"A good robovac is a life changer. Even a $350 basic S8. It is a great place to start. ... I promise you that you will not be disappointed by a basic S8. It will change your life even if it can't fit under every piece of furniture you own. ... My two S8s just finished vacuuming our entire house in about 46 minutes. ... While my floors were being cleaned, I sat comfortably on our patio in the cool shade with a slight breeze and composed my far too long response to you while sipping a diet soda and relaxing. ... I will have to spend about four minutes maintaining my two S8s. This will be my entire contribution to my home floor cleaning effort for today. Four minutes!"
"Like 500$ these robots are currently the steal of the century ... You can get a mova p10 pro ultra (cannot remove its mops), equivalent to the l40/x40 for 500$ after a discount code"
"I got the Q5 Pro for $139. ... costs $450 less than what I paid for the S6 ... it is the best value option out there imo."

"For gaming, these are perfect. ... As a valorant immortal, tier 2 and premier player, I can confidently say that the imaging and soundstage are spot-on. ... Footsteps, directional cues, and in-game sounds are incredibly precise and natural, giving a competitive edge without any unnecessary bass/treble bloat."
"For gaming the Tea Pros so far are a 10/10, I play mostly Hunt: Showdown and the additional separation, staging, and tighter but punchy bass were all noticeably better for my ears."
"endgame ... Otherwise I probably wouldn't use any other IEM for gaming but this ... The best was definitely the EM6L where I felt nearly no difference in performance with my headphones ... The EM6L is by far and away the best iem for fps gaming. ... But as of rn the EM6L is the best imo ... The EM6L is still king of gaming in my opinion. ... Em6l is still end game."

"I chose the tunable version because I listen to many genres. ... Personaly, i'm using this for variety of genre. ... I tune the switches based on genre to get the best out of it. ... For pop, I go with [ON, OFF, ON, OFF] to bring out warm lows and clear, lively vocals. ... When I listening to breakcore, I switch to [ON, ON, OFF, ON] for more aggressive bass and treble to match the chaotic energy. ... Synthwave feels just right with [ON, OFF, ON, ON], giving a nice retro shimmer and deep punch. ... For the smooth vibes of citypop, I prefer [OFF, OFF, ON, OFF], keeping things balanced and mellow with good vocal clarity. ... And for classical music, I set it to [OFF, ON, ON, OFF] this helps highlight instrument details and gives a more open, natural feel. ... With just a flick of switches, this set becomes a real genre shapeshifter."
"dsp version is like having 7 iems, 2 with the noozles swapping + the free EQ settings."
"overall amazing bass sound and texture ... with the tuning switches set to Up up down down ... with the version with switches you can adjust it to the perfect tuning for you."

"the bass on the Explorer is fuller. ... when you do get that ear rumble, it elicits that reflexive body feeling of a deeper core feeling to it. ... The Explorer is just musical enough to satisfy that for me."
"KZ castor has more boomy bass, so its great if u need more immersive sound with a lot of explosion and gunshot like Battlefield and Squad."
"the OG castor bass are my go tos for anything hardstyle (uptempo, raw style etc) lol, they’re incredible for that"

"For FPS specifically, I was able to pinpoint where gun shots, explosions, and footsteps were, exactly. And these sounds aren’t overwhelming, but I can very easily tell where the direction is, and even “map out,” per se, in my head, where in the area or room I am hearing those footsteps, and aim accordingly."
"The B3 made me hear details for the very first time on songs that I had been listening to for over 20 years."
"To me it became more open, the details got better and the sounds to me have become more natural ... The details became even more impressive to me, the low ends yeah, they decreased a bit but no big deal since I am not really a basshead and yes the tactile bass is still there."

"The subwoofer is boomy as fk as every samsung soundbar subwoofer has been, which stems from pushing too much the sub to mimic how actual subs sound like. ... All the previous Samsung subs were boomy af, this wont be an exception because of the aggressive DSP samsung uses in their soundbars."
"oh so muddy bass"
"But no matter how much I tinker with it I just can't kill the bass. ... for me the bass is overpowering. ... I am not a bass head so might not be the best person to answer this but as far as my limited experience goes they are the most bassiest things my ears have had the pleasure (displeasure) to listen to."

"the Tea Pro are absolutely terrible. ... I couldn't sell them quick enough. ... Utter dogshit & not 10% as good as the Tea 2. ... utter crap with horrific mids, dreadful bass & terrible treble"
"just hurting my hearing"
"They certainly have treble issues ... if OP feels that the Hexa are a bit sharp, he'll feel that with the Tea Pros. I know I did. ... The Tea Pros actually made my ears ring ... if the OP is finding the Hexa sharp, OP'll probably find the Tea Pro a bit fatiguing, too."

"No bass ... Their bass is very very lean."
"vocals are very muted on castor"
"While the deuce has nice bass slam, the rest of the sound lacks resolution. Almost to the point of sounding muffled."

"vocals are very muted on castor"
"that makes the mid range sound thin and/or on the background"
"its also low mid muddy and abit mid recessed"
I had just the OG with Bass , very good The pro with bass is a different beast. If you want relaxed smooth thick bass , the OG is better , the pro has somewhat coloured enhanced mids and all cymbals sound the same . Imagine the old one note bass of cheap speakers , now flip this into treble . I prefer the OG bass than the pro bass
r/iems • KZ Castor Pro: A Quick Impression and Comparison to the Original Castor. ->There appears to be a massive dip in the upper mids low treble on the castor pro bass . Also when there’s a lot of badly constructed treble in the track, the OG sounds better Another thing, at low volumes the OG carries the bass better I have both and like them both , but the OG version plays better on most tracks except where there is too much bass
r/iems • My Quick Review of the Kz Castor Pro (Bass Edition) ->Is the soundstage better than the Hola? My left Hola earbud got damaged, so I'm considering buying a new one. So far, I've only tried the Castor. While it was good, it lacked the soundstage of the Hola.
r/iems • Got a new FiiO JD1 type-C ->just got kz castor bass version yesterday and the left sounded weaker than the right, so I'm returning them. They probably do have a quality issue (which I dont blame since its so cheap)
r/iems • Why almost everyone wants to avoid KZ? ->For me, Wan'er is better than Castors. I've used both and prefer wan'er 8/10 times.
r/iems • Wan’er S.G’s I don’t get the hype ->eh the non bass version of kz castor is okay
r/iems • Which one is the best buy for someone that games & doesn't like too-bassy iems? ->Look at the KZ Castor they are tunable with the 4 dip switches on the back and they sound great and punch way above the price range.
r/iems • Best IEM under $25 for my tastes ->I WHOLE HEARTEDLY AGREE WITH YOUR POINTS: https://preview.redd.it/vwxf7i53neye1.jpeg?width=2377&format=pjpg&auto=webp&s=9aafdf70e38f01e9e6e88692e4c7f79caca103d8 This is MY collection...and I'm very early in the journey. I don't have the budget, knowledge or experience to blind buy a 500USD+ set of in ears that may or may not fit my ears or my preferences. While my journey doesn't completely fit OP's blueprint...I have/had the same thought process regarding purchasing IEMs. Not pictured are the Moondrop Chu 2 and 7Hz Sonus. I started with the Chu 2, 7Hz Zero 2 and Kiwi Ears Cadenza. From listening, watching and reading reviews...I was able to learn about all the terms, labels, and vocabulary to describe what I like or don't like. I threw money at the Wyvern Abyss...I mean...LOOK AT THEM😂. The Kz Castor Bass was a curiosity buy...want to hear if a set touting bass response was really that bassy. My next steps were the NiceHCK F1 Pros, Kiwi Ears Canta and the 7Hz Sonus. The F1 Pros and the Sonu were on sale at the time of purchase...good value and able to narrow things down more for myself. I knew I liked the planar sound...I have a set of open ear planar cans. The F1s felt disappointing (until I tip rolled) The Sonus was about much for my taste (in the mids) The Cantas were quite nice for me. By this point...I had a good grasp of what I was looking for and the direction (s) I want to go in. AFUL Performer 5+2 is currently my go-to...for all around listening. Sourced from R2R DAC lined out into a desktop tube amp. It's like a warm blanket on crisp bright and snowy winter day. I picked up the Hexa because I wanted to hear the hype...and yes...they definitely fulfill the hype and then some. I've EQed my IEMs... especially the planar. They can mimic the sound...but it's only a part of the equation. I now rotate through 3-4 sets at my desktop listening station. The cheapo ones all have 3.5mm out for around the house or for bed. If they break...ill decide if I want to replace. Tip rolling is a journey of itself. Some tips can dramatically change an IEM and rescue it from the bottom of the pile. My Planars now sport foam tips...easing off the treble was huge. Anyway...long post...if you got this far thanks for sticking with my diarrhea of words. TLDR: I agree with the OP
r/iems • How to Actually Learn What You Like in IEMs (and Why One Mid-Tier IEM or EQ Won’t Teach You) ->Hello. I am no means an audiophile and do not have a lot of IEMS tested. Currently owning only KZ castor Harman (Silver) And the improved bass (Black color). If in case i make any mistakes other could correct me. And im only sharing personal experience as a nooby and personal opinion. So since i have switched to the IEMS going to be honest in my personal experience i personally prefer using the IEMS over the gaming headsets. (Only experience before iems was gaming headsets like Corsair virtuoso se, Razer kraken v2, Hyperx cloud 2, and Sony headphones like Sony wh-1000xm3, Sony linkbuds s, Sony wh h910n aka h.earon and some other Sony XB headphones) Reason i wanted to switch to the IEMS was i needed a descent headphones/iems to use with my PC since because of the over ear headphones i had migraines and a lot of of them i had. To the point that i could not play games or even watch the contact im consuming for more then 30 min a day. After switching to IEMS i noticed the sound stage felt a little bigger then the Corsairs i still have and sounded much better with out even using any EQ app on my pc. If being honest i personally doubt that IEMS are leagues a head against higher end Headphones that considered good in audiophile community. Since the IEMS are small there will be limitations. I would even say it would be compering Desktop pc spec against laptop. Similar but not quite. And from what i have read in this group my personal opinion is that the IEMS over 100 maybe even over then 150 have the diminishing returns. If i look at them as a regular consumer then 80% of people might not even feel a big of a difference between iems that cost 150 euros/dollars against any other wireless headphones that consumers buy. But this is only my opinion. So personally since im on a budget i do not see a point buying iems that more then 70 euros (Since im from EU) Becasue a lot of them are definably providing me all i need for musing and playing video games. (Only now considering buying some other options to get a little bit better experience then my KZ castor Harman tuning version) Apologies if i wrote in a mishmash tried to share some experience from a nooby side. And apologies if i have offended anyone.

r/iems • Are IEMs Really That Much Better, or Just an Audiophile Flex? ->It really depends on what kind of sound profile you are looking for. Castor is a more capable iem in my opinion. You should check out frequency response graphs of the iems. It may give you an idea of how they sound. It's explained on the headphonezone website. There are two versions of the Castor, bass (black) and harman (silver). If you want to experience a bass head tuning this can do it well. The bass version is a fun set, not particularly correct sounding. The harman might do a better job of that ( I haven't tried the harman). The stock tips on castors are just okay. I highly recommend latex liquid silicone tips from conceptkart. Polaris is a balanced sound, still a v shaped tuning but not as pronounced as the others. It is easy to listen to but in the end is not as resolving as the castor bass. It can bring out some details but there are better iems that do it well. It is still a great beginner set if you are tight on budget. It has decent levels of bass and fairly smooth treble presentation. Widebore tips are recommended with Polaris. I have not tried the zex, partly because of some reviews mentioning harsh treble. I am a bit sensitive to treble, but overall it should give you an energetic sound. With good amounts of bass and treble. The driver combinations and features are different for these iems.
