Wireless headphones or earbuds are becoming increasingly common especially for smartphone users. They make experiences such as commuting and sports easier due to the portability offered. Such earbuds have been around for at least three years now. Today, we've got one of these for review.

A relatively new entrant in the market is Crazybaby. The Utah based startup likes to market itself as the maker of a levitating speaker. But it also sells wireless earbuds; the Crazy Baby Air 1S and Nano. They're a nifty little pair of gadgets with strengths and weaknesses. The two deliver strongly in some areas but fall behind in others.

Crazybaby's a three-year-old startup with a small employee base, so they will take time to improve.  This company has received a lot of complaints about late or no product deliveries after customers had placed their orders. Outsourcing manufacturing is one of the likely causes behind these delays and the negatives for the Air 1S and Nano you'll see below.


The Air 1S and Nano are Crazybaby's only wireless earbuds. They've got a $60 price difference that is reflected in quality. The 1S is the premium product with a $159 price tag. It's got a better design for the buds but lacks in case quality. Crazybaby's Air Nano is relatively less ergonomic owing to its fat cylindrical form. It takes several tries to ensure a comfortable fit with the buds.

We received our package in 12 days, so delivery times will take longer for Europe and North America. The Air Nano and 1S differ in driver size and sensitivity. The former has a larger 5.5 mm drum which is 0.3mm larger in radius than the 1S'. Their sensitivity differences are also clear as the Air 1S is faster to respond and holds connections with the source better than the Nano.

In broad usability terms, the Air 1S are far ahead of the Air Nano. The earphones perform well as they manage to isolate ambient noise and deliver a thick, bassy sound. The design is intricate and the higher price is likely attributed to manufacturing costs.


Crazybaby Air 1S And Nano Provide An Easy Unboxing Experience But Fail At Case Manufacturing

The Air 1S' and Nano's boxes are easy to open and contain enough ear tips to last a good time of careful usage. The Nano's box is made of plastic giving the package a good and sturdy feel. The Air 1S, on the other hand, comes in a standard cardboard box. Inside the package for the earbuds is a different story. The Crazybaby Air 1S comes with six sports sleeves and ear tips as the company is more generous with the $159 product.

The Nano earbuds come with winged tips that compensate for its awkward design. Cases for both the 1S and Nano need several improvements. The Nano has a magnetic case that opens in the center. It's manufactured out of light plastic which is not great for durability.

The Air 1S has the larger case of two. This is also made out of plastic but features a capped design. You twist the top portion and pull the capsule tray out to place the earphones in it. Neither of the capsules provides storage for the sleeves or winged tips. So you're apt to lose the accessories during a busy commute that requires frequent recharging.


The Air 1S' case is easier to use when placing the buds inside; a problem that will become important once we get to Air Nano's case. However, it's too confusing to open and close. The case features two dots at the top indicating positions for open and close. They both become irrelevant as the top end does not click shut and instead can be spun complete 360 degrees clockwise and counterclockwise.

The Air Nano's capsule features no such problem because of its magnetic design. But it takes practice to place the earbuds correctly inside. Both the 1S and the Nano feature tiny magnetic pins for charging. These need correct alignment with their counterparts inside the case. The Air Nano's case requires several tries to get this alignment right. Additionally, both the cases (and the four buds) lack marking pimples to indicate the correct side. This isn't a major hassle but creates an unintuitive experience which is impossible to manage in the dark.

An integral part of using every wireless earbud is the case. The buds are very easy to misplace, and so require users to carry it with them at all times. Crazybaby nearly fails in this segment as the cases do not add value to the earbuds. Instead, they end up as an irritating distraction. The Air Nano's case will last for an approximate 2-3 charges, while the 1S' capsule delivers around 3-4 complete charges. You can charge both of with any standard USB-C to USB-B cable.


The Crazybaby Air 1S Provides A Fantastic Listening Experience With A Great Ergonomic Build

The Crazybaby Air 1S' design and overall experience make up for the lousy capsule-shaped case. The pods fit tightly inside the ear providing for a rich experience, despite a smaller drum. The Air 1S is advertised with a bassy sound and the product delivers the best that it can. Once the earphones are inside your ear they'll stay there regardless of the amount of activity.

I tested them while running at 12km/h for 2 minutes and 30 seconds. During this period Air 1S earphones did not shift position inside the ear and drained out surrounding noises effectively. Their performance justifies the price tag and a full charge will last you around 3 hours. Lowering volumes will increase battery time, so keep usage scenarios in mind when using these.

Bluetooth connectivity and range is solid. Throughout 11 days of use, the Air 1S did not drop Bluetooth connection. Range radius is between 25-30 feet. It's also easy to use their functions. Pressing the right earbud's will play/pause music playback. Pressing the left will allow you to take/drop calls and open up virtual assistants.

When you're commuting, the Air 1S will drown out the majority of ambient noise depending on the type of music that you're listening to. During physical activities, they will not fall or slip out of place. However, do not rely on these to listen to and answer calls. The microphone does not capture audio sometimes which results in communication problems. The Air 1S is IP86 certified so don't worry about the elements when using them.


The Crazybaby Air Nano Feature An Unimaginative Design That Further Hampers Their Average Audio Quality

The Air Nano are true budget wireless earphones if your budget can include $99. They feature a light plastic case and a thick build. The angled part of the bud's form that features the eartip is too short to reach the inner ear. As a result, the buds do not fit tightly and therefore give a consistent 'loose' feel. The Air Nano earbuds, however, are more portable than the 1S. Their case is smaller and can easily fit inside any pocket.

Sound quality isn't great but it's more than passable. If you're a bass lover then these are not the earphones for you. A lack of bass takes out the depth from their sound resulting in flatter audio. However, using them for calls and play/pause is easier than the Air 1S.

The entire top of the Nano earbuds functions as a button. It's a rare design win for their overall dull form that resembles short and fat cylinders featuring an angled ear tip. Pressing this button is more intuitive than using the one found on the 1S. This is a rare feature that makes using the earphones easier.

I'm not sure whether this is a widespread problem but Bluetooth connectivity on our review unit is not impressive at all. It barely lasted a ten feet radius. Signals also dropped frequently when I had my smartphone in my pocket taking a second or two to reconnect. Battery time for the Air Nano is good. The pair lasts around 3-4 hours depending on music volume.

The earbuds are not easy to use during jogging. Under similar testing scenarios as the 1S, the Nano buds become dangerously loose. This changes when using their winged tips, but once again you're apt to lose the tips. The earphones are splash resistant but not IP68 certified so be wary of the elements.

Crazybaby Air 1S And Nano: The Good And The Bad

The Crazybaby Air 1S and Air Nano have their respective strengths and weaknesses. The 1S earbuds provide a superior listening experience and are well-designed. The Nano earbuds are portable and easier to use due to a larger top-button.

Crazybaby Air 1S: Pros: Cons:
Great sound quality Difficult to use case
Tight fit Short USB-C cable
Good battery life Independent pairing/connectivity
IP68 Short low-battery warning
Crazybaby Air Nano: Pros: Cons:
  Compact case Average sound quality
  Good interactivity Horrible fit
  Good price point Short low-battery warning


For users who love a rich sound experience and want a wireless experience when going to the gym, jogging or undertaking other physical activities, the Air 1S will prove as a good choice. For folks who want good daily drivers, the Air Nano is a compact experience with acceptable sound quality. Crazybaby provided us with review units free of cost.
