As the rest of the team keeps editing the great videos made at CES 2019, I’ve got to catch up on my homework again. Today we opened up a box of TENHZ P4 Pro in-ear earphones with four balanced armature drivers in each earpiece. Let’s take a closer look and a listen:
In The Box
The TENHZ P4 Pro in-ear earphones are packaged in a medium-sized box covered with photos and graphics. Inside you will find a molded foam tray containing the two 3D printed Resin body TENHZ P4 Pro earpieces and a set of small, medium, and large memory foam eartips. My test pair came in black and the foam eartips are also black. The P4 earpieces come with medium size silicone eartips pre-installed and a set of small and large silicone eartips are also in the molded tray. The silicone eartips are charcoal gray. Underneath that tray you will find a 1.2 m silver MMCX cable with a 3.5 mm jack. There is a dual language instruction manual which clearly explains how to change out the eartips for best fit, and how to properly attach the MMCX cable to your TENHZ P4 Pro earphones. Once you line up the left or right cable and earpiece, a firm push and the MMCX cable will be easily attached or removed from the P4 earpieces. Last, the nice folks at TENHZ included a classic look leather case which easily holds the TENHZ P4 Pro earphones, the MMCX cable, spare eartips and even some spare change. The TENHZ P4 Pro earphones each contain four balanced armature drivers including the 22955 Knowels drivers for bass/low-end, and 3 other drivers to cover the mid and high range frequencies. They are very comfortable to wear so take the time to get the correct size eartips installed properly. Let’s take a closer look, and a listen:
When evaluating any in-ear sound reproduction device like the TENHZ P4 Pro earphones, I will listen to many genres of music including but not limited to Rock, Classical, Jazz, Pop, House, and R n B. I even listened to some country music when testing the performance of these P4 earphones but please don’t tell my boss. I also put the TENHZ P4 Pro earphones on my test bench in the lab with some striking but absolutely unbelievable results. I plugged these devices into my PC, my Laptop, several iOs devices, a few Android devices, and my Amazon Fire HD to listen to music and watch videos on each platform. I accessed Mp3, WMA, and AVI files and utilized apps such as Amazon Prime Music, iHeartRadio, and others over the last two days of evaluation. The Stereo imaging was open and had a lot of clarity. The low-end was adequate, but one aspect of the TENHZ P4 Pro earphones became immediately noticeable: there is a harsh mid-range enhancement which I found to be overwhelming at times and distracting when listening to piano sonatas. I was really intrigued at what I was hearing and I had some idea what was happening so I took the time to look at the equalization curve when playing Rock music, Classical, and Pop. The TENHZ P4 Pro earphones evidenced a large enhancement of the mid range frequencies centering on 2kHz. I could see it on my meters and I could really hear it in my ears. When looking at Rock music, the “curve” was practically a 45 degree slope from low to high and I could hear that as distortion in my well-trained ears. When playing Dance/House music, or Pop music that enhancement wasn’t as harsh sounding, and I would attribute that to the normalization curve/compression used when mastering a recording in those genres. Finally, the TENHZ P4 Pro earphones can get really, really loud when compared to similar multi driver in ear solutions so always use proper caution and limit your exposure to extreme volume levels for long periods of time.
I have spent a lot of time in the last year evaluating and bench testing multi driver in ear headphones from many manufacturers. I will always explain what I hear, and why I believe it’s good or bad. The harsh mid-range boost in the TENHZ P4 Pro earphones was almost painful at times and not musical to me. My secretary, Ms T, however absolutely loved these earphones. This week we did an hour of in ear multi driver sound tests using her ears and earphones from 5 different manufacturers which I’ve done my 5 most recent multi driver bench tests. Everything I didn’t like about the TENHZ P4 Pro earphones was exactly what she liked the most and my favorite balanced EQ 6-driver earbuds she thought were just “Ok” . So if loud volumes, mid-range hot, and really great stereo imaging are what you are listening for in a multi driver in ear solution: the TENHZ P4 Pro In Ear Earphones are the pair for you. Now I know what to get Ms T for Secretary’s day. 7 out of ten, the TENHZ P4 Pro earphones are not for everybody. Remember to stay tuned to POCNETWORK.NET in the upcoming months: after a great week at CES 2019, we can’t wait to share with our readers the great devices which will be showing up later this year!!
