    Liking the 480 because of the better FR in the treble and detachable cable. Fixed cable is a turn off for me. Please keep us informed!

    ya I suppose if enough people say stuff about the fixed cable maybe Dunu can do a revision. Cus the sound is on point. It sounds great but I hear you on the cable.

    Sorry...what I meant to say was that the 380 is a turn off because it has a fixed cable. I like the 480 more because I can cable swap.

    DM-480 looks very similar in appearance to TRN IM2.

    Yeah, the shell looks extremely similar to that, the trn H2 and the ash. Wouldn't surprise me if it's the same, I'll know whenever I get my pair I guess... Wouldn't surprise me if they hone in on some "best" designs as far as 3d printed shells go.

    It's definitely possible. The other earphones that have shared the same base shell as the DM-380 have removable MMCX cables as an option. However, we built the DM-380 initially to satisfy the needs of a large distributor in which we have an exclusive agreement. They indicated demand for an affordable product with microphone functionality that still provided the requisite sound quality to serve as a good introduction to the brand in the country in question. The flashier gold accents were also a reflection of this request. It turned out that people in other countries, namely Japan, really liked the sound of the DM-380 and wanted it to be offered as well. So we opened up the DM-380 to all international markets. The DM-380 is actually not offered in mainland China, where DUNU is regarded in public opinion as a more premium brand. Our entry-level offering there, by contrast, is the DBT K10, which is a Bluetooth neckband earphone that shares the same overall acoustic setup as the DM-480. This product, however, because of regulatory issues surrounding Bluetooth modules, will not be offered internationally. We'll instead be offering a true wireless model in the latter half of next year.

    At any rate, we'll see how the DM-380 does. We're well aware of the wealth of offerings in the the sub-$100 and even sub-$50 space, and we're looking to fill out our portfolio here in the early half of next year. We're looking into developing a number of affordable multiple BA unit models that can provide head-fiers and musicians a great entry for accurate monitoring.

    We have plans to offer a special package that combines the DM-480 with the DUW-02 (the cable on the DK-2001) and an extra plug, for somewhere south of $150. This idea was conceived to try to provide people with a 'starter pack' type of experience.

    However, this package won't come immediately, because the DUW-02 is currently being manufactured in MMCX form only, and it will take a little time to re-tool and produce two-pin variants. We will try to get this out as soon as possible, however, as we feel a lot of people will want to use a reliable aftermarket cable in two-pin form that is both affordable and offers added functionality by way of its modular plugs.

    The link you provided is the actual purchase link, while the one here is the one that describes the different features of the earphone.

    Yes, pre-orders will be made available from now until the week before shipment. This is done mostly to gauge the level of interest and to prep our shipping lists.

    FYI, our website is now a functional entity that does contain official information --- it is not a third party site. We will be populating it with more and more useful information as time goes along, such as blog posts detailing our development process, our future plans, etc. Thus, our presence on AliExpress stands secondary to our website. Our online retail partners, such as Penon Audio, Shenzhen Audio (a.k.a. Leiyin Audio) follow our pricing policies and release dates, so they can't technically ship before we do.

    It should be made clear that we contracted with a third-party manufacturer to make our shells and help assemble the units. They met our requirements for overall shell quality (i.e. consistency of manufacture, shine/lustre, faceplate options, etc.) and offered an ergonomic, relatively small shell shape that was derived from a large database of ear shapes, so we were satisfied with what they could bring to the table. We were responsible for the manufacture of the driver units (our forte), the tuning, and specifying the level of quality control, as well as the sourcing of the cable and accessories.

    With lower cost units, it's not always practical to do things in-house. There are many OEM shops out there that can do very good work on one or two things, and if there is good enough communication between the OEM and brand, great things can happen. As a former ODM/OEM company, we know!

    I bought this as a gift in the related country in which the DM-380 was to be distributed. Fixed cable, mic, great comfort and sound with some added bling is a win. The user has no interest in swapping cables.The gift was gratefully received and is being extensively used.

    Yes, there is quite a bit of evidence that the life cycle cost of a fixed cable earphone is lower than that of an earphone with a replaceable cable. The cycle life of the average MMCX connector is well under 1000, with connectivity issues easily cropping up early on, especially if the user does not have experience with exchangeable cables. This was also one of the reasons why we elected to go with a non-removable cable for our entry level product. It costs us more to customize the product this way. We could've saved money by going with the default removable cables option. But we sourced a high quality OFC cable with a non-yellowing sheath instead.

    So I took a listen to the DM-380 this morning on the way to work. Shells are comfy in the ear. Blocks out noise well. It is about average but not bad. I suspect the DM-480 will do better for noise isolation since it is a solid piece of resin. The tuning I am hearing is very balanced yet does not lack for dynamics. It seems to have a very well thought out consumer type balancing. A bit more emphasis in the lows vs mids and treble. My own experience with titanium coated drivers. Stout bass, no issues there. Good amount of detail and can cover a full range of sounds with no issues.

    What is impressive about the DM-380 is how tall and full the sound is. It has some power to the sound like your hearing these though an amp. It is tuned very well in that it engages the listener. For an entry level earphone these sound fantastic and punches above their asking price IMO. These would sound good at double the price. These would make for perfect out and about earphones and sound great doing it.
