Review of the LETSCOM U8I Bluetooth Headphones

Athletic Bluetooth headphones are a dime a dozen. You can find several hundred unique pairs within the $20 to $40 range, and that’s only counting headphones made in the past couple of years.

One benefit to that higher level of competition is Bluetooth headphones have been getting better. Almost like clockwork, the underlying sound technologies have improved, battery life has improved, and design quality has improved.

It’s also how you can get an excellent pair of headphones today for only about $20. With equivalent features, many of these headphones would’ve cost closer to $40 or $60 only a few years ago. And a few even have features that didn’t exist until quite recently.


LETSCOM U8I Bluetooth Headphones

LETSCOM U8I Bluetooth Headphones are in-ear headphones with an ear-hook design. The general idea is to provide the kind of redundant holding forces necessary to keep the buds inside your ear during motion. But they also achieve this kind of security without making grave sacrifices to comfort.

Whenever you’re choosing inexpensive Bluetooth headphones like the LETSCOM U8I, you’re bound to have to make sacrifices in some areas. In this case, those sacrifices are actually pretty small. For example, this headset makes use of Bluetooth 4.1 instead of fully modern Bluetooth 5.0. To most people, these kinds of differences really amount to very little.

Build & Design

LETSCOM U8I Bluetooth Headphones are constructed with an IPX7 certification. That’s actually one of the higher waterproof protection ratings you’ll find on a pair of headphones. It indicates they’re protected from up to one meter of submersion in water. In other words, you can take them in the shower with you and not have to worry they’ll survive.


You’ll notice the U8I makes use of flattened wires for a tangle-resistant design. The cabling itself is relatively short, providing just enough reach to loop around your neck and across your ears. This also means you probably won’t have to deal with a cable clip, though the option is always there.

Aesthetic is a high point for U8I Bluetooth Headphones. Unlike most headphones in this price range, which make use of the same monotone gray-and-black color schemes, the U8I are actually available in a number of different colors.

You can find them in black, blue-gray, green-black, pink-gray, and red-black. The highlighting encompasses both the earbud and its cabling, so color selection is actually pretty significant in terms of visual differences.

Audio Controls

On top of the right earbud, you’ll find a command console. From here, you can control literally anything else the LETSCOM U8I can do for you. The raise and lower volume buttons serve two functions because they can also be used to skip tracks. And the button that separates each volume button is capable of pausing, playing, or handling calls.


Though single-button operation is becoming increasingly popular for devices like the LETSCOM U8I Bluetooth Headphones, some people will always prefer to have the simplicity of a familiar multi-button interface. And managing three buttons isn’t terribly challenging, though admittedly each button is somewhat small.

There’s also a bit of a learning curve involved with remembering which button does which command, and how many times you have to tap. But the whole interface is simple enough that even if you forget what you’re doing, you can generally guess your way to find the right combination of commands pretty easily.

Worn Comfort

Finding comfort from in-ear headphones isn’t as tough as it used to be. LETSCOM Bluetooth Headphones combine in-ear buds with an ear-hook design, which helps to disperse the responsibility of securing the earbuds across multiple components. If you start running or springing, those hooks provide great stability. And if the earbuds do happen to pop out of your ear canal, they won’t go far.


The ear hook manages to keep U8I Bluetooth Headphones right up against your ear, even as you make sudden movements. Though the ear tips themselves aren’t really anything special, they’re not worthy of scorn either. Being made from the same silicone as almost any pair of similar headphones, they tend to meet expectations more than exceed them.

The ear hooks actually make carrying around the LETSCOM U8I Bluetooth Headphones much simpler. You can just lay the hooks over your fingers and carry the headphones with no hassle, and really no need to get a carrying case involved.

Unfortunately, because these are budget headphones, you cannot change the size of the ear hooks. That’s not nearly as important as being able to switch between ear-tip sizes, especially because the included universal hook size will work for most people.

But young children and people with small ears may not be able to get the ear hook to sit correctly. This shouldn’t greatly detract from comfort, though it would make the LETSCOM U8I Bluetooth Headphones less suitable for use during athletic activities.


Audio Quality

LETSCOM U8I Bluetooth Headphones are built around fairly large 11mm audio drivers, and are backed by a CSR chip to help generate a high fidelity audio experience. When you’re shopping for headphones around this price range, you can forget about flawless sound quality. What you’re really looking for is to make sure there isn’t any obvious or heavy distortion.

You might find that kind of thing as you raise or lower the volume of the headset, as you hit the extreme ends of the tonal range. The LETSCOM U8I actually does an amazing job of keeping distortion down. Though much of this is because of digital technologies like Bluetooth 4.1, which guarantee certain levels of sound fidelity.

Apart from getting the essentials right, LETSCOM U8I Bluetooth Headphones makes use of digital amplification to create slightly richer bass. It’s important to temper your expectations, relative to the fact these earbuds are still earbuds, which have never been particularly good at recreating bass tones.

Though the amplified bass used by the U8I Bluetooth Headphones doesn’t have much kick to it, it does provide a smoothness that’s often lacking from headphones which use boosted bass.

Microphone Quality

These days, even a microphone that has no features can perform pretty well with Bluetooth. But the LETSCOM Bluetooth Headphones and its built-in microphone are not totally without noteworthy features.

Perhaps most notably, its microphone puts CVC 6.0 digital noise cancelling technologies at your disposal. Though when you start talking about noise cancelling technologies in the context of headphones, people tend to become confused. The general idea of CVC 6.0 is to reduce noise and distortion within your microphone signal.

For the person who you’re talking with, it sounds as if there’s a consistent ambient noise surrounding you at all times. And the quantity of this noise reduction isn’t small. Though the potency of its effects are circumstantial, it can actually be quite noticeable because it can reduce noise by about 30dB.

For the sake of comparison, a good pair of foam earplugs will block about 32dB. It’s not quite the same as having a cone of silence around you, but it’s unquestionably great for making calls. And it’s certainly far better than having no noise cancellation features at all.


Battery Life

LETSCOM U8I Bluetooth Headphones are made with a built-in 100mAh 3.7V lithium-ion battery. It allows your talk and music playtime to end up in the neighborhood of six or eight hours. But unfortunately, these types of estimates vary depending on many different factors.

Even heading outside while it’s cold could end up dragging down your battery performance. But assuming you’re sitting inside and not listening to your music at full-blast, the six to eight-hour estimate is really quite accurate.

LETSCOM U8I Bluetooth Headphones don’t offer any special recharging features. It takes about two hours to completely restore an empty battery, which is about average for headphones like these. Once you’ve got a battery charged up, it can safely sit around on standby for up to one week.

Wireless Connectivity

As mentioned earlier, LETSCOM U8I Bluetooth Headphones make use of Bluetooth 4.1 for their wireless connectivity. This allows the U8I to provide 33-feet of distance for its connections, provided there are no obstacles between yourself and the source.

It also ensures you get some basic auto-pairing technologies associated with the more recent versions of Bluetooth. All in all, very little to complain about.

Other Considerations

Though you can get by without a carrying bag pretty easily, the LETSCOM U8I includes an EVA bag. The bag is actually close to being a carrying case in its own right. It’s small, circular, and about the size of a CD. It helps protect the headphones from scratches, but it really won’t do much when it comes to fluids.

In addition to the bag, LETSCOM U8I Bluetooth Headphones includes ear-tip replacements in three sizes, a micro USB cable, wire clip, and user manual. The wire clip probably won’t see much use because of the relatively short cable.

But if you’re someone who’s deeply bothered by a little movement from the wire, the cable clip is worth using. It’s a very simple black clip that does not have a tough time blending in.

Finally, LETSCOM provides 24/7 email support and a lifetime warranty. Though it does seem unlikely you’ll need to make use of either.


Who Should Choose LETSCOM U8I Bluetooth Headphones?

The LETSCOM U8I are clearly headphones for people on a budget. With three sizes of ear tips to choose between, comfort basics are covered. Their generally sturdy waterproof design is ready for athletic activities. But the U8I has more to offer than the basics alone.

CVC 6.0 noise cancelling technologies are really what help set these headphones over the top, especially compared to other headphones within this price range. Of course, those kind of benefits aren’t for everyone.

If you don’t care about taking or receiving calls, you could probably find a pair of headphones more uniquely suited to you. But if you have any special interest in making or receiving calls at all, the LETSCOM U8I Bluetooth Headphones are unquestionably an excellent value.

    • Since they are IPX7 rated, they can be submerged in 1 meter of water for up to 30 minutes. While they can be used while swimming, you have to be extremely careful to not go too deep in the water. Also, make sure they don’t fall out – you don’t want these sinking to the bottom!

  1. Hi there, I own a pair of Letscom U81 Bluetooth Headphones and they work great, just recently though after being fully charged can not get a connection with my phone and when it finally does, when listening to something headphones will stop working, I can hear in one ear bud but not the other,or I get a lot of turning on and off without me turning the headphones on and off, I’m wondering if the headphones are about to stop working or is there a battery problem?

  2. I decided to read this article because we purchased these headphones, and I’m confused! If you read the manual that they came with, it warns against using them in or near water! It even warns against high humidity, so how do they have an IPX7 rating?

  3. I have a pair of LETSCOM U81 Bluetooth headphones that were working perfectly yesterday on my run. I charged the headphones after my run then tried to use them this morning but they are not working. There is no red or blue light showing – and they will not charge when I try to recharge them. (The headphones are about 1.5 years old.) I have been using them daily for about a month – prior to that only periodically. What can I do??

  4. I cannot initiate a phone call or use voice activation on my phone by the Letscom headset.
    IT only answers calls or dials the last number or hangs up calls.
    My Plantronic would initiate Google search on my phone by voice. This does not do any voice activation.

  5. The charger for my pair often doesn’t charge them, despite the charger not being bent. the light charging indicator doesn’t turn on no matter what. I rarely ever use them either. Does anyone else have this issue?

  6. I have a pair and I absolutely love them. They are amazing for working out and I love them when I am running, doing schoolwork, going places, etc. I would definitely recommend them to my friends and family.

  7. Is there a indicator to know when the earphones are on or off?
    yes, the light will blink red and blue when on but not connected, blue when on and connected, and when you turn them off they will blink red

  8. I’ve had 5 sets of these. For $18 on Amazon, think of them as throwaway. They’re quite good but they last for 6-12 months.

    I melted two sets charging them before I was told to only use the very short charging cable that comes with them. No problems since.

    The others have all failed when the buttons stopped working, not all at the same time but within a week. I run in them so they get rained on occasionally as well as sweaty, and I assume it’s the moisture causing problems. I suspect you can improve the “waterproofing” by sealing around the buttons with Vaseline or similar. One set accidentally popped open along the seam of one earphone so it might pay to seal that seam, as well. They hold up well in rain for a while (e.g., several marathons) but eventually all of them have failed.

    So far, the seller has cheerfully replaced them under warranty when they die. I’ve never asked for a replacement for a replacement so I’ve actually bought several pairs. The seller has been very responsive when I’ve had failures.

    They do a great job for the price. Music and calls are quite good. Just don’t expect them to last forever. And go online for the extended warranty (2 yrs) that’s been offered with some of mine.
