This is a review of a counterfeit product. We have tested the real version of these headphones, and you can check out our review here.
The Sony MH755 (Fake) are cheap in-ear monitors (IEM) that are extremely hard to find genuine. Unfortunately, Sony doesn't directly sell these headphones anymore and there's a wide market of third-party retailers with different levels of trustworthiness out there, making it difficult to know if you're getting a real product. We purchased these headphones from a seller on eBay with reviews suggesting them as being possibly genuine. After comparing our unit's performance to other existing reviews and user forums, we verified that our unit was counterfeit. That said, we've decided to review these headphones regardless, as it seems that many users have received knock-off units.

Update 10/07/2021: We've changed our 'Design' photos to better reflect their wear style. The cable leading to the right earbud is longer than that of the left as it's supposed to pass behind your neck. This style allows you to rest the cables around your neck when you're not using them. However, this doesn't change the scoring of this review.
The Sony MH755 Fake Headphones are okay for neutral sound. These headphones are counterfeit and may have a different sound profile than the genuine product. Our model has a very v-shaped sound profile that delivers extra thump, rumble, and boom to your mixes while vocals and lead instruments sparkle. However, some users may find they sound very muddy. A dip in the high-mid can also weaken vocals and lead instruments. Their small, closed-off soundstage isn't very immersive either, but this is to be expected from closed-back in-ear headphones.
The Sony MH755 Fake Headphones are sub-par for commute and travel. While they're decently comfortable, they lack controls and have a really hard time blocking out the low rumble of bus or plane engines. Their audio cable is also quite short, and the ear casing can easily come off. On the upside, they have a decently comfortable fit and are very portable.
The Sony MH755 Fake Headphones are alright for sports and fitness. They're lightweight, very portable, and breathable. They also have a decently comfortable and stable in-ear fit. However, their audio cable is quite short, and it could get snagged on something, which could pull them out of your ears. They lack an IP rating for water resistance, although we don't currently test for this.
The Sony MH755 Fake Headphones are sub-par for office use. They lack controls as well as a mic, and their short audio cable could be annoying for some users. However, they can block out ambient chatter around you and have minimal leakage at high volumes. They also have a decently comfortable fit.
The Sony MH755 Fake Headphones are wired headphones, and you can't use them wirelessly.
The Sony MH755 Fake Headphones are mediocre for wired gaming. They don't have a mic, so you can't talk to teammates. However, their v-shaped sound profile may be suitable for action-packed games as it can help emphasize sound effects in your gameplay. These in-ears also have a breathable and decently comfortable fit. Unfortunately, some users may find their audio cable too short.
The Sony Fake MH755 aren't suitable for phone calls as they don't have a mic.
These headphones are counterfeit and you can see our model's label here.
The Sony Fake MH755 are knock-offs of the Sony MH755, very popular IEMs that are no longer sold through Sony directly. As a result, the primary way to find these headphones is through a third-party retailer. However, due to their simple design and non-descript bulk plastic packaging, it can be hard to tell whether a pair of headphones are genuine if you don't already have them in hand. That said, these fake headphones have a plasticky design and lack more robust features like in-line controls or a mic. They also have a v-shaped sound profile that may be too boomy for fans of neutral sound.
The genuine Sony MH755 are better headphones than the counterfeit Sony MH755 (Fake), which is to be expected. The real pair have a significantly better build quality, a more neutral sound profile, which some users may prefer, and their audio cable is longer. They can also isolate you from more background noise.
The Sony WF-1000XM4 Truly Wireless are better headphones than the Sony MH755 (Fake). The WF-1000XM4 are truly wireless headphones with significantly better build quality, and a customizable sound profile, thanks to their companion app's graphic EQ and presets. They also have an ANC system that does a great job of blocking out ambient noise, and they have an integrated mic so that you can take calls on the go. However, some users may prefer the MH755 (Fake)'s wired design, as they have virtually no latency.
The Sennheiser MOMENTUM True Wireless 2 are better headphones than the Sony MH755 (Fake). The Sennheiser are truly wireless headphones, which some users may prefer, feel better built, and have a more stable in-ear fit. They're also equipped with a microphone so that you can take calls on the go, and they have a companion app that offers a graphic EQ and presets so that you can customize their sound to suit your tastes. However, the Sony are more comfortable, and some users may prefer a wired design to avoid latency issues.
The Beats urBeats3 Earphones are better headphones than the Sony MH755 (Fake). The Beats are more comfortable and have a more neutral sound profile, which some users may prefer. They can also block out more ambient noise and have a mic so that you can take calls. However, the fake Sony are more comfortable.
The KZ ZSN and the Sony MH755 (Fake) are similarly performing headphones, and you may prefer either one. While both headphones are comfortable, the KZ are significantly better built and have a more stable fit. The fake Sony have a more neutral default sound profile, which some users may prefer, and can block out more ambient noise.
The TIN Audio T2 are slightly better headphones than the Sony MH755 (Fake) if you're looking for a less bass-heavy sound profile. The TIN are significantly better built and have a more neutral bass and mid-range, which some users may prefer. The TIN can also block out more ambient noise. However, the fake Sony are more comfortable, and their treble range is more neutral.
The Sony MH755 Fake Headphones have a non-descript look with thin white audio cables and orange ear tips. The right driver's audio cable is noticeably a bit longer than that of the left driver. This design is meant so that you can wear the right cable behind your neck, which helps keep the headphones from falling on the ground when you're not using them. Since these headphones are counterfeit, they may come in other colors.
The Sony MH755 Fake Headphones have a decently comfortable fit. They're lightweight, don't have a deep in-ear fit, and don't put too much pressure on the inside of your ears. However, their cable is very short, and it can easily get hooked on something, especially as the cable is longer on the right side than the left side.
These headphones have an outstandingly breathable fit, which is to be expected from in-ear headphones. They don't trap in much heat, and you shouldn't notice an increase in temperature, even if you've been wearing them during moderate physical activity.
The Sony MH755 Fake Headphones are exceptionally portable. They're small, lightweight, and should easily fit into most pockets or bags without an issue. However, they don't come with a pouch or a case to help protect them when you're on the go.
The Sony MH755 Fake Headphones have a just okay build quality. Overall, they feel cheap and plasticky. The cable is really short, and they lack an IP rating for water resistance. That said, some users have pointed out the differences between this model and the real Sony MH755:
The Sony MH755 Fake Headphones have decent stability. The audio cable is very short, and it's easy for them to get snagged on something. That said, their in-ear fit is pretty stable.
The Sony MH755 Fake Headphones are counterfeit headphones and may not have the same profile as the genuine Sony MH755. It's also important to note that there could be variations in sound performance across different pairs of counterfeit headphones. Since counterfeit headphones are made by a range of different manufacturers, our results only reflect our pair. Also, while there may be genuine products on the market that were made by Sony, there's a potential for some headphones to be 'B-grade' stock and have defects or damage which could affect their performance.
These knock-offs have a very v-shaped sound profile. They deliver extra thump, rumble, and boom to your mixes. Vocals and lead instruments are bright and sparkly, although they seem a bit weak. However, some users may find their mixes sound muddy. They also don't have an EQ to tweak their sound to your liking.
The frequency response consistency is outstanding. As long as you achieve a proper air-tight seal using the assorted tips included with the headphones, you should get consistent audio delivery each time you use them.
The Sony MH755 Fake Headphones have unremarkable bass accuracy. It's overemphasized across the range, resulting in intense thump, punch, and boom. However, some users may find their mixes sound very muddy.
The Sony MH755 Fake Headphones' mid accuracy is good. There's some overemphasis that extends from the high-bass into the low-mid, which makes mixes sound muddy and cluttered. In comparison, the mid and high-mid are underemphasized, nudging vocals and lead instruments to the back of your mix and weakening them.
The treble accuracy is great. The low-treble is fairly neutral, so the upper harmonics of vocals and lead instruments are detailed and present. The mid-treble is slightly overemphasized, which can make sibilants like S and T sounds a bit piercing.
The Sony MH755 Fake Headphones have okay peaks and dips performance. A peak in the high-bass adds extra boom to mixes, which may sound a bit muddy. An uneven mid-mid mostly nudges vocals and lead instruments to the back of the mix, although it can also push their upper harmonics forward. Another dip in the high-mid weakens vocals and lead instruments, while a large peak in the low-treble can harshen these sounds. A peak in the low-treble makes sibilants like cymbals sound piercing.
The Sony MH755 Fake Headphones have an outstanding imaging performance. The group delay response falls below the audibility threshold, resulting in tight bass and transparent treble reproduction. The L/R drivers are also well-matched in amplitude, frequency, and phase response, which is important for accurate placement and localization of objects, like footsteps and instruments, in the stereo field. However, a peak in the phase response's mid-mid may be audible for some users, depending on the content you're listening to. Note that these results are only valid for our unit, and yours may perform differently.
The Sony MH755 Fake Headphones have a bad passive soundstage, which is to be expected from in-ear headphones. Creating an out-of-head and speaker-like soundstage is largely dependant on sound activating the resonances of your outer ear. However, in-ear headphones fully bypass the outer ear. As a result, their soundstage doesn't feel very large or immersive. Since they have a closed-back design, their soundstage won't be as immersive as open-back earbuds like the Apple AirPods (2nd generation) Truly Wireless.
The Sony MH755 Fake Headphones have a good weighted harmonic distortion performance. There are a couple of peaks at both normal and high listening volumes in between the high-mid and low-treble. However, this can be hard to hear with real-life content. That said, the rest of the ranges fall within good levels, resulting in fairly clear and pure audio reproduction.
These are the settings used to test these headphones. Our results are only valid when used in this configuration.
The Sony MH755 Fake Headphones have a passable noise isolation performance. Since they don't have active noise cancelling (ANC), they rely on their passive isolation capabilities to block out sound. That said, while they have a hard time isolating the low rumble of bus and plane engines, they do a better job of reducing ambient chatter. They can also significantly cut down the high-pitched hum of an AC unit.
The leakage performance is excellent. A large amount of the leakage is narrowly concentrated in the treble range and sounds thin. If you're listening to audio at high volumes in a moderately noisy environment like an office, it's unlikely that others around you should hear it.
The Sony MH755 Fake Headphones use a 1/8" TRS cable. However, it's much shorter than that of the genuine Sony MH755. The cable going to the left earbud is 18.9 inches (48cm) long, while the right earbud's cable is 26.4 inches (67cm) long.
These headphones are compatible with PCs when plugging in their 1/8" TRS connector into an AUX port. However, they can only receive audio.
The Sony MH755 Fake Headphones are compatible with PS4 and PS5 consoles when you plug their audio cable into the controller's AUX port. You can only receive audio, though.
The Sony MH755 Fake Headphones can only receive audio when connected via analog to your Xbox One or Xbox Series X|S console.
