Ultrasone HFI 780 Recensie | 93 Gegevens vergelijking

The Ultrasone HFI-780 closed-back headphones are praised for their immersive S-Logic technology, delivering a wide soundstage with deep, punchy bass and excellent passive noise isolation suitable for gaming and music. These efficient, low-impedance headphones offer high-energy, detailed sound that is highly engaging without requiring an amplifier. However, the HFI-780 is widely criticized for severe comfort issues, including high clamp force and a painful, unpadded headband, causing fatigue within an hour of use. Furthermore, users report a divisive, artificial metallic sheen in the mids and piercing treble that can become fatiguing, along with an inconveniently long stock cable.

This Head-Fi review compares the Ultrasone HFI-780 and DJ1 Pro, noting the HFI-780 offers a "colored," fun sound with punchy bass suitable for fast music and portable devices. However, it features a narrower soundstage and requires a tedious burn-in process. Conversely, the DJ1 Pro functions as a, precise, reference-oriented headphone with a wider soundstage, greater depth, and analytical transparency ideal for monitoring. Its cons include an unforgiving nature that highlights low-quality recordings, lacking the warm, musical "flavor" of the HFI-780.

The DIY Audio Heaven thread evaluates the stock Ultrasone HFI-780 as a visually attractive but sonically flawed headphone that struggles to deliver a hi-fi experience out of the box. The primary pros highlighted by the reviewers are its appealing real-life aesthetic, strong structural sturdiness, decent passive isolation, and deep sub-bass extension. However, these positives are heavily overshadowed by notable cons, including a severe driver channel imbalance, recessed and "thin" mids, and a highly intrusive, piercing treble peak that causes rapid listening fatigue. Furthermore, the stock plastic earpads are criticized for being stiff and uncomfortable, which often prevents a proper acoustic seal and causes the bass to disappear entirely depending on the user's facial structure. The second half of the review focuses on a series of reversible DIY physical modifications implemented to correct these acoustic shortcomings. By replacing the stock pads with softer, modified Philips Uptown pads, adding felt inside the cups to damp internal reflections, and placing layers of toilet paper and foam over the drivers, the headphone's signature was significantly improved. The pros of this modified version include a...

Summary of the Ultrasone HFI-780 Review The Ultrasone HFI-780 headphones offer a premium visual appeal featuring neat aluminium cups, but they are an absolute letdown regarding acoustic execution. The reviewer heavily criticises their sound quality, ranking them below generic budget gear due to a disconnected bass response and an intensely sharp, raw edge in the upper mid-range. This tonal peak causes vocals to sound highly unrefined and introduces audible distortion that ruins a relaxed listening experience. Furthermore, rigorous channel testing revealed a massive and distracting volume imbalance between the left and right drivers, pulling the bass focus off-centre and entirely skewing the stereo image. Pros and Cons Breakdown While the physical appearance, subtle sub-bass boost (under a tight seal), and somewhat neutral lower mid-range serve as the only notable pros, they are completely overwhelmed by systemic flaws. The technical performance reveals an extensive list of cons: Rough Treble: Resonance spikes across high frequencies.Mid-range Distortion: Spikes exceeding 1% at 2.5kHz, 4kHz, and 5.5kHz cause audible shrillness.Poor Comfort: High clamping force paired with sticky, sweat-inducing pleather earpads.Ineffective Tech: The proprietary "S-Logic" design...

The Ultrasone HFI 780 is a pair of headphones evaluated by Reference Audio Analyzer (RAA) using standardized measurement stands alongside their newer Live Measurement System. Technical data reveals a relatively low average impedance of 41.8 ohms and a high average sensitivity of 115.2 dB/V SPL (101.4 dB/mW SPL) across the 100 Hz to 10 kHz band. Because it requires only 0.055 V_RMS of voltage to achieve a standard 90 dB SPL, the headphones display excellent power efficiency. The testing profile establishes that the electrical phase deviation remains remarkably tight, averaging a mere 0.4 degrees over a wide frequency spectrum. In terms of performance pros, the headphones boast high sensitivity and a benign load profile, ensuring they can easily be driven to high volumes by standard audio sources without requiring massive external amplification. Furthermore, the exceptionally low electrical phase deviation indicates a highly stable, mostly resistive load that will not strain amplifier output stages. On the cons side, the uncompensated frequency response deviates from standard baseline target curves, which will likely require manual equalization setup using RAA's provided target data to...

The Headfonia Three-Way HFI-780 Shootout compares a stock Ultrasone HFI-780 against a professionally modded ALO Audio variant and a custom DIY unit, with the ALO version praised for improved flexibility and smoother treble via a premium Jena cable. The DIY modification, while using rigid, impractical chassis wiring, is noted for delivering superior imaging and a significantly reduced, less sibilant treble response. Pros across the modified headphones include superior, controlled, and less sibilant sound, while the primary cons revolve around comfort, specifically with the DIY model's extremely stiff cable. Additionally, the DIY model is noted to produce a narrower soundstage compared to the other variants. Headfonia

The Ultrasone HFI-780 over-ear headphones deliver a big, bold, and enthusiastic sound that excels with up-tempo music. Built to last, they feature a robust, nicely finished design with a comfortable headband and big, unsweaty earcups that provide excellent isolation and minimal sound leakage outdoors. The headphones include a 1.3m fixed cable alongside a 4m extension and a 3.5mm jack. Sonically, they offer an engaging, detailed, and dynamic performance with a great facility for fine details, making them a thrilling choice for fast-paced tracks. However, the headphones suffer from a fairly confined, intimate soundstage and struggle on each extreme of the frequency range. The low frequencies are notably plump, and while their punch is welcome, they exert a slight squeeze on the lower part of the midrange. On the other end, the treble sounds can turn a bit hard, and sibilance easily creeps in when listening at high volumes. Additionally, they tend to be less assertive and less engaging with sparer, down-tempo, and quiet singer-songwriter-y acoustic music.
