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 Good sound reproduction, wireless signal stability and decent noise-canceling for the price
With the BackBeat Pro 2, you get powerful yet clear sound that is comparable to higher end models but at a noticeably more affordable price. Wireless range and stability is quite good and the noise cancelling, while not the best, can reduce a good amount of external noise.
Pro Decent noise cancelling
While the active noise canceling is not the best, it is able to reduce a good amount of noise from your surroundings. Loud engine sounds or high pitched noise may still mix in with your music though.
Pro Clear and powerful sound
The BackBeat Pro 2’s mids and treble are not forward, yet sound clear and neutral. You may hear a bit of sharpness in the higher frequencies, but overall you’ll get a pleasant listening experience with great details from your music.
The low-end is quite emphasized, so you’ll get a lot of thump from bass hits. Bass lovers will likely find these headphones to be up their alley.
Pro Music automatically pauses when taking the headphones off
You won’t need to press a button on the headphones or on your source device to pause the music when you need to remove the BackBeat Pro 2. There are sensors inside the headphones that detect this motion, so the music is automatically paused, and then resumed when you put the headphones back on.
Pro Open-listening mode
Listen to the environment via a microphone without taking off the headphones.
Pro Wired or wireless functionality
These headphones have Bluetooth connectivity for wireless convenience, but you can also switch to 3.5mm wired mode if the battery runs out and you cannot charge right away.
Pro Good wireless range and stability
You’ll be able to hear audio even if you are around 100 feet away from your source device, provided there is a clear line of sight. Signal quality is also pretty good with minimal music cuts and drops.
Pro Very good battery life
These headphones can last up to 24 hours of playback from a full charge, and this with moderate volumes in wireless mode with noise cancelling activated. This is very good battery life, considering other wireless headphones at the price range only have around half the battery life on average.
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.
These headphones may put some strain on your head and neck due to these being quite heavy, coming in at almost 300 grams.
Con Bulky for traveling
These headphones may not be ideal for on-the-go use, as they are large, full-sized headphones that do not fold down to a compact size.
