case without creating a clear separation. This means that the sound is then reflected unhindered in the case, which can sometimes backfire. Here the sound of the individual drivers is first bundled in the sound tube and transferred to the ear.

Sound

You like a mid-centered sound with a largely linear frequency response? Have fun with the TENHZ P4 Pro!

The P4 Pro is not an IEM that wants to score with its bass performance. The bass is clean and detailed, but not powerful enough for me, especially in the sub range, so that I find it a little harder to recommend the P4 without restrictions for some genres. The Knowles driver used can actually do more, but was apparently deliberately tamed to make the signature appear more neutral. But this causes me to lose some of the naturalness in the low frequencies, because bass drums don't sound full enough and even when the kick is present. However, it looks a bit different with electronically generated bass drums. The P4 Pro seems to cope better with this and you notice that some pressure is missing, but it can be arranged well, especially if you are used to the whole signature. All in all, the result is a solid, clean bass that emphasizes the midrange more and resolves well.

The heart of the P4 Pro is clearly the midrange. Vocal-heavy music and instrumental tracks are a real pleasure. The voices move a bit more into the foreground, which corresponds to my preferences, and in the upper midrange you should pay a little attention to the volume, since there are also small slips into the unpleasant, but this should not diminish the overall performance of the mids. The separation is very well done and the clarity and naturalness of the individual instruments and voices is remarkable. You really get lost in small details, which the P4 Pro brings to light very well due to its resolution and precision. Even though the bass doesn't play an important role in the signature, the mids don't look too thin, even in the lower range, but provide a healthy body, which makes the mids soft and warm overall, but in return also directly in the response and realistic. You shouldn't be deceived at first that the P4 Pro sounds a bit flat, this changes after a short familiarization.

The highs are bright and transparent. They spray some gloss in the upper area and have a decent extension. At the same time, they remain insensitive to sibilants due to the depression in the 6-8 kHz range. Likewise, no unpleasant peaks can be detected in the high-frequency range, which makes them pleasantly relaxed even for longer listening sessions. You have to be more careful with the mids. I appreciate this more than other pure BA-IEMs (e.g. BGVP DM6), which prefer the high frequency range almost too much. You can also uncover details without having to go to the pain threshold. This makes the difference. The P4 Pro therefore does not sound quite as airy and brilliant in the upper range, but shines with definition and texture.

Outro

If you listen to chartmusic with the P4 Pro, you could accuse it of emotionlessness and boredom! If someone describes the P4 Pro that way, I couldn't blame him either. It doesn't have the usual V- or W-signature, but rather tries to use a signature which emphasizes the midrange, for which the brain needs some time to adjust.
But if you feel at home in singer-songwriter, acoustics, jazz, or orchestral music, you'll quickly see what's special about the P4 Pro and learn to appreciate it, with its precise, warm and charming style, but also the one or other shrill slip in the upper mids.
Rock, EDM and pop music are not necessarily the strengths of the P4 Pro. The pressure and the power in the bass range are clearly missing and the emphasis of the mids could lead to fatigue. However, this music is not a No-Go either, just a pleasure with some limitations. Even those who prefer voices to be more on the same level as the rest of the mix probably won't be completely satisfied with the P4 Pro.

The P4 Pro is certainly not perfect, but I see something special in it and like to pick it up every now and then to avoid getting too used to a signature on the one hand, but on the other hand because I enjoy losing myself in details and appreciate the ingenious voice reproduction and separation, always with a squinting glance at the volume, which is enormous due to the low impedance.
