AfterShokz Trekz Titanium vs Bose QuietComfort 25

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.

The traveling case is small and provides room for spare batteries and other components. This makes it pretty portable, for those that can't or don't want to leave their headphones at work.

These headphones use a triple-A battery to power noise canceling. Should it run out of charge, it can easily be replaced.

With the feature switched on, you can really zone in on the music. Noise canceling is very effective at blocking out ambient noise, especially the lower frequencies. On a flight for example, engine noise is drastically reduced, as well as most of the sound from the conversations in your vicinity.

The QC25 feels comfortable even after wearing it for several hours. The pads go over the ear and feel soft, as the ample cushioning is covered with supple and high quality synthetic leather. Aside from the usual headband padding, it also has an inner Alcantara lining that feels really nice on the skin.

You have a number of options as to how you want to use these headphones' active noise canceling feature. You can either have the feature on or off while you are listening to music, or have noise canceling on without audio. This is a nifty feature if you just want to enjoy some peace and quiet when in a noisy place.

These headphones will not tire your head or neck out, even if you wear them for quite some time. These are pretty light at around 196 grams.

Sub-bass is a bit laid back, but the overall low-end production is punchy and with good extension. Mids are clear and forward so vocals, guitars and keys sound good with these. The upper treble is boosted, which results in good detail, but can also give harshness to the sound.
Overall, this is a really fun set of cans to listen to, especially if you just want to have a fun music listening experience.
