In that context, Swott’s Airlit 004 is sort of a piece of furnishings manufactured from roughly reduce wooden and offered from a warehouse close to the forest the place stated wooden was sourced. We don’t imply this within the beautiful sense, however within the uncooked sense of the end-product.
We examined the corporate’s TWS earbuds, priced at ₹1,099 on its web site, and ₹2,290 on the field. Right here’s what we discovered in regards to the Swott Airlit 004: crude, uncooked, and missing in fundamentals.
Within the field
We acquired two earphones of their charging pod, the USB-D to USB-C adaptor, ear buds in alternate sizes, and the product documentation.
Design
The Swott Airlit 004 TWS earphones are neat and minimalistic in type. We acquired the Black mannequin to evaluate and have been happy with the clear, subtle matte end of the charging case and flatbed slots for the earphones.
The earphones are manufactured from matte black plastic as nicely, with small flashing crimson and blue lights. The charging case additionally makes use of pinhole lights to present a tough concept of the battery stage.
On account of its massive earphone physique, the Airlit 004 has what seems like a free semi in-ear design, so we didn’t expertise any noise cancellation results. Whereas gentle on the ear canal, it didn’t really feel tight sufficient for strolling or jogging.

Audio
As quickly as you press the charged Airlit 004 buds into your ears, you hear it: a tender however steady high-pitched whine that doesn’t cease if you end up listening to music. This refined but distracting sound that seems like delicate tinnitus turns into a part of each soundtrack. It switches off after just a few seconds when the earphones should not in lively use, however then resumes as quickly as you play one other observe. That is the obvious signal that the Swott Airlit 004 just isn’t but prepared for the market.
We raised this concern and promptly acquired one other pair of earphones to verify if the malfunction was common. The alternative had the very same downside as the unique pair. Additionally, the Bluetooth connectivity of the second pair of earphones was extraordinarily weak. The earphones took a very long time to hook up with a laptop computer.
Coming to the audio, the Swott Airlit 004 delivers a lo-fi sound, including some white noise to no matter media you are attempting to get pleasure from. The impact is very noticeable when listening to quieter movies, equivalent to guided meditation. This implies even the cleanest observe sounds harsh and cluttered.
When listening to music, these TWS earphones end in extraordinarily pitchy and shallow instrumentals. Now add the lo-fi impact and the mosquito-like whine referenced earlier. The general expertise may be in comparison with listening to the ‘on maintain’ music that performs down a cellphone line. The degrees are too excessive, which means you get shrill distortions because the pitch of the track goes up.
Although making and taking calls with the Swott Airlit 004 was comfy because of the earphones’ gentle construct, the audio was crunchy and the quantity ranges needed to be raised to 80% or above as a way to hear others.
The system guarantees it provides “Extraa bass” (with that spelling) however we didn’t discover this to be the case, because of the sound loss. The bass was common with the primary pair of earphones, regardless of the ten mm dynamic drivers. Nevertheless, the second pair of earphones delivered punchy bass.
Day by day use vs specs
The Swott Airlit 004 earphones’ Bluetooth vary is about eight metres. Nevertheless, the system’s contact controls have been patchy. They typically led us to make selections we didn’t need, or summoned Siri and Google Assistant like undesirable genies.
The earphones additionally spontaneously disconnected from the laptop computer a number of occasions whereas we have been testing it, resulting in some awkward moments – equivalent to when vibrant Kollywood music blasted by a quiet room in the course of the night time. The left earphone additionally skilled glitches whereas transmitting the music, and movies have been additionally performed with none sound every now and then. This makes us fear in regards to the lifetime of the system after months if not years of heavy utilization.
The product’s field states that the earphones use Bluetooth model 5.0. We really feel that utilizing a extra superior model would have improved the consumer expertise.
The Airlit 004 is rated IPX4 for water resistance, which means it ought to work as a gymnasium accent with out being broken by sweat.
Battery life
The earphones’ battery life is unbelievable. Nevertheless, there are variations between the battery specs talked about on the product’s net web page and the product’s consumer guide. This needs to be corrected as a way to keep away from complicated the client.
The guide states the product has a continuous music playtime of six hours on a single cost whereas the entire playtime is round 30 hours. These are spectacular stats, however the system’s electrical whirring sound and the white noise impact made it uncomfortable to put on for lengthy intervals. As an alternative, we used the Airlit 004 intermittently for greater than 12 hours over the course of 10 days and located that the charging case was nonetheless going sturdy. The earphones have been virtually totally charged in 10 to twenty minutes. The case additionally received charged in a matter of minutes.
Nonetheless, we might have most popular a counter to maintain observe of the battery stage, just like the one seen on the Airlit 006, retailing at ₹999 on the time of writing. The Airlit 004’s smartphone-based battery stage indicator was removed from correct.
Verdict
The Swott Airlit 004 is a heartfelt try at designing an entry-level TWS earphones product, however one that’s not but prepared for mass use. Hardy travellers and voyagers will want extra dependable Bluetooth connectivity for his or her earphones. Music lovers will likely be delay by the pitchy sounds and lack of audio element. Working professionals will consistently be elevating the quantity whereas taking calls. Gymnasium goers will battle with the free match. On a regular basis customers will likely be cringing on the electrical whine and grainy audio of their ears. Total, the system’s lengthy battery life doesn’t cancel out a substandard listening expertise.
The Swott Airlit 004 will likely be relegated to that pair of backup earphones you allow on the backside of your bag simply in case you overlook your favorite set.
