Samsung Gear IconX vs Oppo PM-3

The highs and mids are not amazing, but they most certainly sound good with nice clarity and warmth. The bass is very good. There is a lot of low-end presence with good thump. These will most certainly excel with bass heavy music and are great choices for working out, as the thump will definitely help you stay upbeat.

The Gear IconX has 4GB of internal memory where you can store files like music and play them from just the earbuds.

There is a built in heart rate monitor and you can set these earbuds to tell you exercise-related metrics at set intervals. Also, you can sync the IconX to Samsung's S Health app where you can view fitness metrics.

Once synced with your smart device, you can set which of the earpieces is the primary device. You can do gesture controls on it to control your playlist as well as answer or end calls.

These come with ear tips in three different sizes for you to get a nice and comfortable seal, as well as 3 wing tips in various sizes which adjust how snug these earbuds can be.

A nano-coating is applied to the ear pieces, preventing sweat and splashes of liquid from causing damage.

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.
