Zeus Outdoor vs Oppo PM-3

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.

Treble is quite detailed, but lacks a bit of sparkle on the highest frequencies as they are rolled off. The mids are just right, not too forward and not too rich. The bass has good presence and punch, but is not very powerful.

Its closed back design along with the fairly thick, leather-surfaced earpads are very effective at keeping the music in and the ambient noise out. This is very useful in tracking situations, and will also help you focus on the audio even when in a busy, noisy place.

The headband and ear cups have fairly thick padding to ease the pressure on the head. These are covered with leather material so they feel smooth.

A headphone amp is not required in order for these to pump up good volume and sound details, so these can work well off of portable devices. There is a noticeable improvement in sound quality and volume when used with a proper amp though.

A combination of high quality plastics and metal are used for these so there is minimal flex and rattles. The headphone joints and yoke also have smooth movement, which make these feel premium when held.

The cables can easily be detached, with 3.5mm jacks as ear cup connectors. This makes looking for new/replacement cables very easy.

Stock cable has an in-line microphone. Not only is this convenient for taking calls while listening to music, but the mic's sound quality is good, with voices sounding clear, full and with good volume.
