If you’re searching for the boat immortal 121, you’re likely trying to figure out whether these gaming earbuds offer real performance or are just another flashy budget gadget. boAt markets them as a low-latency gaming TWS with strong sound, powerful LEDs, ENx quad mics and 40 hours of battery backup. The price is affordable, which makes many people wonder if it’s actually good enough for gaming, calls and music, or if there are compromises.
This review breaks everything down in a simple, friendly way so you can understand exactly how the boat immortal 121 performs in real daily use. Whether you’re a casual gamer, a student attending online classes, or someone who wants a stylish pair of earbuds with strong bass, this article tells you everything you need to know before spending your money.
Most buyers also compare the boat immortal 121 with boAt Airdopes 131, boAt Airdopes 121 Pro, and noise gaming earbuds in the same price range. Some are confused about terms like BEAST Mode, ENx technology, and low-latency mode. So this review explains things in simple language along with real-life scenarios to give you a complete picture.
Many users who search for the boat immortal 121 also look for gaming earbuds that offer a balance between style and real usability. That’s because most budget TWS models either look attractive or sound good, but very few manage to do both well at this price point.

Detailed Review of boAt Immortal 121
1. Sound Quality
boAt markets the boat immortal 121 as a gaming-focused TWS, but the sound quality still matters a lot because people use earbuds for music, YouTube, OTT content and calls.
The earbuds come with boAt Signature Sound, which mainly means punchy bass, clear vocals and a loud output. If you listen to Bollywood, EDM or bass-heavy tracks, you’ll enjoy the thump. It’s not studio-level accuracy, but for this price, the sound is energetic and enjoyable.
The earbuds handle high-volume listening fairly well, which is important for gamers who prefer louder sound to catch in-game cues. Even when you push the volume above 80 percent, the audio does not distort heavily, which is a common issue in budget models.
For non-gamers, this means watching movies or streaming shows becomes more enjoyable because dialogues remain clear, and background effects feel lively. While it won’t compete with premium audiophile earbuds, the boat immortal 121 still delivers a pleasant and energetic sound experience for everyday entertainment.
High frequencies are decent and don’t feel sharp. Mids are slightly recessed, which is typical for budget boAt models, but vocals are still clear enough for casual listening.
For gaming:
The soundstage widens slightly in BEAST Mode, making footsteps in BGMI, Free Fire and COD Mobile easier to distinguish. Directional audio is not perfect, but it’s better than regular budget earbuds.
For music lovers:
If you prefer bass-forward tracks, the boat immortal 121 will feel satisfying. If you like classical or acoustic music, the detailing might feel average but still enjoyable for the price.
In short, sound quality is strong enough for the budget, especially for users who enjoy punchy music.

2. Design & Comfort
The boat immortal 121 comes with a gaming-inspired design. The charging case has bold lighting and a futuristic look. The Hulk Edition especially stands out with bright green and black accents.
The earbuds are lightweight and sit comfortably without causing ear fatigue, even during long gaming sessions. The stem-style design helps with stability, and the silicone tips offer a secure fit.
People with smaller ears will also find the fit comfortable because the earbuds don’t feel bulky.
The case is slightly bigger because of the LED lighting, but still pocket-friendly.
LED Lights:
The LEDs are not just for decoration. Many users find them helpful in dark rooms or during late-night gaming sessions because they make the case easier to find.
If you like flashy designs, you’ll love it. If you prefer a minimal look, this might feel too bold.
Another practical detail is that the earbuds maintain their comfort even during longer gaming or editing sessions where you might keep them on for hours. Some earbuds create pressure buildup or soreness, but the lightweight design of the boat immortal 121 avoids this problem well.
Even the LED build doesn’t add extra weight, which keeps the overall feel balanced. This makes them a good choice for students attending long online classes or users who commute daily and want something easy on the ears.

3. Battery Life & Charging
Battery life is one of the strongest parts of the boat immortal 121.
boAt claims up to 40 hours total playback, and in real use, you get around:
- 8–9 hours per charge with 60–70% volume
- 30+ hours with the case (varies slightly with BEAST Mode)
This is very good for the price.
The battery consistency also stands out because the earbuds don’t lose charge quickly when switching between listening modes. Even when you switch on BEAST Mode frequently, the drop is predictable and manageable.
For users who rely on earbuds throughout the day—like office employees or college students—this stability makes a big difference. You won’t suddenly find the earbuds dead during an important call or meeting, which adds to the convenience of using the boat immortal 121 regularly.
ASAP Fast Charging
10 minutes charge gives about 180 minutes of playback. This is extremely useful for students, travellers and gamers who forget to charge their devices.
Example scenario:
You’re about to join a class or gaming session and realize your earbuds are dead. You plug them in for 10 minutes and still get 3 hours of backup. Very practical.
The case charges via USB-C, which is now the standard for almost all modern earbuds.

4. Connectivity & Controls
The boat immortal 121 uses Bluetooth 5.3, which gives stable connection and faster pairing. You open the case, and the earbuds connect almost instantly.
Even in crowded areas like colleges, gyms or metro stations, the connection remains stable for the most part. A few users have reported disconnections, but this is common in budget earbuds and usually depends on device compatibility.
Controls:
You get touch controls for:
- Play/Pause
- Accept/Reject calls
- Switch to BEAST Mode
- Change tracks
The touch area is accurate enough, though like most budget earbuds, accidental touches can sometimes occur.
What also helps is the quick reconnection feature. If you take one earbud out and place it back into the case, it reconnects instantly without delays or glitches. This small detail makes everyday use smoother, especially when you move between tasks frequently.
Whether you’re switching from gaming to calls or pausing a video to speak to someone, the boat immortal 121 handles transitions better than many earbuds in the same budget.
5. Extra Features
Low-Latency BEAST Mode (40ms)
This is the main highlight. BEAST Mode reduces delay between audio and video, which is very useful for gaming.
In BGMI or COD Mobile, gunshots and footsteps sync more closely with the actions on screen. It won’t match wired earphones or flagship gaming earbuds, but for this price, it’s impressive.
Quad Mics with ENx Technology
Calls are decent. Indoors, voices sound clear. Outdoors, the mics do pick up some background noise but still remain understandable. For online classes and meetings, it performs better than expected for the budget.
The LED lighting might look like just a style element, but it also helps during late-night gaming or when using the earbuds in dim environments. The glowing case makes it easier to spot on your desk or bed, which surprisingly reduces the chances of misplacing it.
The IPX4 protection also means you can use these earbuds outdoors in light rain or during sweaty gym workouts without worrying about damage. These small features collectively make the boat immortal 121 more versatile in daily use.

Amazon User Reviews
Great LED design and solid sound
The LED lights look awesome in the dark. Sound is loud with heavy bass, perfect for gaming and music. Worth the money.
Good for gaming but not for classical music
Latency is low and works well for BGMI, but the detailing in softer songs could be better. Still very good for this price.
Battery backup is impressive
I’m getting around 30 hours easily. Fast charging is the best part. Ten minutes charge saves me every time.
Connectivity sometimes drops
Sound quality is great, but I faced minor disconnections a few times outdoors. Indoors it works fine.
Best earbuds for gamers under 2500
Beast Mode is useful. Footsteps and gunshots sync well in COD Mobile. Loved the Hulk Edition look.
A few users also noted that the microphone works surprisingly well during short meetings and indoor calls, even though it struggles slightly outdoors. This mix of experiences is normal for budget earbuds but still shows that the boat immortal 121 performs consistently enough for everyday communication.
