Coloud #4 Review FI

Coloud #4 earbuds. The smaller the number, the smaller the headphone.

Bluetooth headphone sales may be up, but that doesn’t mean that everybody is looking for a pair of Bluetooth headphones. There is still definitely a market for wired headphones out there. Not everybody wants to spent a few hundred dollars on a pair of high-end headphones either. Coloud recently re-launched with a line of budget-friendly headphones, and I’ll talk about their three new models in this series of reviews. Up first, the Coloud #4 earbud review.

Ear buds come in a few different shapes and sizes, as I’ve mentioned in previous earbud reviews. The #4 earbuds lean towards the style of earbud that take advantage of the extra room inside of your ear to spread things out a bit, though not as much as some other designs of ear buds I’ve seen or used. The bud portion of the earbud is circular in shape with a slightly domed top. The top of that dome is cut off and the Coloud logo is displayed on the secondary color of each color selection (black/gray, blue/yellow, or grey/splash). The earbud itself is plastic, but it does not have a cheap feel to it at all. When fully inserted into your ears, the shape of the bud makes them just a bit more difficult to remove. You generally don’t want to tug on the cord of an earbud to remove it, but that becomes somewhat necessary with the #4’s.

Coloud #4 Review Detail

The Coloud #4 earbuds have pretty typical ear tips. With four different sizes of tips included you shouldn’t have any problem finding a pair that fit you. Each tip is labeled with its size to easily ensure that you have the right pair. You’ll just want to be sure if you’re using the Large ear tips (as I am) that you don’t see the “L” on the ear tip and assume that is going to be the left earbud, that isn’t what you want to look at for direction. That differentiation is located in small lettering just next to the ear tip on the bud portion of the #4’s. As with most any earbuds you’ll use, you’ll really only need those markers the first few times, and it will be easy enough to know which side is which after only a few uses.

The ear buds are magnetic, and will easily snap together at the Coloud logo. Coloud suggests snapping the buds together behind your neck when you aren’t using them, but it works just as well for placing the buds on a desk, or when storing them somewhere. The size of the earbuds coupled with the angle of their connection is just slightly odd, but the buds are easy enough to insert into one ear, remove the second bud and place into the other ear.

Coloud #4 Review Ear Tip Size

Ear tip sizing is listed on the ear tip itself

The ear buds are attached to a tangle-free flat cord, which is of a sufficient length. The in-line mic with one button control is on the cord leading to the left earbud, just under six inches down the cable. The positioning should work perfectly for most people. At the end of the cord is what is referred to as a ZoundLasso. Zound is the parent company of Coloud, and the Lasso is really pretty fantastic. The 3.5mm plug is at a 90 degree angle, and the plastic from the plug extends a few inches up the cord, where there’s a small hole. When you loop the cord for storage, simply wrap the ZoundLasso around the cord, and insert the 3.5mm plug into the hole to securely store your earbuds and keep the cable from getting wrapped around anything it shouldn’t. All of the Coloud headphones include the ZoundLasso, and I’ll sing its praises in the upcoming reviews for the #8 and #16 headphones as well.

Coloud #4 Review ZoundLasso and Clip

If you read all three Coloud reviews, I’ll gush over the ZoundLasso quite a bit.


When you think of a $20 pair of ear buds, you might not expect too much. If you have that attitude before listening to a pair of Coloud #4’s you ought to be pleasantly surprised. When inserted properly the earbuds fit snugly into your ear, providing pretty big sound. The snug fit offers a decent amount of noise isolation too. The overall mix of sound is pretty good. Bass is strong without being overpowering, and mids/highs are acceptable.

You’re going to find a few corners cut when it comes to budget earphones, and here you won’t find the same sound clarity as you might in a more expensive pair of earbuds. Mids can sound a bit compressed, and highs are muddled at times. At the same time though, you really shouldn’t be disappointed with the sound you will get from these earbuds.

Call Quality

Callers never had any problem hearing or understanding me, and I was able to hear all callers clearly. The button on the cord will answer an incoming call, and then muting the current call, though it doesn’t seem to end an ongoing call. The button does have other mobile music controls though, which while not applicable to phone calls, will be in use during mobile operation.


For $20 — technically $19.95 — these really are a pretty great pair of earbuds. You’ll get good sound and some really nice design features for very little money.
