If you’ve used earbuds before, they pretty much all look the same with some minor variations. The dodocool Hi-Res In-Ear Earphones are no exception. The earbuds are attached to each other with a thin cable, and an in-line remote & microphone sits about three inches below the left earbud. As for the earbuds themselves, the ear tips angle in towards your ear, while the earbud is about 1/2″ thick. The cable is sandwiched between a thicker black plastic piece on the inside of the earbud and a thinner silver plastic piece on the outside with a black circular piece inset in the middle. The cable between the two pieces has a small flange that sticks out towards the back of your ear, and an L or R is imprinted on the inside so you can tell at a glance which earbud goes in which ear.

The dodocool Hi-Res In-Ear Earphones are fairly nondescript looking.

The in-line remote itself is simple. The dodocool wordmark is printed on the front, and a single multi-function button and the tiny microphone hole are on the backside of the remote. A single press of the button will play or pause your current track (if listening on a smartphone or other capable device), double press skips to the next track, and a triple press skips to the previous track. For a phone call, a single press answers the call, double press ends the call, and you can press and hold for 2 seconds to decline an incoming call and get back to your music listening. In addition, you can press the button and hold it for three seconds to activate voice control with your device.

The in-line remote features a single multi-function button.

Overall the dodocool Hi-Res In-Ear Earphones are pretty generic looking, but that’s not necessarily a bad thing. When inserted into your ears for listening, they fit nice and snug, are relatively low profile, nice and light, and repeated attempts to shake them out failed. After wearing them for awhile, you almost forget that they are in your ears that’s how light and comfortable they are.

It would have been nice to see some metal components used in the construction, even if just the outside silver piece, as well as a slightly thicker or even braided cable. The earbuds also come with three different ear tip sizes and a hard shell carrying case.


Before we get into sound, we’ll head over to Wikipedia for the definition of Hi-Res Audio:

There is no standard definition for what constitutes high-resolution audio, but it is generally used to describe audio signals with bandwidth and/or dynamic range greater than that of Compact Disc Digital Audio (CD-DA, informally CDs). This includes pulse-code modulation (PCM) encoded audio with sampling rates greater than 44,100 Hz and with bit-depths greater than 16, or their equivalents using other encoding techniques such as pulse-density modulation (PDM).[3]

Although there is no firm definition, Sony describes high-resolution audio devices as those that deliver audio that’s clearer, sharper and more complex than other music sources and closer to the original.

As you can see in the product specifications, the dodocool Hi-Res In-Ear Earphones feature Hi-Res Audio that “provides low-loss signal transmission of 24-bit digital audio with the encoding and playback of music, using higher sampling rates than the standards used in CDs.” So just how do these earbuds stand up to the competition?

When I get a cheaper pair of headphones to review, I usually (unfairly) assume the worst. I’ve been proven wrong more than once recently, and once again dodocool has proved my perceptions of “cheap” earbuds wrong. The sound that comes out of the dodocool Hi-Res In-Ear Earphones is crisp, clear, and has a nice range with decent bass. If anything, these earbuds might have a bit too much on the treble end of things, but it was only slightly noticeable in a few songs and at near full volume — overall it didn’t really detract from the overall sound at all, and it’s something that can be easily rectified with your smartphone’s equalizer.

Even at full volume, there is no distortion and while they are a bit too loud to listen to for extended periods, I didn’t feel like my eardrums were being blasted out. The sound isolation works fantastic as well, with both earbuds in I can’t hear anything going on in my surroundings, and that’s not even with the earbuds at full volume.

Call Quality

As most of us here at Techaeris have mentioned time and again, we don’t usually use earbuds for taking or making calls, but for the sake of testing our test call worked out just fine. Hearing the other party was obviously just fine, and they had little issues hearing me while I was speaking. While the in-line remote is placed fairly decently, holding it a bit closer to your mouth allowed for a clearer conversation.


The dodocool Hi-Res In-Ear Earphones have an MSRP of $34.99USD, and at that price they are definitely a great value for the sound and comfort you’re getting. While I mentioned it’d be nice to have a braided cable and some metal components to add a bit of weight to them, that would drive the cost up a bit but even so I think they would still be worth it.

Even better? If you purchase them before November 30th, dodocool has provided our readers with a coupon code which gives you 50% off, bringing the price down to $17.50 — a price point which you can’t go wrong at for these earbuds. Simply hit the Amazon link in the review box below and enter code FBW72FBA during the checkout process to apply the discount.


If you’re in the market for a pair of new earbuds and don’t want to spend a lot of money, the dodocool Hi-Res In-Ear Earphones offer fantastic sound at an affordable price.
