The Shure SRH 240 deliver a good enough sound for most listeners but feel a bit cheap when compared to the SRH 440. They're lightweight and decently comfortable but also bulky and cumbersome to carry around on your person. They barely block any noise and aren't versatile enough for other use cases except critical listening and home theater use.
The Shure SRH 240 are decently comfortable headphones with a plasticky and cheap build quality. They do not look or feel as durable as the SRH440, and their cable is not detachable or replaceable, which could get damaged by regular wear and tear. Unfortunately, they also have no controls, they're not stable enough for sports, and they're a bit too bulky to comfortably carry around on your person, which makes them a bit impractical to use outdoors.
The SHR 240 look considerably cheaper than the SRH 440. They have the same headband and studio form factor that works for some but might be a bit too bland for others. However, the ear cups are made of a low-grade plastic that looks cheaper and creaks a lot more under stress than the higher priced model. The ear cups also have a glossy coating as opposed to the matte finish of the SRH 440, so they stand out a bit more but also lose some of the professional studio appeal, which some may prefer.
The SHR 240 are decently comfortable but a bit squeaky. They have relatively large yet lightweight ear cups that should fit most users and they're about as well padded as the SRH 440. Unfortunately, the ear cups do not swivel like in the superior model which poorly distributes the pressure of the fit. It also makes the plastic of the headband and ear cup creak a lot as you move.
These headphones, unlike the higher-end SHR 440 do not fold. This makes them even less portable and a hassle to carry on your person if you don't have a bag. They also do not come with a case or pouch which is slightly disappointing.
The Build quality for the SRH 240 is mediocre-at-best and not as durable as the SRH 440. The materials used in this build feel a lot cheaper than that of the superior model. The headband is still pretty flexible and should be able to handle a good amount of stress but the ear cups are not as dense. They feel more likely to break than the SRH 440 and do not have a detachable cable so they're more likely to succumb to regular wear and tear.
The SHR 240A are about as stable as most over-ear headphones not meant for sports. They're a bit tight which means they won't easily fall off your ears during casual listening sessions. However, they do not have a detachable cable, so they will get yanked off your head if the cable gets hooked by something. They're also not stable enough to maintain a comfortable fit during physical activities. These headphones won't be ideal for running or working out.
The Shure SRH 240A is an average and mid-rangy sounding pair of closed-back over ear headphones. They have a good yet inconsistent Bass, a decent Mid Range, and a well-balanced Treble. However, their Bass could lack sub-bass depending on the user's head shape/size, their Mid Range sounds a bit boxy and their Treble could sound a little sharp on S and T sounds. Additionally, they don't have the most open and spacious Soundstage.
Good Bass Range performance. Low-frequency extension is at 51Hz, which is decent. Low-bass, which is responsible for low-end rumble and thump is lacking by 6dB. Bass and high-bass are within 0.7dB of our target and virtually flat. Also, their bass delivery varies noticeably across users, and is sensitive to the quality of fit, seal, and whether you wear glasses. The response here represents the average bass response and your experience may vary.
Very good Treble Range performance. Low-treble is within 1dB of our target, but carries a bit of the overemphasis from high-mid. Treble is slightly recessed, negatively affecting the presence and brightness of the sound. However, the peak at 10KHz makes the S and T sounds on these headphones slightly piercing and sibilant.
Mediocre consistency performance. In the Bass Range, there is a considerable amount of variation across our human subjects. This is most likely do due to sub-par ergonomics of these headphones that won't allow any swivel for different head shapes. This results in a poor seal on most people. The maximum amount of deviation we measured in the Bass Range is +/-6dB. In the Treble Range, these headphones perform noticeably more consistently.
Decent Harmonic Distortion performance. The amount of harmonic distortion in the Bass Range is elevated, especially in the R driver of our test unit. However, humans are not very sensitive to low frequency distortion. The amount of harmonic distortion in the Treble is quite low, regardless of the level.
The SRH 240 are not suitable to use in loud environments. They don't block a lot of noise and let the low rumbling frequencies of public transit seep into your audio even at higher volumes. Unfortunately, they're also a bit leaky so they won't be the ideal headphones to use at the office or in quieter settings.
These headphones isolate passively using their ear cups. They don't achieve any isolation in the Bass Range, and only 4dB in the Mid Range. In the Treble Range, they isolate the outside noise by about 23dB which is decent, but below average compared to most other closed-back over-ear headphones. The decrease in isolation above 5KHz is due to the poor seal caused by the poor ergonomics of the SRH 240.
