Pro Lightweight and comfortable with a near neutral sound signature
The H650 is popular for its near neutral sound, which makes it quite versatile. The headphones can give a great casual listening, gaming, and movie watching experience yet are accurate enough for pro audio mixing. They are also lightweight and comfortable so you won't have any issues wearing them for hours.
Pro Comfortable even when used for hours straight
Clamping force is not too tight. The ear pads and headband feature memory foam which are covered by velour material. The pads feel really soft on the head and allow airflow for minimized heat build-up/sweat.
The headband also features similar cushioning materials and minimizes pressure spots on the head.
Pro Decent soundstage
The open ear cup design allows the sound to blend with your surroundings, giving it a natural width. It will also be easier to identify the direction of sounds, which can really help immersion.
Pro Lightweight for full-sized headphones
The HD-650s do not feel heavy at all. They are usable for long music listening, movie or gaming sessions without feeling pain or strain on their head and neck.
Pro Headphone cable can easily be replaced
While the cable connectors are proprietary, they can easily be removed from the ear cups with a firm pull. The popularity of these headphones means that there are a lot of aftermarket cables that can be bought.
Pro Dark sounding headphones with powerful bass, full mids and slightly recessed highs
The hallmark of the LCD-4's sound signature is the bass. The lower frequencies go quite deep and also have a lot of power. This sound is achieved without bloat or muddiness. Those who prefer powerful yet still fairly accurate bass will definitely love these.
The mids are full, clear and are quite forward as well so detail from vocals or guitars can easily be appreciated.
The highs take a bit of a back seat. While there is still a good level of detail and resolution on the sound, the highs are not as sparkly or airy as other high end headphones. This can be a good thing for some though as this gives the LCD-4 a smoother sound but with less shimmer up top.
Pro Superb build quality
The build is a mix of metal, wood, authentic leather as well as carbon fiber. You can really tell that these headphones are expensive and are built really well.
Pro Soundstage has good width
The open back design gives these headphones good soundstage. Though not the widest, there is a good sense of space and separation to the sound.
Pro Heavy duty detachable cable with solid connectors
The LCD-4's cable is quite thick and hefty which should make it more resistant to breakage and other problems that most thinner cables have. Also, it uses mini XLR connectors which are much more secure as they lock in place.
Pro Ear cups feel really soft and smooth on the skin
It uses authentic leather on the earcups' surface which feel really smooth and supple on the skin. There is also a lot of cushioning thanks to the high quality foam material that is inside the cups. The foam also has acoustic properties that help seal in the sound really well.
Pro Includes a large, hard plastic shell case
The LCD 4 comes with case with ample room and padding inside for the headphones and the cable. While the case will most likely not fit in your travel bag, it will provide plenty of protection to your headphones should you decide to take them out of your home.
Cons
Con Sound leak can be a distraction for others
The open design means that a lot of sound can leak out the ear cups. Other people in your immediate vicinity will be able to hear your music, movie or game, which can be annoying for them.
Con Requires a headphone amp for optimal sound
Plugging these directly to your computer or phone will most likely result in audio that is lacking in volume or may sound too thin. To get the best listening experience, you will need to run these with a capable headphone amp.
Con Very heavy
It weighs around 700 g, and that's without the cable. This makes the LCD-4 one of the heaviest headphones in the market today and will most certainly put quite a strain on your head and neck if you decide to wear these continuously.
Con Leather material on ear cups trap heat
The leather material prevents heat from escaping effectively. This results in heat building up rather quickly around the ears when using the LCD-4, so it's likely that you'll feel uncomfortable after long listening sessions.
Con Requires a powerful amp for optimal volume and sound
Plugging these directly to your computer or smartphone will lead to poor sound, since it requires a powerful amp to get good volume and to output the optimal sound quality that they are capable of producing.
Con Leak a lot of sound
The metal grills on the sides of the earcups do next to nothing to keep the sound within the ear cups. Other people near you will most likely hear what you are listening to.
