AKG K391 NC vs Zeus Outdoor

The accessories included are all very useful. You get two 3.5mm headphone cables, a USB charging cable, silicone ear tips, a travel pouch and an airplane adapter.

You can easily replace the 3.5mm cable should it get damaged. You can detach the 3.5mm cable from the control module which is very convenient. Other noise cancelling modules have fixed cables, so you’ll have to replace the headphones should the cable get damaged.

You can take calls with these headphones on. A microphone is integrated into the remote which makes answering calls fast and convenient.

A good amount of noise will be blocked from mixing in with your music. Loud, low-pitched sounds may still be clearly heard though

You aren’t likely to have issues using these on the go. Most active noise cancelling in-ear headphones have large control modules, while the K391NC has a fairly compact and light module. You can easily use these headphones while walking and comfortably enjoy active noise cancelling with your music.

The highs are quite detailed, yet do not get harsh. The mids are slightly forward, so vocals and instruments can easily be heard. The bass is not very powerful but is tight, so you’ll get decent punch from your music.

The Zeus Outdoor combines Bluetooth connectivity, water resistance and active noise cancelling with a thumpy sound signature. These are fun to listen to, convenient to use and can resist damage due to moisture at a good price.

These connect to a sound source via Bluetooth, so only a very short cable connects the two earpieces. This can help improve your mobility and minimize cable-related distractions.

Ambient sound leaking in to your music can be drastically reduced by the active noise cancelling feature. You can better focus on your music, as well as your run/work out.

These have an IPX7 rating which makes them water resistant so they can be used while running, even when it's raining. Do take note that submerging these headphones beyond a certain depth will negate their water resistance.

Bass hits are powerful and forward, which should complement the upbeat and thumping music that most people listen to when working out. Highs and mids are recessed though, so these are best for bass lovers.

Ear hooks are attached to the earpieces which provide extra grip over your ears, so these will not fall off easily. The short connecting cable also minimizes the weight that may pull down on the earpieces .

You get a number of silicone ear tips in different sizes, some foam ear tips as well as a carrying case.

These can last up to 8 hours of continuous music playback.
