I find the tuning actually quite similar to my HD6XX or HD58X. Bass might be a bit more pronounced (I am using the foam tips) on the TWS/1 - but overall - if you like the HD6XX the TWS/1s sound very familiar in my opinion - especially voice reproduction is also perfect on the wireless in ears.

Good question, complicated solution!
Our ears are unique, and filter the frequency response of speakers, headphones, and everything we hear. “Neutral headphones” are designed to sound like linear studio monitor speakers. It’s like wearing tinted glasses, but you’re used to perceiving “natural” through that filter. With headphones, an audio engineer (Axel Grell was the chief engineer for the HD 600, by the way) at least knows your outer ear and inner ear will apply the same filter effect to speakers and headphones. In-ear headphones can be designed to emit a linear, flat-measuring sound, but we’re not used to hearing sound that way, without the filter of our outer ears (and different ear tips change the sound significantly as well). Long story short, it’s harder to make in-ears sound like a specific headphone or speaker… out of the box.
If you download the SoundID app, it should come with an alternative tuning that gets reasonably close to a linear sound like the HD 600. However, the secret weapon is to take the intuitive SoundID Quiz, while you’re in a quiet environment, to A/B test and build up a tailored EQ profile that is unique just for your ears! That profile can also be uploaded into the TWS1x, so you can use it with any source you want besides your smartphone, too 😉

A jack hammer is incredibly loud. For the sake of enjoying music for years to come, I will say I was able to fit my pair of grells inside of some over-ear closed headphones, so you could wear cheap ear muffs over your grells for even more noise isolation and better hearing safety.
Super weird experiment that I can’t quite explain: I wore my grells underneath my open-back PXC38X gaming headphones, and was able to somehow chat with friends on Discord wirelessly through my phone while somehow they couldn’t hear the game audio coming from the headphones right on top of the TWS. I suspect the ANC in combination with the directional nature of the grell’s boom mic made this possible, but it felt like sorcery 😅

I don’t currently work for grell anymore, but I felt like my explanation was confusing… so I updated it for better clarity. If you got a grell TWS1x, I hope you did last year’s March firmware update for connection stability, and are still enjoying them today! I still have mine and keep it in my coat pocket; none of the “wings” fit me so I’m thinking of filing down the groove for the wing rings.

How loud is the fan? I've tried to use a power amp before in my bedroom office to listen to music, and the fan would overpower the music when I turned it down.

is there more you need to do to set up the passive speaker than just plugging in the cable from the active one? the manual doesn't mention anything else but i can't hear anything from the passive speaker. windows 11

The audio on my pc38x is not working
One day I just plugged in my Pc38x and they stopped working. I tested the mic and it works, I've tried changing the cord multiple times and have adjusted the volume disk, none of this has changed my situation. I've tested the headphones on my PC, switch, and PS5 and the audio doesn't work there either.

Meze 99 Noir
Heard a lot about these in the past few years, and they sound as good as they look. Deep bass, crystal clear midrange, and solid treble, overall superior sound. Great for multiple genres, special...

Hifiman x Dekoni Cobalt or Massdrop x Meze 99 Noir
Im looking to buy a set of closed back headphones under $200. So far the two main contenders are the Cobalt and Noir. Has anyone compared these two? which seems to be better? Both are around the same price. Ive heard the cobalt is lacking in bass, while thats not ideal im not too worried as I dont often listen to bassy music.

Xduoo Poke II repair
Hi friends, I recently had a mishap with my Xduoo Poke II, that is, it fell out of my hands and now it turns on but the command buttons now work sometimes and sometimes not. I have written several times to Xduoo directly because it was with them that I bought this Dac and to find out what I can do about it but after two months I have not received a response. I live in Mexico City but I would like to know if anyone knows of a technical service in the US that could repair my Poke II and know if it would be worth it for me taking into account the cost of repair and the issue of shipping, or if it is better to think about buying a new portable Dac. Thanks and Cheers everybody.
