The Sony MDR-7506 are comfortable, budget studio headphones with a good sound. They're a little cheaply built but they don't leak much, which makes them good for recording. However, they're not the most versatile headphones. They won't stay on your head if you run with them and poorly isolate you from the ambient noise of your environment.
- Good audio reproduction.
- Lightweight and comfortable design.
- Low leakage.
- Poor noise isolation.
- Unstable fit.
- Plasticky and weak build quality.
The Sony MDR-7506 have a simple studio design and a comfortable fit. The wide headband and large ear cups are decently padded, even if the padding material feels a little cheap. Unfortunately, the build quality is slightly weaker at the hinges and although, there's a thin metal frame to strengthen the headband, they don't feel like very durable headphones. They're also not the best for sports or physical activity. They will quickly fall if you run or jog with them.
The Sony MDR-7506 have a straightforward studio design that feels a bit bland but will work for some. The understated, all-black color scheme, is highlighted by a few branding logos. The ear cups are large and oval, and the wide headband is lightly padded and covered in a faux-leather like material. They look a bit cheap and won't stand out in a crowd, but the minimal, and simple style will please some listeners.
The Sony MDR-7506 are comfortable and lightweight headphones. The ear cups are large enough to fit well around most ears. They're not too tight, so they don't get uncomfortable during long listening sessions. However, although soft the padding fabric used, feels a little cheap and susceptible to wear and tear. It also feels a bit rougher on the skin than the padding on some of the more premium models.
These headphones feel very loose on the head. While the lack of tension is good for comfort it makes the fit less stable. They won't slide off your ears during casual listening sessions but they're not meant for physical activity or sports. They will easily fall off your head if used while running or jogging. Also the non-detachable audio cable is a bit bothersome and makes the headphones more likely to fall if it get hooked by something.
The MDR-7506 are decently portable headphones. They're about average sized for an over-ear model, but the foldable design, tightly tucks the ear cups within the frame to save space. They won't be the easiest headphones to carry around on your person, but they will comfortably fit into most bags. Unfortunately, they don't come with a pouch or case.
The build quality on these headphones feels mediocre-at-best. They have a thin metal frame that somewhat reinforces the build, and they're lightweight with dense enough plastic to withstand a few falls without damage. However, these headphones feel a little cheap. The rest of the design is a bit too plasticky for their price and creaks a bit when putting on the headphones. The hinges are relatively weak, and the wiring is slightly exposed which could get damaged through regular use. They're decently built just not as durable as some other headphones even within the same price range.
- 100% Avg.Temp.Difference
The MDR-7506 shine in the sound department. They have a good audio reproduction that has enough bass to feel punchy, without overpowering the instruments and vocals in mid-range. Soundstage is surprisingly decent for a closed headphone, and they rarely had any distortion, even at higher volumes. They lack a bit of clarity and detail with some lead instruments because of the inconsistent high tones but other than that, they performed admirably well with most of the tracks they reproduced.
Very good Bass Range performance. Low-bass is well-extended and very slightly hyped. Bass is also slightly hyped, but virtually flat and quite consistent. This results in a deep and punchy, if a little overemphasized low-end.
Excellent Mid Range performance. The response is mostly flat and quite balanced.
Poor Treble Range performance. Low-treble is decently re-produced, although it is slightly overemphasized and inconsistent. Treble has a 3dB dip around 6KHz which will negatively affect the presence and detail of vocals/leads. It also shows a 10dB broad bump in the sibilance range (around 9KHz) which could make the high frequencies bit harsh and piercing.
- 100% Avg. Std. Deviation
Average Soundstage. Due to the closed-back design, these headphones don't sound very open and immersive. Also, their PRTF score shows that they don't activate the pinna resonance like loudspeakers either and therefore their Soundstage could be perceived to be inside the listener's head.
Decent Imaging. Phase response is decent, although the amount of shift in Bass and Treble Ranges are a bit elevated. Additionally, the L/R mismatch of phase in the high-treble would have a negative effect on the accuracy and stability of the stereo image.
Good harmonic distortion performance. At 90dB SPL, the overall amount of harmonic distortion is low, although a little elevated in the Bass Range. At 100dB SPL, there is rise in the harmonic distortion, while remaining within great values.
Like most passively isolating headphones, the MDR-7506 will prevent some high-frequency noise from seeping into your audio. Unfortunately, it's not enough for the loud, noisy environments of public transit. They won't do well as commuting headphones, but on the upside, they don't leak much, so no one will hear what you're listening to, even in quieter settings.
Poor isolation. These headphones don't have active noise cancelling and isolation is achieved using the closed-back ear cups. They provide no isolation below 400Hz, achieve only 8dB of isolation in the Mid Range and 30dB of reduction in the Treble Range.
Good leakage performance. The significant portion of the leakage lies between 1KHz and 10KHz, which is relatively broad. However, the overall level of the leakage is quite low.
