TinHiFi P2 ULTRA Evaluation
Abstract
The P2 ULTRA is a worthy flagship planar IEM for TinHiFi. It makes use of a Third-generation 12 mm, 0.02 mm ultra-thin, nanoscale-coated diaphragm planar magnetic driver with dual-layer N52 neodymium magnet arrays, which makes the sound very clear and the transient response very quick.
Execs
Good sub-bass presence with clear, detailed, and ethereal treble.
Spacious soundstage.
Small and light-weight gold-plated magnesium-alloy shells.
Cons
Low sensitivity makes it tougher to pair with reasonably powered sources.
The TinHiFi P2 ULTRA is the most recent within the firm’s planar-driver IEM collection and is at the moment priced at $599.
It was launched in late 2025, succeeding the earlier flagship planar, the P2 PLUS, and is positioned above the P2 within the product hierarchy.
I’ve been interested by TinHiFi for some time now, and I used to be fortunate to listen to the TinHiFi T6 and T7 in my earlier opinions.
What received me curious concerning the TinHiFi P2 ULTRA is its 12 mm Third-generation, ultra-thin diaphragm planar driver and its transient response velocity in comparison with the competitors.
To learn the way it performs and compares to the SIVGA Nightingale PRO and the Hidizs MP145 PRO, you may learn my full evaluation under.
Options
The TinHiFi P2 ULTRA has a couple of however high-quality options, probably the most notable of which is its Third-generation 12mm ultra-thin planar magnetic driver with a nanoscale-coated 0.02 mm diaphragm and dual-layer N52 neodymium magnet arrays.
The brand new planar driver is rated to ship 7 Hz–50 kHz frequency response, which is a really extensive bandwidth, to ship velvet-smooth ultra-high frequencies, lightning-fast transients, and earth-shaking but managed bass that solely desktop amplification exceeding 3 W can totally unleash, because the product web page stated.
The P2 ULTRA includes a distinctive backwave venting methodology known as the unique SPD™ Spiral Dynamic Respiration Panel, an open-breathing faceplate.
It’s mainly a Precision-machined spiral airflow channel on the rear, mixed with a high-density micro-mesh, that creates a form of “one-way acoustic valve” that vents back-pressure whereas successfully blocking exterior noise.
The P2 ULTRA additionally options efficient ear canal strain reduction. This prevents strain from build up within the ear canal whereas listening, which might trigger fatigue, ear ache, headache, and nausea.
The P2 ULTRA has an impedance of 32Ω and a sensitivity of 98 dB/mW @1kHz, so I can inform straight away this IEM won’t be tremendous delicate.
Design
One factor I seen straight away is that the Spiral Dynamic Respiration Panel within the P2 Extremely’s faceplate feels just like the floor of a nail file. I attempted my nails on it, and it really works. I’m not saying it’s ugly, but it surely simply appears to be like unusual to me, being within the faceplate of an IEM.
Nevertheless, the ergonomically formed, small, light-weight, and 24K gold-plated magnesium alloy shell appears to be like lovely each within the arms and on the ear. It appears like I’m having physique equipment when utilizing the P2 ULTRA, because the shiny gold shells add bling to the listener.
I’m joyful to see the P2 ULTRA makes use of QDC-style 2-pin connectors, that are simpler to like than the MMCX connectors used of their flagship single-DD IEM, the T7.
The P2 ULTRA may be very light-weight at 5 grams per shell, which is under common among the many IEMs I’ve examined. It has a 5.8 mm diameter nozzle, which is common and throughout the supreme limits of 5.6 mm to six mm in my view.
Inventory Cable
The P2 ULTRA comes with a thick cable that includes a Japanese Mogami coaxial core and an 8-core 5N single-crystal copper with a thick silver-plated hybrid braid.
Throughout use, the cable feels a bit of stiff and never very compliant. Which I view as a optimistic, because it means the wires are stuffed with actual metallic conductors.
Not like lesser-quality cable of comparable thickness, which is smooth and compliant however has plastic fillers alongside the copper braiding inside. I realized about this throughout my DIY IEM cable-making days years in the past.
My evaluation unit comes with a modular cable with 3.5 mm and 4.4 mm plugs and a Sort-C Single-Ended plug. For an additional $30 or so at checkout on the TinHiFi web site, a separate USB-C cable, known as the TC01, with or with out an Apple Lightning adapter, can be included.
I attempted the included USB-C plug, and it sounds good, heat with an prolonged treble, however with much less decision than my sources. Its most quantity is low; it barely reaches my regular listening degree, and it doesn’t go as loud because the ANC wi-fi earbuds I’ve reviewed.
Consolation & Isolation
Because of the ergonomic form of the small and light-weight magnesium alloy shells, the P2 ULTRA may be very comfy to put on. I did my strolling train, a protracted listening session, and rest in mattress utilizing the P2 ULTRA, and it pale simply from my consciousness, letting me benefit from the music unbothered.
Nevertheless, I discover the liquid silicone ear suggestions take getting used to and must be oiled to be efficient at air-sealing, as they have an inclination to catch on the outer a part of the ear canal and received’t slide in simply, making it troublesome to get a correct seal.
As soon as it’s used a number of instances and the floor is coated with pores and skin out, it slides in and seals simply.
Noise isolation is common, which I take into account a optimistic, as I don’t need to be utterly deaf to the skin world whereas carrying the P2 ULTRA throughout a public strolling train.
Packaging & Equipment
I’ve a very good first impression of the P2 ULTRA’s large black field, measuring 202 x 193 x 104 mm, with an outer sleeve. The principle field opens from the highest to disclose the P2 ULTRA, with a drawer on the backside entrance housing the equipment.
The packaging features a pair of P2 ULTRA IEMs, a modular cable, a 3.5mm plug, a 4.4mm plug, a Sort-C adapter, 3 pairs of reminiscence foam ear suggestions, 3 pairs of Liquid Silicone ear suggestions, an ear tip case, a leather-based storage case, a cleansing brush, a pair of plastic tweezers, a pair of additional metallic filters, a consumer handbook and guarantee card, and a cable cinch.
Sound Impressions
I spent about 24 hours of the burn-in interval by letting it play with a DAP repeatedly at regular quantity whereas checking in now and again.
I seen a delicate enchancment within the background’s cleanliness, however in hindsight, I estimate that the P2 ULTRA solely wants about one hour of burn-in, as I by no means seen it enhance after that time.
For the sources, I used my iBasso DC-Elite and MUSE HiFi M6 Double DAC amplifiers with my Android telephone, and the FiiO M15S DAP, utilizing YouTube Music, UAPP, or PowerAmp music participant Apps. No EQ or any sound enhancement packages had been used.
I used the inventory liquid silicone ear suggestions and the inventory cable with the 4.4 mm plug.
Measurement
My measurements of the P2 ULTRA reveal a well-balanced channel set, with solely a minor, inaudible imbalance in some frequencies.
The height at 8 kHz is partly because of the measuring software’s resonance and isn’t as pronounced because it seems throughout listening; the general rise within the higher treble may be very noticeable, although.
Abstract
The very first thing I seen with the P2 ULTRA is the crispness and airiness of the treble. It’s very detailed, nuanced, delicate, pure, and shimmery, with out sounding overly shiny, harsh, or fatiguing.
The P2 ULTRA has an audiophile-style, analytical, U-shaped sound signature with good subbass presence and extension, a recessed midrange and treble, and a boosted higher treble.
I used to be cautious, earlier than listening, that the bass can be gentle and skinny because of the ultra-light shifting mass of the planar drivers. I used to be very stunned that the bass is prolonged, weighty, and thick, as if it had been coming from a dynamic driver.
Midrange has a lush, relaxed sound with loads of element and correct be aware weight. The higher midrange and decrease treble are recessed, which makes the general sound presence laid-back.
This sort of tuning ensures a really low fatigue issue, as most individuals are delicate on this area of the audio spectrum. Nevertheless, this additionally makes the sound too laid-back for some individuals, together with me.
I like the way in which the higher treble is boosted, because it sounds pristine and ethereal, with loads of microdetails with out sounding unnatural.
Moreover, the precise perceived decision may be very excessive, and the transient response may be very quick.
Coloration
Except for the U-shaped sound signature of the P2 ULTRA, I discover the higher midrange is recessed, which might make for a non-fatiguing sound even at loud quantity. Nevertheless, it sacrifices the vocal presence and makes the snare drums extra subdued.
And although I like the way in which the higher treble sounds, pure and non-fatiguing, I discover it clearly boosted.
Nonetheless, the P2 ULTRA nonetheless sounds pure, avoiding undesirable coloration like skinny, dry bass, peaky higher midrange, and dry, harsh treble that I affiliate with older-generation planar IEMs I heard years in the past.
Soundstage
The P2 ULTRA’s soundstage is undeniably spacious, with the devices and vocals emanating from a distance. When enjoying some songs at loud volumes, it appears like I’m in the midst of a big live performance corridor.
The soundscape is extensive, deep, and excessive, with an immersive surround-sound sensation that I discover very satisfying.
Though the photographs might come from the acute left or proper facet, with good panning efficiency and a secure middle picture of the primary vocalist. They are usually located at a distance, and few holograms are projected to drift within the middle entrance space.
There may be good side-to-side instrument separation and an affordable diploma of definition, however the front-to-back layering and the picture holography aren’t pretty much as good as a few of the finest I’ve heard.
The P2 ULTRA appears to sacrifice a good quantity of imaging efficiency for excellent staging, which is, in my view, a greater compromise in comparison with when it’s the opposite approach round.
Dynamics
The P2 ULTRA has a energetic, energetic sound, particularly within the bass and upper-treble areas. I by no means had a track that made the sound anemic, even at pretty low quantity ranges.
Nevertheless, I seen that it has lower-than-average sensitivity, which requires me to extend the quantity setting considerably to close most on my iBasso DC-Elite to match the conventional loudness of the opposite IEMs for comparability on this evaluation.
