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 Great sounding wireless bone conduction headphones that are convenient to use
The sound that these headphones produce is comparable to in-ear headphones, so you'll be able to get a good listening experience. These can also connect to two devices simultaneously via Bluetooth, so you'll be able to switch to different audio sources on the fly.
Pro Can pair with two devices simultaneously
It'll be easier for you to switch between the Trekz Titanium's audio sources. These headphones can connect to two devices at the same time, and you can switch between sources at the press of a button. Other wireless bone conduction headphones can only connect to one at a time.
Pro Very good build quality
These headphones are built really well and should last you many uses. The transducer housings are made of high quality plastic, while the neckband features a titanium core with a silicone coating, so it is durable, lightweight and fairly flexible.
Pro Comfortable as these do not go in/on ear
These headphones will not put any strain in or on the ears. These sit just above the area of the ears when worn which could help minimize discomfort.
Pro Lightweight and won't strain the head or neck
The connecting band is thin and light, and both transducers are quite small so not much weight will be applied to a user's head.
Pro Clamping force is just right
The flexible connecting band accommodates a wide range of head/neck sizes. This minimizes pinching or discomfort yet can stay securely on the head.
Pro You can take phone calls with these headphones on
These feature an integrated microphone. At the press of a button on the in-line remote, you can answer phone calls which is very convenient.
Pro Ear plugs are included if you prefer to block out noise
You can opt to use the included earplugs with these headphones. This will result in a music listening experience that is quite similar to traditional earphones where some of the ambient sound is blocked out.
Pro Good battery life
While the headphones advertise a 6-hour battery life, they can easily surpass that threshold if you don't listen to them at full volume.
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 May sound dull or flat to some
The sound that these headphones produce will not wow anyone. Bass is present but sounds quite loose while the mids and highs sound thin. With these, sound quality is compromised in favor of portability, convenience and added awareness of your surroundings.
Con Can cause a potentially uncomfortable tingling sensation on your head
Some experience a tingling sensation on their head, especially when listening at higher volumes. This can be attributed to the bone conduction tech, which uses the bone structure of the face for the sound waves to travel through.
Con Can stop working under excessive sweat
The headphones are IP55 certified and while it generally suggests that they are sweat resistant some users have reported their headphones failing from sweat.
