Product Description
We partnered with Axel Grell—legendary engineer behind some of Sennheiser’s most sought-after headphones—to create a true-wireless IEM with unprecedented audiophile-grade performance. Working closely with Axel’s new brand, grell, we left no feature unrefined. Noise-canceling is revolutionized with grell’s innovative psycho-acoustical Noise Annoyance Reduction (NAR) system. Connectivity is optimized with Bluetooth 5.2 and support for the latest codecs. Communication is crystalized with an advanced microphone array and patent-pending Multilayer Turbulence Eliminator (MTE). And sound quality? It’s best-in-class, thanks to custom-designed dynamic drivers. Introducing the Drop + grell TWS1X IEM: your new true-wireless staple.

We are introducing an exciting new collaboration with the venerable acoustic engineer Axel Grell just in time for the holidays. Anyone who has been a fan of Sennhesier probably needs no introduction, but if you’re wearing a pair of Sennheiser’s right now then there is a good chance that Axel designed them. We were fortunate enough to be able to work with Axel on an exclusive partnership to develop his first independent product under his new company Grell Audio. While Axel oversaw the acoustic tuning of the project, Drop worked to provide a mix of different silicone wingtips to improve the fit and seal in the ear while also designing our own black colorway for the charging case and earpieces. Providing a nice contrast against the blue accent color of the wingtips while maintaining that professional look.   The result is a sleek and modern true wireless IEM with class leading ANC performance at a price everyone can afford. The punchy and warm sound signature gives the kind of listening experience you can enjoy whether you’re on the go or relaxing in the comfort of your home.

We cooked up a little something for your grell audio headphones! We constantly strive for perfection, and to reward our loyal users we have released a new firmware update, now available from the SoundID app!
  • Better connection stability
  • Increased volume range: 4dB (with a change in the SoundID app this will add 7dB in total)
  • Modified tap gesture: 160ms -> 240ms (The "tap" can be longer, more forgiving and responsive!)
  • Simplified ANC and NAR control
  • LHDC "license invalid" fix from Savitech (LHDC is working! And sounds great!!!)

Sonarworks also released a new app update(for both iOS and Android) which includes the following things to improve the Over The Air Update (OTAU) experience:
  • Silent audio playback by our app during OTAU process (The app self-maintains a good data connection to the earbuds)
  • Timeout and retry mechanism for separate stages of OTAU process (if there’s an error, you don’t have to start over from the beginning)

A thank you goes to Sonarworks who have been applying hotfixes since launch, collaborating and working hard with us! Drop has also been here, keeping us informed and pointing us to posts we have missed, as well as being great partners in the sales process. Another big thanks to our patrons (that means you!), we listened to your feedback and this should make your experience nicer! It’s always good to think about what you’re thankful for at the start of a new year, and of course make resolutions 😉 Bonus: Anyone else notice the green “Pairing” knife next to the Bluetooth headphones? 🤣

I'm having issues with the audio and mic when connected to my Surface Pro 8. Not sure what codec is being used, but I notice the audio quality is not quite as good as when paired to my phone. Also, after a while, the microphone quality goes completely down the drain and no one can understand what I'm saying during calls. This only happens when paired to my SP8, it works perfectly fine when paired to my phone.

Quick question… for those used to using AirPods who use IEM’s for more than just listening to music, what are the possibilities of the native sounds (iOS or android) being an option instead of the quick 2 tones the TWS1’s currently use as audio notification. I have different sounds assigned to different actions - so one sound for email received, another for email sent, another for a text received, etc. That hasn’t been an issue with other headphones or earbuds and seems as if it would be an easy update?

So Mr Grell is now CTO for a new headphone company called HEAVYS and trying to sell a new product on kickstarter. Good for him but I wonder what will happen to Grellaudio and the support for the TWS1 I bought. Don't get me wrong but I do not have high hopes any more. One thing is for sure: I will never buy tech on promise any more and also not from start ups.

Bugs report: Bug 1: left/ right single bud no sound after take out from the case. Bug 2: Sound mode is on opposite to each other. When I touch to turn on anc, the left is anc on but the right is still transparent mode. Touch again, the left is transparent but the right is anc on. i have met these bugs several times and have to reconnect few times to reboot.

A bit of an odd behavior that I noticed after a few days of use. Possibly a compatibility problem with Fiio BTA30 Pro. There's an odd behavior when it's paired with Fiio BTA30 Pro. It never seems to automatically reconnect and I had to re-pair it every single time it's removed from the case. It does however, reconnect in the case it went out of range and then back in range of the Fiio unit. I mentioned it may well be compatibility problem because my Sennheiser TWS Momentum 2 reconnects to the BTA30 Pro normally every time it's removed from the case. The fact that the right single tap is so hard to register is one of the reason this problem is so noticeable for me. I always forgot about the problem and ended up returning the unit back to the case for re-pair cause it's so hard to get it to pair mode using the tan-n-hold on the right unit.
DROP TWS1X and grell TWS/1 release notes Hey all! We’ve been working intensively to improve the DROP TWS1X and grell TWS/1 experience on SoundID and monitoring user feedback. Here we have combined release notes for what we have done so far solely on the SoundID app side: SoundID app version 4.2.2 - Fixes in over the air firmware update (OTAU) process where on iOS the update sometimes got stuck - Resolved some crashes that were caused by the BLE library SoundID app version 4.2.5 (Android) and 4.2.6 (iOS) - OTAU process sometimes got stuck if headphones were not connected to SoundID app immediately after pairing them to phone. We added error check for this and if it happens then we guide user to forget/unpair headphones from the phone, pair them again and connect to SoundID app within 60s https://take.ms/iviVB - Fixed a problem where device volume change did affect the ON/OFF state where the effect randomly turned ON or OFF - Added more background retries for all stages of firmware update SoundID app version 4.2.7 (iOS only) - App won’t go to sleep while the OTAU is in progress but user has to stay in the SoundID app while the OTAU completes. Otherwise it will stop updating Also some of you already have reported updating to firmware version 2.3 and as @Evshrug mentioned - the FW update is out via SoundID app and has lots of nice improvements. Additionally we have a troubleshoot/guiding article for Firmware update process for DROP TWS1X and grell TWS/1 here - https://www.sonarworks.com/support/soundid/360003053219-Troubleshooting/360005455159-Troubleshooting/4412951661970-Firmware-update-process-for-DROP-TWS1X-and-grell-TWS-1 For the next releases we will continue to update the user experience. One of the first things will be to implement better UX and UI for the OTAU process where it will be easier to understand the actual states of the update and more clear designs. Feel free to let us know by contacting support if something still is not working out, we’ll be glad to help https://www.sonarworks.com/support/new-ticket?brand=soundid Happy listening

Mine just arrived yesterday. Have been fiddling with some music while working. Overall impression is rather good. I find the transparency mode to actually be better than Sennheiser TWS Momentum 2. I always has an annoying issue that the TWS2 amplified the sound of me stapling documents. Just wished there's some way to adjust the balance between music/outside sound. I'd agree that the should level is slightly underpowered. Strangely it differs with different sources. On my mobile, the levels is ok, while on PC, it's about 1-2 levels below my proffered level (even cranking everything to 100). I would also have liked it to remember the last volume level set, but I suppose if it's different on every device, the current way of it resetting to mid level might be preferred. Can't get SoundID to connect to the unit at all though. Connecting my android mobile to it through bluetooth is fine, but it kept disconnecting itself whenever the SoundID app tries to connect to it. If I tried connecting while playing some music from spotify on the background, it interrupts the music for a second or two then show "Unable to connect". The background music continues.

Upload just worked just now... couldn't figure out what I did different... Note: SoundID app need both "Preference test" and "Hearing test" to sound right. When I just did preference test, it did upload it to the IEM, but for some reason the sound seems fluctuating all over the place. After doing both and finishing upload, it seems to be working well now. Anyone recommending adjusting it further with Custom EQ ? Seems rather good already with the few music I tried thus far. PS. touch control seems to be working better after firmware update, but single tap on the right unit is still seems very hard to register.
Hi @Whispered We are still currently debugging and trying to find out why the upload sometimes fails at this scenario. But until then there is a workaround if it ever happens again (at least these steps worked for us): - kill the SoundID app; - put headphones back in the box - turn OFF and then ON the global Bluetooth switch on your phone - connect headphones again and open back the SoundID app

Updated to 2.3 but after it rebooted immediately my left iem cut out edit: unpaired and suddenly heard “power on” in the left iem. Re-paired and all is good. Touch controls are much better.

I think with firmware 2.3.0.0 these are worthy of the name Grell.

Just got a firmware update today. Not sure what's new since there is no changelog feature. Took me two tries to get the update to apply.
