When comparing Shure SE215 vs Sony MDR 7506, the Slant community recommends Sony MDR 7506 for most people. In the question“What are the best headphones?” Sony MDR 7506 is ranked 7th while Shure SE215 is ranked 39th. The most important reason people chose Sony MDR 7506 is:
The bass is just right. It may not have the deep sub-bass extension that bass heads crave for, but what is there is fast, tight and punchy. The mids are clear with a hint of warmth, which make vocals and guitars sound very clear and you can easily hear their sonic nuances . The reproduction of highs is the part that these headphones really shine. They are crystal clear and highly detailed without adding hiss or harshness to the overall sound. Cymbal crashes and pings, for example, are very close to what you would hear if they were played right in front of you.
Ranked in these QuestionsQuestion Ranking
Pro Fantastic sound isolation to block out unwanted noise
The memory foam eartips mold to your ear to provide amazing sound isolation, though there's a bit of a learning curve to using them. You have to press them together before putting them in and then allow them to expand in your ear. Once expanded they will take the shape of your ear and that way provide excellent noise isolation.
The earphones also come with silicon tips which are easier to use than the foam ones and also last longer.
Pro Comfortable once you get used to them
The SE215 earphones have a negative profile, optimized nozzle angle, over-ear fit and memory eartips that ensure the earphones stay in place comfortably regardless of situation. You can even lie on your side with them.
Pro Rich, full sound
Bass is emphasized so there is a good bit of thump while staying controlled. Mids are rich, highs avoid sibilance, though they're a bit rolled off.
Soundstage is okay--instruments are separated out enough for them to not sound like they're all coming from the same place, but it's not particularly wide.
Pro Outstanding build quality makes them long lasting
SE215 earbuds use tough plastic earpiece shells, have a robust kevlar-reinforced cable, a sturdy Y-splitter that's difficult to bend and an L-shaped plug that adds additional strain relief. They won't break if you snag them, drop them or sit on them. They're also completely sweat proof so you can use them while working out without having to worry about damaging them. They're durable enough for professional stage use for which they were specifically designed for.
Pro Thick, replaceable cable
The SE215's 6.4-ft. cable is very thick, and further reinforced at the left/right split point. Reviews confirm the durability benefits of its heavy-duty design. If it ever does break, the cable is built to detach safely from the earpieces, allowing replacement.
Pro Two year limited warranty
Shure provides a warranty against defects in materials or manufacturing for two years.
Pro Will stay in place in the ears
The optimized angle of the earbuds, over-ear fit, and memory ear tips ensure that the earphones stay in place comfortably regardless of situation. These are also sweat-proof, so they're a great option for active use.
Pro Clean and balanced sound with smooth bass and detailed highs
The bass is just right. It may not have the deep sub-bass extension that bass heads crave for, but what is there is fast, tight and punchy. The mids are clear with a hint of warmth, which make vocals and guitars sound very clear and you can easily hear their sonic nuances .
The reproduction of highs is the part that these headphones really shine. They are crystal clear and highly detailed without adding hiss or harshness to the overall sound. Cymbal crashes and pings, for example, are very close to what you would hear if they were played right in front of you.
Pro Reliable headphones due to solid build quality
The MDR 7506 is built outstandingly well, with high quality materials and with little to no creaks and unnecessary flex. These headphones have been around since 1991, which has given Sony a lot of time to refine the manufacturing process of these cans.
Pro Very affordable price for the sound and quality build that you get
Despite being sub $100, the MDR 7506 can compete against headphones up to twice the price. These make for great headphones if you are just starting to get serious about your audio and you want a relatively inexpensive yet quality purchase.
Pro Easy to bring on the go due to the collapsible design
The yokes are collapsible and fold into the headband, reducing the headphones to a much more compact size. Included with each purchase is a synthetic leather pouch for added protection for the headphones when taking them on the go.
Pro Minimal sound leakage due to the closed back design
These leak very little sound compared to other over-ear headphones. The rear side of the ear cups is fully closed, which effectively minimizes sound leakage. With these, you can fully enjoy your music without disturbing people beside you.
Pro Has two separate ports for listening
Con Need some time getting used to
It may take some getting used to memory cables and there's a bit of a learning curve to putting the earphones in with memory eartips. At, first memory cables may seem a bit stiff, but after they're broken in, they're generally more comfortable than typical wires. There's even a wire sleeve that helps form the wire bundled with the earphones to help combat this issue. As for memory eartips--every time before putting them in your ear you have to press them together and then allow them to expand in your ear.
Con Inline mic and volume controls cost an extra $50
The supplied detachable cable does not have a mic or inline volume controls. They can be added by upgrading to the M+ cable.
Con Cable is quite long and non-removable
The headphone cable is coiled and is about 10 feet long. This is great for studios, however walking around in public with these headphones on can be awkward. The cable cannot be removed and has no remote or mic.
Con Can be very picky with audio sources
Due to how accurate sounding these are, you will be able to hear minute details from the sound, including hiss, distortion, and the like. To get the most out of these headphones for music enjoyment, you will want to have a great audio source.
