[OnePlus App] Add dark mode support

# Outdated. Stay tuned for part 3. [Part 2 - Tuning](https://www.reddit.com/r/Earbuds/comments/1n9m5qn/oneplus_buds_4_review_part_2_tuning/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button) # Intro This a short review of the oneplus buds 4 I got a few days back. I'll go into it in several parts over time and do a deep dive comparing it with my other gear. I'll mostly highlight the strengths of it in this post. # 1 The build is very premium. It immediately looks and feels expensive. Everything is sturdy. The eartips have rubber mesh built in. The opening of the buds has solid metal mesh which I prefer. No flimsy fabric metal combo like the soundcore (curse my aerofits). The eartips have a rough sandy kind of texture which prevents them from welding to your skin. I have really sensitive skin so I can judge eartip materials very well. The material is more like my tangzu sancai tips and I presume also like the sednaearfit max tws. Rough and doesn't stick. Good job oneplus. I'll switch to the sednaearfit max tws6 soon though anyway. I have some sancai wide bore smalls on the way so we'll see how they go. Tangzu sancai smalls DO NOT FIT in the case. Spinfit cp360 and omni mids fit in the case. Cp1025 will fit. # 2 **THE SECURITY OF THE EARBUDS IS TOP NOTCH.** I think this is the biggest strength of the earbuds. It has this magical design that stays in your ears. It will not fall off. It kinda uses the back of your ear as support to keep itself from falling out. I'm very impressed and to me this is very important. Imagine it falls out when I'm trying to onboard the subway *shudder* The seal and fit is good. The shape is good and comfy and I think the buds are on the smaller side. I use S tips and there's a small wiggle room back and forth for adjustment. The buds are capable of creating a seal with its body without relying solely on the tips. I don't fully understand this yet and will explore this further. I have no other earbud or iem that does this. But hey I'm not complaining. # 3 The sound is full range. You can enjoy any and all parts of the sound spectrum with this. The bass extends DEEP and the shimmer goes all the way to the very top, to the edge of my hearing. The shimmer on top is crystal clear and clean. Audiophiles will enjoy this sound because it's full range. You won't miss out on any part of the spectrum. The sound signature is not flat. The balanced profile is kind of a u shape with rich sub bass focus. It's not boomy but for some songs the rumble can be too much. Serenade profile is warmish and quite balanced. I usually use this. On some songs with less forward bass (like who we are from nothing more), the balanced profile SLAPS. There's adequate adjustments to change the sound around. You can get a flattish low end by tweaking around the sound. The baaswave thing is a great utility to apply cut or boost to the low end (200 - 20 hz) I think the sound is audiophile friendly because we have flat gear for when we wanna sit down and enjoy the sound. I have over half a dozen iems, a sennheiser hd 560s for when I want to sit down and focus on the nuances of the sound. When I'm on the go or listening on low volume, the slight boost to the low end is more preferable over flat tuning. # 4 This review is getting too long so I'll get to the main points. I'll address the details in later parts. (Important points in bold) **Buds security is top notch and borderline magical** Buds seal and fit is good and has seal test to ensure a good seal. **Sound is full bodied across the range** **ANC is very strong.** My point of reference is my Sony WH XM4 over ear and my sister's space travel 2. These buds have strong noise cancelation, slightly below the xm4 in moderate and rivaling it at high. I usually use it at moderate intensity or low. In high intensity it is VERY STRONG, stronger than I need and I don't use it usually. Connectivity is good. It has Google fast pair and strong android integration. It shows me the case battery percentage and individual buds batteries straight in the android settings. App is fast and clean. PLEASE ADD DARK MODE WTF. This is 2025. The buds charge fast and the charge holds adequate. Latency is fine, like nothing stands out. The overall experience is fluid and premium and hassle free. # 5 I'll touch a little bit more on the sound. The bass is strong and more growly than thumpy. The focus is on the sub bass rather than the mid bass and this is how I like it. In balanced mode the bass is thiccccc, and phat. It's quite nice tbh. The highs are soothing and clean. It actually sounds less shrill compared to iems or earbuds with an even lower 8k peak (like the soundcores for example) because the lower treble is also present which makes the treble clean and soothing instead of shrill. There is also the presence of very high treble which adds a clean shimmer on top. Do note if you are used to typical consumer audio you may not like this. It has more treble than your average earbud or headphone. I love treble. One of my favorite iems is the tin t3 which has an 8k peak taller than the mount everest and I think it sounds good. If you can't stand treble I don't think this is for you. The treble and bass are both clean and high quality. There is no bit crushiness at the top and no weird muddiness or shit like that. It's clean throughout. The overall sound quality is DRY. It's not a slow wet sound. It's fast and tight. It reminds me of brighter tuned iems with ba drivers. It has a dry sound. I prefer slow and wet sound but this is fine. Tight is good too. **THE SOUNDSTAGE IS HUGE (for earbud standards).** The sound stage is enormous and spacious. IMAGINING IS SHARP. (Thanks to aaron x for pointing me to this earbud. Soundstage is an important consideration for me) The soundstage is on par with things like the waner 2, but smaller than iems like qkz hbb. Imaging is sharper than both of those iems. Imaging is bloody good. I'll touch on something important here. People will talk about earbuds like the space travel 2 and say they have better sound buds like these because they have a better tuning. It's not true. The fact that they have better tuning is true. But where they lose is in terms of technicalities. With cheaper buds you are getting lower quality drivers. With these you are getting higher quality drivers and maybe a more refined tuning albeit less balanced. The effect is much more detail, bigger soundstage and better imaging (this also depends on phase coherence and the nature of the tuning, the positioning and design of the sound channel) and better quality audio like texture, feel, etc. These have a fuller treble compared to the space travel 2. These have **a very high amount of detail.** Thanks to the great imaging, the details are easy to spot and locate as well. These probably use est/piezoelectric tweeters (not sure, oneplus mentioned flat diaphragm whatever that is) which would explain the clean upper end. They don't sound like they come out of dynamic drivers because they sound dry and clean (not necessarily a good thing). The attack is fast and precise and I think the decay is fast too. It feels like ba driver treble. In short, **full bodied sound 20-20k hz, huge soundstage, sharp imaging, tons of detail, dry sound, sub bass focus, clean shimmery top, overall smooth sound signature** # 6 The Bad Let's think about some bad things about it and why it may not work for you. If it doesn't fit your ears, you're out of luck. It's no fun when earbuds keep slipping out. It fits mine and stays in. I has to fk around with a bunch of tips to find out my setup, and I found it quite comfortable with the S stock tips. I may switch to a bigger size on my left ear, but let's wait for the tangzu wide bores to arrive. The bass is rumbly and it may be too much for you. You'll need to eq to use this earbud. At least switch to serenade. There's a lot of treble. If you're used to typical consumer friendly sound, you may not like this because it has good treble extension and it may sound a little sharp to you. I find it smooth. If you want a relaxed sound it's not for you. It's fast and dry and U shaped. But hey that's just a preference. I like wet sticky sound but you can't have everything. You sacrifice the wet sound and get more details in exchange. It's decently relaxing at low volumes though, and the bass helps with keeping things audible at low volumes (huge plus). There's a bunch of mesh and sensor around and I'm afraid they might get clogged. You'll need to take care of it and maintain it. Most Iem tips do not fit T-T Comfort could be better. It's good but you can still feel it in your ear. Maybe with premium tips it will be more comfortable. (Azla sednaearfit max tws6, spinfit omni (<L) , spinfit cp1025 6 month warranty. Would've like 24 months ¯\\\_(ツ)\_/¯ # 7 Credits and review of reviewers ##### S++ Aregina. Lab quality review. Excellent quality. ##### S+ Regan Cipher - The goat of earbud reviewing. Sound sample, anc samples, great discussion, technicalities ranking and an overall likeable guy. Highly recommended AARON X Loud and wireless - Experienced in audio hardware. Great discussion and commentary, provides sound and anc samples, provides **graphs**. Great resources, great guy. Dorx - Sleeper goat earbud reviewer. Spanish only. Reviews and provides samples and **Graphs** for niche models like the redmi 6 or realme air 7. Respect. (reminds me of gekko from valorant) ##### S ##### A+ Picky audio - Doesn't provide graphs or samples and a few information here and there can have mild inaccuracy, but has his own ranking system which is powerful. Provides great critic and lots of information, including but not limited to fit, security and earbud body pictures. Sounds Digging - Provides graphs and deep insight. Only reason not in S is because they don't have a large catalog of reviews and they don't seem particularly passionate about buds. Maybe they are more sound gear oriented. VERY INFORMATIVE however. ##### A De tranquis - no graphs or samples but solid critic ##### B- Kenneth Tanaka - old goat but kinda sold out. Average critic. No graphs. ##### C Beebom/Sillycorn - passable. Almost no information outside of specs ##### F 95% of generic Indian reviewers, generic Spanish and English reviewers here and there. No graph, no samples. Annoying thumbnails, spec reading, ZERO KNOWLEDGE or comparison points, lukewarm safe generic opinion (if you are lucky). They seem like they never actually used the buds. Very little knowledge or passion on the matter. Just Generic scipts, B roll A roll, spec reading, no information,manufactured view farming bullshit. Please stop. # End Thanks for reading. It's getting too long so I'm gonna cut it short here. I'll do some followups later with deeper dive. I have no monetary incentive and this is done entirely out of the love of the game. (not proofreading this huge text wall, comment if you have questions). Have a good day.
