True wireless headphones are now common, and it’s not hard to find them across all price ranges, different sound qualities, different fits, and so on. Now, there’s another company with a new pair of headphones in the ultra-affordable segment. The KuaiFit K headphones come in at $30 — but there are some serious trade-offs to buying them.
Despite the trade-offs, are the KuaiFit K headphones worth buying? We put them to the test to find out.
The first thing you’ll notice about the KuaiFit K true wireless headphones is their design, and they don’t look bad. The earbuds themselves are small and black, with a nice rubberized feel to them. On the cap of each bud, you’ll find a button with the KuaiFit logo, and those buttons can be used to power on the earbuds, control volume, and more.
Interestingly enough, the KuaiFit K headphones are unlike any other true wireless headphones that we’ve ever used — and that’s because of the fact that they don’t have a charging case, and instead charge through a MicroUSB port in each earbud. We’re not fans of that. Not only is MicroUSB now pretty outdated, but the MicroUSB ports in this case seem to be cheaply implemented and could break relatively easy. And, of course, this means that you’ll have to carry the individual buds around in your pocket, making it much easier to lose them, and essentially meaning that you’re stuck with the 3-hour battery life on offer by the earbuds.
In the box, apart from the headphones themselves, you’ll find a charging cable, which splits into two cables to charge the separate earbuds. You’ll also find two extra pairs of ear tips.
The design of the actual earbuds is fine, but we think a charging case is necessary when it comes to true wireless headphones. Sure, these are cheap, but even at least a carry pouch or bag of some kind would be better than nothing at all.
As mentioned, the KuaiFit K true wireless headphones look fine — but are they comfortable? Well, they’re not uncomfortable, but the real problem is that they’re terrible at properly staying in your ears. For starters, it’s a little unclear exactly how they’re supposed to fit into your ears — and once you’ve figured out what seems like the right way, they’ll move a little and one will fall out.
Safe to say, these definitely are not the way to go for those looking for something for sports. In fact, even for daily use, you’ll need to be very careful to ensure that the headphones stay properly in your ears.
At $30, it’s hard to expect an excellent sound quality from the KuaiFit K true wireless headphones — and you won’t get one. Thankfully, however, the sound isn’t terrible.
Let’s start with the bass response on the KuaiFit K true wireless headphones, which is a little weak. This is made worse by the fact that we found it hard to get a good seal, which is very important in getting decent bass.
The mid range, however, sounds pretty good, especially for a pair of headphones in this price range. The low mids are warm and smooth, while the high mids offer enough cut for vocals and enough bite for guitars.
The high end isn’t bad either. We definitely would have liked a better high end extension, but the high end that is there doesn’t sound too bad at all.
The KuaiFit K true wireless headphones connect to your listening device through an unspecified version of Bluetooth, and while we found that it worked fine with an iPhone, we couldn’t connect them to a Mac — which we’ve found can be done with the vast majority of other Bluetooth headphones. That’s a little worrying — it means that the earbuds may not properly connect to other devices too.
The battery life on the headphones sits in at 3 hours, which is a little lackluster. Add in the fact that there’s no charging case, and you may find yourself running out of batteries through the day.
So should you buy the KuaiFit K true wireless headphones? In a word, no. The headphones look fine and actually sound decent, but they’re pretty bad at remaining in your ears and the lack of battery life really makes them something to avoid.
So what should you buy instead? Well, the JLab JBuds Air may be a little more expensive, at $50, but they’re well worth the money if you need a pair of budget true wireless headphones.
