Still use my BTR3K. All I want in this entry-level price segment is reasonable battery life and portability. The unnecessary power output and low battery life ruined the BTR15 in my opinion. You shouldn't try to cram in every feature possible in what's meant to be a comfortable tool.

Any info about a BTR3K successor?

Haven't had any issues with my unit. Just purchased it from Amazon (UK). Firmware is 1.22. What should I be on the lookout for? Volume suddenly dropping and going up again?

Does it have a standby function, or should I always switch it off when paired with a PC through USB?

Will the battery be constantly charging when connected to a pc? I would be using it 80% as a desktop amplifier for Iems, so it might be an issue.

I was missing the very first step: push the casing away from the plug, before unscrewing.

Is there any trick I'm missing to unscrew the 3.5 mm to try the 4.4?

Is there a website for firmware updates?

Looking for an IEM with similar characteristics (bold, impactful sound with a wide soundstage and decent detail retrieval), but with comfort in mind. Right now the FH7s seem the best candidates. Any other ideas?

Kind of (only have Momentum 4 right now as far as Sennheier goes). I'll grab a pair from Amazon. A lighter FH9 is all I wanted and right now it was either this or the Xenns Top (which aren't readily available in UK).

I'm thinking about picking up these. I love the FH9s sound but they're just too heavy for long listening sessions... Would I feel like I made a downgrade moving to the FH7s?

Is there an option to completely disable ANC? It's what kept me away from these when they came out (have no use for it and I'm sensitive to air pressure).

Would you say they are a good fit for someone who loved the bold and spacious FH9, but ended up selling them because of the weight and comfort? All I wanted was a lighter and slightly smaller FH9. As far as GIzaudio, I unsubbed a while ago when I realized how shallow some takes where...

That's terrifying. I've read they're trying to follow the FH9's signature, but at the same time I don't think they want to make it obsolete releasing the FH7s. I loved my FH9 but I ended up selling them (too heavy and uncomfortable for long sessions). I don't know. I hope the days of Fiio...

How much do they weight?

How much do the FH7s weight? Comfort, and weight specifically, is the reason I sold my FH9s.

I was trying to decide between XM5 and these, like many people, but being unable to disable ANC is a deal-breaker. I'm also annoyed no review mentioned it. I'm glad I read about it here, because I was going to buy a pair simply assuming it would be an option.

Yeah it's silly. You can't be happy with the sound, have to use different options for each row. I'm perfectly fine with how each component is tuned, but I can't select that. Only things I'd change about the FH9 are the weight of the shell and even more the weight of the cable. Sure, the cable...

I actually had both FH5s and FH9 at the same time and was almost forced to return the FH5s. They are not in the same league. Besides technicalities and specific things about the sound, the tuning of the FH5s is just off, especially compared with FH9 (and that was using a different cable, not...

Can someone with Z1R, MEST and other TOTL iems explain what I'm missing with the FH9? Are there even more details to be found, more... I don't even know because the FH9 right now seem perfect (but that's always the case until you hear something better). I was already surprised by how much...

After 2 weeks without the FH9 and going through FH5s and A4000... I bought the FH9 again. I'll get used to them (initially send them back due to comfort issues). Bought them in silver though instead of black. They feel lighter (don't have a scale with me). Could it be possible? My black ones...

Well yeah. I'm now on the hunt for an IEM with similar soundstage (what I enjoyed the most about the FH9s) but lighter shell. Receiving some FH5s (will be used with a copper cable) tomorrow to see how they feel.

Unfortunately after a couple of weeks I decided to return them. It was only because of its weight. I've always being an absolutist when it comes to comfort, and after years or light stuff like the IT00 (4g) I just couldn't get used to the 13g of the FH9s. It's very unfortunate because I was a...

Alright. I agree with everything said before. This track especially was ridiculous. Green filters with stock spin-fit. It's fun as anything I used, and it gives you all the details without being fatiguing. Impressive. I remember buying the original F9 back in the day, what a journey for Fiio...

Bought a pair, will be with me tomorrow. The main draw was the soundstage. I almost went for the FH5s pro, hoping the cable would really fix them, then I decided to go all in. After being disappointed by the 7hz (comfort issues and almost too technical), I'm curious to see if I can finally...
