A Review of the Sony WF-C510 Earbuds

So… These earbuds are kinda meh. TL;DR: the mids are strong, the high end is muddy, the case feels kinda cheap but are actually decent for the price. The good These are cheap. Despite how the label says S$79, these actually only costed S$65, which are actually a steal. These are Sony earbuds, so you do get the Sony software and support, with all the EQ magic they have. The noise cancellation is insanely good. Even without active noise cancellation, the ear tips themselves do absolute magic on any surrounding noise, whether if its wind from a fan, the air conditioner, or whatever else. Having used AirPods Pro gen 1’s previously, I must say that these are 95-98% the strength, without all the head pain from the noise ANC generates. The eartips fit very tightly within the ears, they do not fall out easily. The range is great. The mids are great. If you listen to genres like ChillSynth1 these are perfect. The ‘ambient sound mode’ is incredible (the sound passthrough feature), it really sounds as if you are not wearing earbuds at all and even thhe little details like the volume your earbuds play the ambient sound back at matches the volume of your actual surrounding environment. These things are unfazed by wind. The bad The case feels cheap. The earbuds also feels cheap. There is no ANC, which may annoy some. The case does not actually have any magnets, making opening and closing feel much cheaper. The ugly The trebles are kinda muddy, if you have ever used better headphones you will know what I’m talking about. Say goodbye to vocal clarity, they will be slightly muddy. The EQ only somewhat fixes it. In normal use, it isn’t all that bad. The drivers are only 6mm. Coming from my Pixel Buds A-series’, it is a massive, massive downgrade. The sound isn’t particularly “room filling” nor “full”, it’s just sound. Verdict This was just a quick review, I’m not in the mood of writing anything exciting. Avoid these if you have money, I tried to not burn my wallet this time around but man if I just splurged a bit more, would I have gotten much better sound. If these are the only budget option available, these are not bad, but coming from better audio devices, these aren’t the best. ...

WhatsApp is Bad, Move to Signal

WhatsApp is bad. WhatsApp is evil, and they do not deserve a spot in anybody’s lives. They hate their users. Note that this article will contain swear words. If you can’t handle them, look away :) TL;DR WhatsApp is evil. Meta is evil. They steal your data, they have control over you. This is just a case study; for a change, use Signal. Backstory. Yesterday morning (13th May, around 9am GMT+8) I tried to create a new community on WhatsApp, on my desktop, for an up-and-coming mathematical society at my school. ...

IGCSE Computer Science (Theory) Revision Guide (Full)

Finally?? Yes, this is a little bit delayed, but 3 days before the final computer science paper 1, I’m releasing this guide to help you all study. What is this? This is essentially a bank of notes for IGCSE computer science, the theory part. I will chop up my CSRG G2 semester 1 guide, which has extensive coverage of logic gates and programming, and release it independently, later. These notes are very, very detailed, so it is also a guide to some extent. ...

Stressful Times, with a Math Society on The Side

What? IGCSEs. Cambridge-assessed final examinations. As of writing this article, it is the 5th of May, the night before my IGCSE Coordinated Science (0654) paper 41. They are quite stressful, as you can tell by the title, but it really isn’t all that much. IGCSEs are simple! All you need to do is memorize the markschemes, do past papers and you’re good. Even if you aren’t comfortable with 5 entire topics, you can watch a few YouTube videos and cram all of it the night before! Such an easy life, no? ...

IGCSE Computer Science: Arrays and Iteration Workbook

DOWNLOAD! here Long time no see! Sorry for not posting so much. My workloads been very very heavy; working on projects like this one. IGCSE CS students, look out for the comprehensive whole-syllabus comp sci revision guide soon! I will release it before mocks. What is this workbook? I wrote it because my comp sci teacher let me volunteer to teach. I happily took the offer due to everybody’s cluelessness (they still cannot assign variables). So far I taught 2d arrays in front of the class, and technically this is an assignment only I was set; to make a worksheet on iteration and arrays. It is now a workbook as people need explanations. ...

Don't Write Comments, Write Better Code!

Important Information! If you actually take IGCSE comp sci, ignore everything I say, because the examiners love seeing overcommented code for whatever reason, and they will even give you subjective marks based on if they think there are enough comments or not. To them, “well commented code” is of higher quality, despite if 80% of the code is just paragraphs and paragraphs talking about the meaning of life. Yes, I do have beef with these people. Write better code, comments are not an excuse to write bad code! ...
