Just make sure to wiggle and pull slowly and the cable should come loose.

It is definitely suitable for personal playback. A different sound signature compared to U12t, so we'd advise having a listen at your closest retailer or hifi show. Take a look at some of the descriptions above, which could also be helpful.

See the response above. To add to it though, for performers this means a more forward and impactful response right out of the box compared to U4s. For a wide array of instruments and voices this is an ideal monitoring tool. As someone listening to music playback this can present as a more...

Compared to U4s (m15 modules and spinfit tips) Aspire 4 (using same spinfit tips) has a lot more low frequency punch where as U4s has a deeper fuller bass. Aspire 4 is also more mid-forward compared to how U4s leaves room for the top end air to really shine.

We'll take that as a compliment for how well U4s is priced :) U4s and Aspire 4 are just totally different products with different audiences in mind. The different shell construction, use of the IPX cable, tip selection, etc, all make it a much more useable IEM for live music performances than...

Similar to A2e and A3e, which also don't use our tia™ high-driver Aspire 4 is made to be as cost effective as we possibly could with this driver count and configuration. This means that the proprietary tia drivers couldn't fit that mold. We also wanted to take as much time as needed to perfect...

Great question. As you may notice, we actually offer three custom models (A2e, A3e, & A3t) which range from $499-$899; so we have options for people in and below this price range. There are folks who are just getting into monitoring with in-ears who might not be ready for customs, and don't...

We're very confident that musicians will find Aspire 4 to be one of the best monitoring tools in its class. Very much looking forward to people comparing these two models.

Thanks so much, we're very excited for this big design leap.

Yes it offers similar pressure relief as our other apex implementations. Apex core is an implementation that Aspire 4 inherited from our Duo UIEM. We do not publish FR graphs, but we're sure we'll see measurements published by others soon :)

We're very excited for you to hear Aspire 4, it is available globally through our dealer/distributor network. We'd caution your assessment of IEM quality based on crossovers. The choice to make Aspire 4 a 3-way system was intentional during the development process to make it sound as great as...

Hi All, we want to introduce our new Aspire 4 Professional Universal In-Ear Monitors. Check out the product page to learn all about it: https://www.64audio.com/products/aspire-4

Hello Head-Fi We're excited to have a totally new UIEM to share with you. Welcome Aspire 4 to the 64 Audio lineup of UIEMs: a hybrid four-driver professional monitoring tool. If you're familiar with our products over the years you'll know that since the development of Fourté and U18t we've...

that is understandable, in this case please reach out to support@64audio.com to setup your warranty fit adjustment

We'd recommend using them for at least a couple of weeks to see if it just needs some time getting used to. You have 30 days to let us know if there's a fit issue so take a bit of time first, then let us know if it's still uncomfortable after a little use.

this is something to consider when sending your IEMs in for service. If you're sending them in for a warranty repair or if you pay the service fee (depending on the model/tier you're in) your IEM is fully serviced. This starts with a cleaning, testing, then followed by repairs of any additional...

Duo has LID we just put more of a spotlight on its all-pass filter and unique apex implementation.

Hi, thanks for your question. No it is not possible to convert U12t to A12t.
