Btootos A90
Dual 14.2mm dynamic drivers and Bluetooth 5.4 provide stable, low-latency audio with a 7-hour earbud battery that the case extends to 36 hours. The charging case’s LED display and IP7 waterproofing add practical convenience beyond typical budget earbuds. Best for budget-focused users needing clear ENC call quality and all-day battery life for daily commutes or office calls.
Snapshot
The 30-Second Version
The Btootos A90 sounds way too good for a $25 earbud, but the mic is trash. Get them for music and workouts, not for phone calls.

The proof
Performance
We were genuinely surprised by the sound. The dual 14.2mm dynamic drivers deliver a warm, enjoyable profile that our database puts in the 93rd percentile for sound quality. That's best-in-class territory for budget buds. The Bluetooth 5.4 connection is rock solid and pairing is instant. But the microphone quality is a weak spot, landing in the mediocre range. It's fine for a quick call in a quiet room, but don't expect to take a work meeting on a windy street.

vs Competition
The Btootos A90 goes head-to-head with the EarFun Air Pro 4+ and the Soundcore P31i. The EarFun offers better active noise cancellation and a more premium build, but costs significantly more. The Soundcore has a more secure fit for workouts and a better app experience. The Btootos wins on raw value and that IP7 rating, but loses on mic quality and overall polish. If you just want cheap buds that sound great and can survive a downpour, the A90 is your pick.

Overview
The Btootos A90 is the budget earbud that punches way above its weight class. For around $25, you get solid sound, a battery case with a legit LED readout, and an IP7 waterproof rating that means you can literally rinse these things off after a sweaty workout. The one thing to know? They sound much better than they have any right to at this price, but the microphone is a letdown for calls.
Common Questions
Q: Are these actually waterproof?
Yes, the IP7 rating is legit. You can drop them in a meter of water for 30 minutes and they'll survive. They're perfect for sweaty workouts or getting caught in the rain, just don't go swimming with them.
Q: Do these have active noise cancellation?
Not really. The listing mentions ANC and ENC, but it's mostly software noise reduction for calls. Don't expect the silence you'd get from AirPods Pro or Sony buds. The passive seal from the silicone tips does a decent job on its own.
Q: How do I see the battery level?
The front of the charging case has a digital LED display that shows the remaining battery percentage for the case and each earbud individually. No need to open an app or guess based on a blinking light.
Who Should Skip This
If you take a lot of calls or need a secure fit for CrossFit or sprints, these aren't it. The microphone is a weak spot and the bulky design can wiggle loose. Go get the Soundcore P31i for a better all-around experience with a more reliable fit.
Verdict
Buy these if you want fantastic sound and battery life on a shoestring budget and don't care about taking calls. The IP7 rating is the cherry on top. Just know the microphone is a compromise you'll have to live with.
