Closed-Back Planar Magnetic Headphones (circumaural)

The first thing you may ask is “what does planar magnetic mean?

binäre optionen einkommensteuer It’s a fair question as there aren’t many planar magnetic headphones around. What it refers to is the way the drivers generate the sound you hear. A traditional dynamic driver sends a signal through a coil of thin wire that reacts with a magnet causing it to move back and forth to push the air and create the sound waves that you then hear as audio. Essentially a scaled down version of a standard speaker. With a magnetic planar driver, there are a series of magnets on either side of a thin diaphragm that generate a magnetic field that in turn moves the diaphragm to create those same sound waves. Having magnets on both sides gives much better control of the diaphragm thus allowing a more precise movement and in turn clearer audio. The downside is usually that due to all those magnets they are much bigger and heavier than a dynamic driver so until recent times were not suited to being used in headphones.

migliori strategie opzioni binarie Build quality is outstanding.

billigaste Viagra i sverige Metal construction and faux (but very luxurious) leather padded cups exude a refined classiness that makes them look good no matter where you are or what you are doing. Designed to be portable headphones they are strong and flexible and I’ve not once had any fear that I might break something even when stretching them across my large skull. Even with all that technology jammed in they are relatively compact which is ideal for a pair of portable headphones. They felt heavy to start with but I’m used to my pair of Sennheiser HD558’s which are extremely light in comparison. After a few listens I stopped noticing the weight altogether and instead they just felt solid, familiar and comfortable. A removable cord to the left ear cup provides the connection to your music. The fact that this is a standard 3.5mm jack rather than a silly proprietary set up means no difficulty in swapping cables with something that suits your needs and can be easily replaced.

futuros y opciones financieras My modest but very functional set-up.

bästa binära optioner mäklare As these are a portable headphone I have paired them with the OPPO HA-2SE headphone amplifier and DAC and my audio source is my old Sony Xperia Z2 phone that serves purely as my music player these days. USB out and a micro SD card full of lossless files makes this ideal for getting out and about without having to compromise on audio quality.

dispense per imparare il trading gratis Paired with the OPPO HA-2SE portable headphone amplifier and DAC these headphones really come to life. Playing lossless files via USB to the HA-2SE makes for impressive clarity and a warmth of sound that really puts you in the middle of the action. Bass is punchy and deep and has a strong presence without overpowering the midrange and highs. If you are looking for massive bass I’d suggest trying them first as they do deliver a good amount of bass but you’ll find alternatives that will deliver a lot more. The midrange is solid and clear. OPPO describe the sound signature as being very natural and balanced, with plenty of emotion and impact. For the most part I agree. I have a very eclectic taste in music so finding headphones that suit can be a little tricky if you want to enjoy everything you throw at them. This is where the PM-3 sets itself apart from other high end headphones. Even when plugged directly to my phone with no additional amp or DAC they do a great job. Soundstage is good for a closed back headphone and even though these are intended to be portable headphones you’ll find they do a fantastic job in any setting. The soft ear cups seal nicely against your head creating some of the best noise isolation I’ve ever experienced on a headphone that doesn’t have active noise cancellation. Leakage is minimal as well so you won’t bother the people around you.



binaire opties echt of nep Music is an artform and surely deserves to be heard the way the artists intended.

Good quality audio gear with a good quality source truly needs to be heard to be appreciated. Most people are listening to highly compressed audio and don’t know what they are missing. I gave a friend a listen to a track that she had been listening to a lot and she was amazed to discover there was a piano playing that she had never heard before. She was blown away. Before this she had been using some $10 headphones playing MP3’s from her phone and couldn’t understand how someone could pay hundreds of dollars for headphones. After a few minutes with the PM-3’s she was reminiscing about younger days when she would just sit and listen to music for enjoyment rather than just to drown out the sounds of life. For many people this is something they have forgotten how to enjoy and that’s in part due to the abundance of low quality audio sources and cheap headphones that we have become so accustomed to. Once you hear good audio you won’t want to go back. The earbuds that came with your phone and an MP3 track is a small and convenient way to listen to music but it’s the equivalent of going to a concert and listening to the whole show from the toilets.


opzioni binarie il sole 24 ore The verdict.

The OPPO PM-3 offers an exceptional listening experience. Easily driven by portable devices and even better with an amplifier they will remind you how good music is for the soul. Being magnetic planar headphones gives you a great talking point and sets you apart from the crowd with all that technology sitting on your head. They look good, they’re comfortable and they sound amazing. You will not be disappointed. I didn’t want to send them back, so I bought them…
