AfterShokz Trekz Titanium vs Bose QuietComfort 35

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.

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.

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.

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.

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.

The flexible connecting band accommodates a wide range of head/neck sizes. This minimizes pinching or discomfort yet can stay securely on the head.

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.

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.

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.

Bose's noise cancelling tech is quite effective at blocking ambient noise. This will help you fully enjoy the music with little to virtually no outside noise interfering.

With these, you won't have to deal with long and dangling cables that can be difficult to manage.

The QC35s can play music continuously for up to 20 hours. This should cover most of your trips' duration before needing to recharge.

Bose QC35 connects to 2 devices (for media and phone calls) allowing one to listen to music on the laptop and get calls from the cell phone. Allows to change the music provider (laptop or cell phone) automatically. With Sony or Senheiser all you can do is connect media on one device and phone on the other device... functional but really restricted one you get used with QC35.

The QC 35's ear cups and headband feature quality memory foam material which are soft and supportive so they do not pinch on your ears or apply too much pressure to the top of the head. These contact points are also covered with a quality leather material which feels nice and smooth on the skin.

Despite having internal batteries, these headphones are still fairly lightweight, coming in at 235 grams. This makes the QC35 really easy to wear for extended periods and even while traveling.

You can easily control playlist functions using the buttons on the right ear cup. These functions include volume control as well as the play, pause, next track and previous track commands. The on/off switch for the headphones is also on this ear cup.

Aside from Bluetooth connection, you can also connect the QuietComfort 35 to a source using a 3.5mm cable. This makes the headphones usable even with the battery depleted.

Bass is full and punchy. While the sub-bass is not pronounced, there is good and fast bass extension, and this is what gives the music punch and a sense of tightness.
The mids are full and slightly forward so vocals and guitars can be clearly heard.
The highs are clear and do not distort at high volumes. There is a peak on the upper treble which helps to add more detail and clarity to the music, but some may also find the high frequencies to be quite harsh at times.

Multiple microphones are strategically located on both ear cups, allowing for great voice quality when taking calls. The noise cancelling also helps to clean up the voice quality that goes into the headphones.
