SoftEars Karma In-Ear Monitors Review
A hybrid IEM from SoftEars at $2599 in a single option, with a 10mm dynamic driver, dual bone conduction drivers, four balanced armature drivers, dual electrostatic drivers and a MEMS driver per the page. The listing text gives no impedance or sensitivity.

Our verdict
A hybrid IEM for a buyer who wants a titanium alloy housing and the five listed driver types, including bone conduction, electrostatic and MEMS drivers, at $2599. Look elsewhere if you want a stated impedance, sensitivity or cable length before paying this much, since the listing text gives none of them. The main caveat is that the sound descriptions come from the maker and were not checked here, so judge the set by the listed driver setup and your own listening.

- Skip if
- You need a stated impedance, sensitivity or cable length before buying.
The page says the SoftEars Karma continues the legacy of the Cerberus on a new acoustic platform that combines five driver technologies: a 10mm dynamic driver, dual bone conduction drivers, four full-range balanced armature (BA) drivers, dual electrostatic (EST) drivers and a MEMS driver. The housing is CNC-machined titanium alloy per the page. It is listed at $2599 as a single option, and the listing text gives no impedance, sensitivity or frequency response.
Options and pricing
There is one orderable option, priced at $2599, and the listing text gives no color, plug or bundle choice. The page says the set includes a proprietary SoftEars cable with a 7N high-purity rotary-forged OCC and silver-plated coaxial dual-layer conductor, plus UC ear tips and standard Type B ear tips. The listing text gives no plug type and no cable length, so check both before ordering.

The HeartField Astella costs $1999 and its listing text mentions electrostatic drivers. The Karma costs $2599, and its own listing names dynamic, bone conduction, balanced armature, electrostatic and MEMS drivers.
Shipping
- Methods and costs. The store's shipping page offers Standard Shipping (4PX, Yanwen or Yun Express), free for most countries, and Express Shipping (DHL Express, FedEx or SF Express) at 15-50 USD depending on the country, free for orders over 270 USD in most countries (checked 2026-11-11).
- Delivery times. It says an in-stock order ships within 3 working days, Standard takes about 2 weeks after shipping out (up to 1-3 months for some countries, and the store makes no refund for that transit time) and Express takes about 3-7 days. Festive seasons and other circumstances can change the timing.
- Taxes and fees. The buyer pays any customs, import or processing fees. The page says Standard via YunExpress is tax-inclusive for some countries, that remote areas can carry extra Express charges, and that a parcel refused or left uncollected over taxes is deducted two-way freight and may be destroyed with no refund.
- Where it ships. The page says the store can generally ship to most countries by Express and many by Standard, and to confirm Standard with the team for your country. It cannot ship to PO boxes or APO/FPO addresses and can only use Express to Hawaii. It does not name the US, Canada, the UK, Australia or New Zealand, so confirm before you pay.
- Lost parcels. If a parcel has been in transit for at least 3 months, the page offers a one-time reshipment or a full refund for orders under $50 and a 50% refund for orders above $50.
Returns and warranty
- Returns. The return page allows returning any non-customized product that is still factory sealed within 30 days of receiving it, with the buyer paying the shipping. Email [email protected] within that period; the store asks for the return to be shipped within 5 working days of the RMA instructions and in most cases processes a refund within 5 business days of inspecting it (checked 2026-11-11).
- Opened items. A product opened within the first 7 days after delivery can be returned for the price minus a restocking fee of 35% of its retail value, including when it still works properly.
- Refund or credit. The buyer can choose a refund to the original payment method (PayPal or card) or store credit; with no answer within 48 hours of confirmation the default is store credit, which can also be prioritized during promotions, final-sale events and for items 40% or more off retail.
- Not returnable. Customized products, including faceplate designs, are non-refundable, and the page says the same applies to carry cases, cables, ear tips and other accessories, "due to hygiene purposes". If one item in a package is defective, incorrect or missing, the refund or replacement covers only that item.
- Warranty. The page gives a 1-year warranty on products, excluding carry cases, ear tips and other accessories, and 3 months on cables and adapters, from the date of purchase. It covers factory defects that affect proper function, not damage from human error, negligence, accidents, dismantling, water, abuse or modification (checked 2026-11-11).
- Not covered or limited. It does not apply to items bought elsewhere (AliExpress, Amazon, local dealers and the like), prize or giveaway items, normal wear or colour change, commercial use, or items that were stolen or went missing. Coverage is limited for products 40% or more off retail, for review units and for items repaired or modified by anyone Linsoul has not authorized.
- Claims. Email [email protected] with the order number, the issue and photos and videos of the fault. The store may ask for the unit back for a replacement. It covers shipping for some defects reported within 7 days of delivery if the fault can be shown on video or photo; after 7 days the buyer ships it back. For wrong or missing items an unboxing video of the whole sealed parcel is required.
Before you buy
Linsoul says it was founded in 2016 by the Crazy HiFi team to bring Chinese HiFi makers closer to listeners worldwide, and that it now sells other makers' products alongside four brands of its own, THIEAUDIO, Kiwi Ears, ZiiGaat and Tripowin (checked 2026-11-11).

What we liked
- The page names every driver type it uses: dynamic, bone conduction, balanced armature, electrostatic and MEMS.
- The housing is listed as CNC-machined titanium alloy.
- Per the page, the MEMS driver works without a dedicated high-voltage amplifier.
- Two ear tip types are listed as included: UC tips and standard Type B tips.
- The cable is described with a 7N high-purity rotary-forged OCC and silver-plated coaxial dual-layer conductor.
Worth noting
- The listing text gives no impedance, sensitivity or frequency response, so pairing with a source cannot be judged from it.
- The listing text gives no plug type, connector type or cable length.
- Only one orderable option at $2599 is listed, so there is no lower-priced variant to choose.
- The tuning and sound descriptions are the maker's words and cannot be checked from the listing.

What we couldn’t verify
- Per the page, the sound descriptions (warm, natural, highly resolving, deep bass, smooth treble) come from the maker and were not checked here.
- Per the page, the listing text gives no impedance, sensitivity, frequency response, plug, connector or cable length.
- Per the page, the heading calls it a five-driver design while the text names five driver types with several drivers of some types, and no total driver count is given.
- We have not read an independent review of this product or the store, and the store's own ratings were not verified. We read the store's catalog description only: a specification table or image shown just on the live page was not read.
- The shipping page names no US, Canada, UK, Australia or New Zealand times or fees: its figures are general and we could not confirm them for these countries.
