Before starting this review, I would like to share technical aspects and package details.
Also, I am so thankful to Oliver from Inear Audio for giving me this opportunity.

Package, Design & Isolation;
PP8 (Prophile 8) package content is quite good. There are many different tips like Spinfit and Comply, also Pelican case, cleaning wipes, sound filters and adapters. I satisfied with the contents of the box. The PP8 shell design is like a ciem which is amazing for the fit and isolation. My PP8 is normal (not small shell version) and can be used by many users without problems.
PP8 design is just wonderful. Outer matt material is like inspired by the radar-untreated warplane. I like matt colour more than the glossy black one. PP8 has 2 audio switches on the inside and it is easy to change the sound character here. The switch placement in the shell is pretty good choice for both ergonomics and durability. With these switches, it is possible to make reference to the sound character or increase of 3db in the bass.
PP8 is the best universal earphone I have ever used in terms of fit and isolation. InEar engineers decided on this design by using many earplugs demo. I did not have any pain even if I have been using it for a long time. My only criticism is about the stock cable. PP8 is TOTL earphone and this cable does not match with PP8, but when I talked to Oliver from Inear Audio, he stated that Prophile 8 is produced mostly for stage performances so the cable preference is thin and ergonomic.
As isolation, PP8 has the best isolation I have ever used. The design of the shells plays a huge role. The PP8 almost covers every part of the outer ear. As I have already stated in my previous reviews, isolation with comply foam tips is much better than silicon tips, but I have achieved a very successful isolation with silicon tips too.
The sound is, in fact, technically brilliant. When the reference switch is turned on, the sound character is much flatter and it turns to a reference character. In this mode, the PP8 brings more technicality to the foreground and offers a studio-like sound character. The resolution and the detail levels are quite high. In fact, I can easily say that I heard that kind of high level of detail and resolution in only at 2-3 IEMs. The reference mode is quite successful at recording in the studio -not only for the studio, but also for classical music, jazz and easy listening. I recommend to switch the Bass position on for those who want a more authoritative bass presentation. The bass becomes more dominant so the body and the presentation become more musical. I love the switches’ position on because of the bass presentation. It does not lose any detail and resolution, but it turns into a musical and dynamic earphone. The details are very easy to capture and the distance between the instruments is quite high on a wide soundstage.
When I first heard the top frequencies while the reference switch is turned on, it sounds a little dull and dry. I think that the reason is the analytic and reference character of the earphone and I felt that I could not love it very much. But after listening it for 2-3 hours, both my ears and brain get used to it. After detailed listening, I noticed that the trebles actually played quite a bit from the right tone, and they played a lot more referenced than any other earphones I have. The trebles are quite distinct and have very high resolution in overall. It plays from a large area. The overall presentation is stress free and it extends as long as necessary and It never loses control. I have heard lots of clear and detailed earphones, but the PP8 is different than the others because it has right tone on the top frequencies and it is truly transparent. There is no roll-off at the trebles, but it extends as much as possible. I have never heard of sibilance even though while listening it with all the resources in my hand. The treble is extremely fast. Taking advantage of being quick, there is no mixing and losing control even in the complex passages. The trebles are airy and have a spacious presentation even though the amount is too much. At switch on position (fun character), the trebles are distinct, but slightly softer and more musical, as in the reference setting.
The middle frequencies start to become flatter, they accompany the bass and treble in parallel. I listened it again while it is switched on. Middle frequencies are clean and crystal clear. You can hear all the instruments and vocals, both natural and without grain. It may be the most transparent earphone I have ever heard. The instruments are quite realistic and you can notice how it is close to natural tone. The vocals are relatively close, so the instruments feel like coming more farther than they are. Instrument vocal distinction is quite high, but for those who like bold- intense mid-range presentations, the mids may be little bit thin. Of course, this situation creates airiness to the soundstage. Mid instrument separation is still quite high. All kind of instruments can be heard without touching each other. Positioning in the soundstage is very easy to listen. In this sense, I can say that the PP8 can handle all genres.
The lower frequency quantity is not so much, so the PP8 will not be a good option if you want a powerful bass. The PP8 reference does not go to deep lower frequencies. It would not be correct to perceive this as a disadvantage because the earphone has a reference sound character naturally. This is not a bass-head earphone. However, if I need to criticize, the bass is deficient towards low mids which causes body weakness in some tracks. Of course, you can increase this with the bass switch. When it is switched on, there is a noticeable bass boost. The bass is increasing in quantity and the overall presentation is getting bolder.
I prefer the switches on, I liked it more. Bass do not lose control in the fast-paced parts. When the switch is turned on, the bass quantity and volume increase, and again, it becomes more dominant in overall presentation. In this sense, I loved the quantity and the resolution both. You can even hear the slightest movement in the drum.
Soundstage is the most realistic and convincing one I have heard yet. It is quite wide and deep. The imaging is extremely precise. The instruments can be easily placed in a wide area and positioned correctly in the soundstage. Also, PP8 has a very good 3D imaging. The fact that the stage`s width creates a spacious and airy presentation. Another advantage of the spacious and airy soundstage is a stress-free presentation. The background of the PP8 is quite dark and clear.
Awesome isolation and sound quality! This is the best explanation for Prophile-8. Isolation of the PP8 is absolutely fantastic. After using different earphone brands, other earphones make you feel uncomfortable and primitive. InEar’s shell design is simply gorgeous. Also, the build quality is solid and sturdy.
Overall, I am highly satisfied with Prophile-8. It has a bit bass light, but still it has a good amount of bass. This is definitely endgame earphone for who are looking for a reference and detailed sound signature.
