Logitech G933 Artemis Spectrum Wireless 7.1 Surround Gaming Headset vs Oppo PM-3

Thick memory foam is used in the ear pads along with a velour material on the surface which feels great on the skin. These pads are also removable and washable, making them easy to maintain.
The headband also features padding with a reasonable thickness so the top of a user's head will not feel painful when wearing these.

The mic design integrates into the left ear cup very well. If you do decide to stow away the mic and push it up, it will look like the mic is just part of the ear cup instead of being a separate unit.

Explosions can sound really good with the G933 as the bass is quite powerful. You'll be able to experience a lot of rumble and punch from the lower frequencies. Also, the upper mids and the highs are quite boosted. This gives a nice thickness and warmth to the sound.
Voices from game dialogue can be clearly heard, while audio details are clear and also easy to distinguish.

The G933 Artemis is praised for its extremely long wireless range, up to 30 feet indoors and even 40 feet outdoors. Stability is also excellent: the wireless functionality doesn't distort the audio quality at all.

The G933 is quite sturdy and has a rugged exterior, but offers good comfort for users. Build quality is also excellent, with a combination of high quality plastic and metal being used in the headset's construction. Also, the it does not have a lot of creaks or unnecessary flex.

With the surround feature activated, sound direction from their various sources is much more distinct. This can help to heighten immersion.

This headset has adjustable lighting, so you can choose a RGB-color in the software suite of the headset. You can also adjust the equalizer, surround sound settings, and you can allocate shortcuts and macro's to programmable buttons on the left ear cup.

The included 4-pole audio cable allows the headset to be used without power, with smartphones or any other device as normal headphones.

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.
