TENHZ P4 Pro

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.

TENHZ previously Audbos is another newcomer brand which I bet you can already guess where they have risen from, and ready to slug it out with the Magaosi’s, Shozy’s and the Kinera’s with their overall similar build silhouettes and pricing schemes. The TENHZ debut wasn’t shy and right off released 2 offerings, the TENHZ K5 and the P4Pro which was sent to by Linsoul and DD Audio in exchange of an honest review,you can check it out or grab a pair from the Linsoul Amazon site and DD Audio AliExpress site.

The TENHZ P4 Pro is spec’d out with 4 Balanced Armature drivers, one being the 22955 Knowles BA drivers for the bass and 3 TENHZ-developed BA drivers for the midrange and the highs. TheP4 Pro housing is made from 3D printed smoked resin and has a pseudo-ciem silhouette which reminded me of how the Kinera H3 got popular with. It has a10Hz-40kHz Frequency Response, 26 Ohms Impedance and an 110dB Sensitivity.


The TENHZ P4 Pro came in a simple white cardboard box adorned with the P4 Pro outline, accessory set description and its FR chart. Pulling up another cardboard insert will immediately reveal a lovely brown leather case with a metallic slab of the TENHZ Audio brand, the inside of the case is black velvet and indeed had enough space to store the P4 Pro’s unlike some of the recent cases that came with some earphones that barely fits making storage of earphones a cumbersome. Underneath the case is the warranty card and manual and completely lifting up the cardboard insert will show the P4 Pro along with a set of red barrel black silicon ear tips (S, M, L)and another set of black foam ear tips(S, L) with the M being pre-installed on the P4 Pro.
The P4 Pro is made from 3D printed smoked resin which shows no weird jagged edges and the internal wiring can be discreetly observed which was done well. The BA drivers are clearly observable as well especially the 22955 Knowles BA drivers and there are also 3 tubes connecting the BA drivers directly to the nozzle covered by a metal mesh and has a lip making ear tip rolling welcome and the MMCX connection is also done well on the P4 Pro.
The stock cable comes out as silver which led me to assume that this could be another silver-plated copper due to the absent of actual cable specification from the manufacturer themselves. A touch of tension can be immediately noticed on the cable making them easy to fold and keep while still not retaining the folds. It uses a matte silver straight gold-plated 3.5mm plug with a clear strain relief, the aforementioned tension makes the strain relief somewhat a redundancy. The Y-split is a matte silver barrel type one and the MMCX housing is once again clear with a nice clear memory wire for over ear usage which did its job well. Microphonic noise is almost zero.

Being marketed as a completely transparent earphones made me wondered if it was for the overall look of the P4 Pro due to its smoked shells and the clear cables used or the sound itself, yeah whatever I think then. The P4 Pro came with foam ear tips although I chose to grab the Comply T500 for the realview, 16/44 FLAC files off the xDuoo X3ii and the Sony CAS-1 via an MSI GF62-8RE and Foobar2000 v1.4. The P4 Pro overall gave a flat signature with an emphasis on the upper frequencies which eventually gave the great synergy it had with the Comply foams ability to clean the upper end and amplify the lack luster low end.

I haven’t had the chance to try any Audbos products from where the TENHZ brand sprouted off although from the P4 Pro’s low end performance it would be safe to say they might have indeed had a hard time creating a smooth and clean low end. Anathema’s Distant Satellites provided a soft mid bass and a non-reverberating feel for the sub bass drops. Decay was a tad slow on the bass and speed suffered as well making the low end give out an overall lingering feel towards the lower midrange spectrum.

It is probably expected already for the Midrange to do some heavy lifting with how the low end performance of the P4 Pro extended towards the midrange territory. Michael Jackson’s Baby Be Mine showed how the lower midrange was able to compliment the low end bleed and render the midrange sound relaxing yet still sounding distinct and breathy with how the upper midrange was extended. Male and Female vocal and midrange oriented tracks did great on the P4 Pro, something to be retained in case TENHZ releases another IEM.

With my personal preference for the Bright signature, checking the high frequency performance is always a welcome experience. The TENHZ P4 Pro came to my party sporting an already weak low end while parading a great midrange. Daft Punk’s Beyond right off the bat highlighted the P4 Pro’s midrange strength and masking the low end although at the 0:43 mark, the sudden burst of the highs showed where the middle ground of the P4 Pro is, its highs. The intermittent delivery on the highs while still being detailed and delicate made the P4 Pro sounded flat overall and the then lackluster low end performance finally made it a welcome tuning.

Taking cue from the higher ups, I pulled out another Daft Punk track, this time the “Within”. The P4 Pro created its stage rather intimate than wide. Imaging was definite with a clear sense of its separation against the different instrumental and vocal deliveries. The intimacy created by the P4 Pro supplemented an already great midrange performer with its strong points being on the acoustic genre. I’ll be enjoying using this on some alone time, too bad alone time is rare for me.

The TENHZ P4 Pro relies heavily on its clean silhouette and great leather case with a flat signature implemented cleanly without being off tone nor off with its timbre delivery.The cable is just what you need really; stays in place, easy to store and the stellar absence of microphonic noise without giving up being looking good and not weird. The sound is easy to the ears and to like especially with its peers being either strongly implemented with a warm sound or a distinct bright performer,the P4 Pro will keep a welcome companion on the flat sound signature. Did I say that they sit comfortable on the ears too? With all those said, would I recommend the Tenhz P4 Pro? Read the realview again.
