[Updated] Overall you really get what you pay for. They serve the purpose of a decent pair of tws for basic quality calls and music listening. Main problem I noticed was with the pairing and connection strength as they routinely lose signal for no apparent reason. Once or twice I had issue of only one of the buds getting paired and had to reset the other one to get it paired.If you have paired these to one device and try to pair to another one without disconnecting from first it simply doesn't work. This is starting to get annoying but maybe I'll get used to it. We'll see.----------------------------------------------------------This is just day 1 review of these. Got them for Rs 898 on some offer on Amazon. I'll post updates later on. Hope this is helpful for anyone interested.Package : The packaging is quite decent for such a low price. Comes with the tws earphones fitted with medium earplugs fitted inside the case. Also included are a very short USB c cable and two additional earplugs - small and large. Package includes some Noise stickers and a pretty good user manual and warranty instruction card.Build : was immediately dissapointed with the plastic case as the lid was rattling and not confidence boosting. Will use it for a while to see if my worries are unfounded. The earphones themselves are rather sturdy feeling in hand. They fit very snuggly into the case and there is no evident feel of them coming lose or rattling within the case.Comfort : This is very subjective and each ear is different. It's one of the reaonss I wanted to get a cheap tws to see if I'm OK with the form factor for long hours. The prefitted medium size earplugs were not comfortable so I switched to the small size ones. And after about 20 mins I forgot I was even wearing them. The earbuds are very lightweight owing to the plastic build but upside is that they don't cause any strain even after an hour of continuous use. One thing to note is that if you have "Gandhi" ears then the fit might be a little awkward - I should know. My ears covered the touch areas of the buds so I had to fiddle around a bit if I wanted to do any of the touch actions. YMMV.Sound quality : I liked them. I'm no audiophile but they have decent volume and satisfactory levels of bass and separation. I tried my usual test at https://youtu.be/J0a2Prc_MQo and they fared quite well. The treble maxes out at 15khz post which you hear nothing at all but this is to be expected at the price point. There was noticeable vibrations creeping in at below 30hz but the L and R drivers seem to be matched well and all of the panning tests were quite decent. I feel this definitely punches above its price point.Call quality : In a low to no outside noise environment the microphones were very good. There was no lag and the person on the other side said my voice was very clear. But things take a steep fall as soon as little noise is present and you start sounding like you're inside a well. Seems the mics can't figure out how to filter out your voice so they end up trashing the call quality. Overall you get what you pay for here.Range : max I got was around 5m. Not sure how they tested and got 10m as advertised. Any disruptions like a wall will simply break the connection but they connected back automatically every time so far so I guess that's passable.Pairing :------ UPDATE on 12th Aug 2022 - - - - - -Major issue here is that if already paired to a device like a laptop they simply are unable to be paired to another device like your phone. You have to unpair from the first device and then try to pair again. Had issues like only one of the buds pairing as well.Have to fiddle around to get it to work and is not convenient.---------------I don't have a phone to test the fast pair features - Actually I'm not even sure these support it. Anyway, the earphones go into pairing mode as soon as you remove them from the case and I was able to pair with no problems on multiple phones. They will auto pair post this initial setup to previously paired devices. I could not find any way to control the pairing mode though. You have to live with what it comes with as there is no app or anything to control what it does. They switch off pairing mode once you put them in the case so hopefully that means the battery would be saved a little.Battery life : Way too early to tell anything. Will share my experience post one week and one month. But they came around 80% charged in the box and I have stated to charge the case - Box says it will take 2hrs to fully charge it and there are basic indicators like a flashing red led for charging which turns solid red once done. The earphones also have LEDs that blink red & white to indicate pairing, low battery etc.Sync issues : None so far. But have seen many such reports and reviews wherein the L and R earphones seem to go out of sync on similar low price TWSes. So will see if I face any such problems.These are the primary areas that I am concerned with while evaluating any TWS so will share how my experience is after a while. So far I'm happy with them.
