The Rosewill EX-500 actually makes a really good impression in terms of design. The aluminum housing gives off a good, cold feel and has a nice weight. At 19g, they are not the lightest, but still well within the norm. Right out of the box, they come equipped with the medium-sized standard variety of tips.
The body comes in two parts, with a thin plastic element between them. The cable is secured well to make sure you won't have to worry about damaging something if you were to yank them out of your bag or pocket, for example. The rear sports the Rosewill Music logo and has a diamond-cut edge, which adds to its overall looks.
Taking a look at the bare in-ear, you can see the R/L labels on them, which is helpful as the EX-500 is not symmetrical. The opening on which the tip goes is rather compact, and the filter seems glued into place in a somewhat crude fashion. But thanks to the standard shape of the opening, you should have plenty of choice when it comes to using aftermarket tips of your liking.
Rosewill EX-700
The Rosewill EX-700 looks quite different from its more affordable brethren, slimmer and slightly longer. The biggest advantage of the design is the lighter weight of 16g and symmetrical design. You could, as such, just jam them into either ear and they will fit.
The aluminum housing consists of two parts as well, but there are no visible plastic elements holding them together. In essence, the housing is as big as a medium tip, and you will find a mention of which channel you are holding on the rubber part protecting the incoming wire. As with the EX-500, the rear of the housing holds a Rosewill Music logo and comes with some diamond-cut edges as well.
Looking at the bare in-ear, it looks much cleaner with the metal-mesh filter snug in place and level with the housing. It seems the EX-700 is generally constructed better.
Comparison & Common Components
Comparing both ear pieces, it becomes obvious how slim the EX-700 is compared to the EX-500. Also, the opening of the more expensive model is larger, which should help with sound quality.
Both in-ears come with a pretty standard microphone. When used with a mobile device, you may pick up or hang up on a call with a short press, while a long press brings up Siri or the Google Assistant. During audio playback, a short press will pause or play, two quick taps will forward to the next song, and three quick presses will rewind to the previous title. You will find the actual microphone inside the black housing behind a little opening.
Rosewill has equipped both in-ears with an angled plug with a reinforced design around the 90° bend. This means that you won't have to worry about any strain put on that element. Naturally, with in-ears of this caliber, the plugs are gold-plated. To add to their overall sturdiness, the split between the left and right channel is quite large and sturdy. It is placed well, which ensures that users with larger heads will still be able to use these in-ears comfortably. Lastly, looking at the cable, you can see the various embedded leads which are twisted for added strength and quality.
