After trying a USB-C to 3.5mm adapter and a different bluetooth receiver I was disappointed with sound quality and durability. The AS70 is good because it's small and easy to pair. It sounds good but IMO it's not quite as good as a direct headphone jack. I feel like you get more bass with a headphone jack when you increase the volume. I like that the receiver uses the aptX codec which sounds better than SBC. I mentioned that I use a Samsung Galaxy S20 phone and it doesn't support aptX-HD, so this could be reason why I'm not getting the full quality in sound I want. I should also mention that I switch on the "Disable absolute volume" option in the dev settings on my phone and then put the volume all the way up on the AS70. I then control the volume on my phone. I also use the Samsung Sound Assistant app. I do all of this because it helps increase the volume by smaller increments with my headphones. Overall I'm happy with this product and glad I can still enjoy decent sound quality with my headphones. Review: Does not come with audio cable. - The Avantree AS 70 is a nice device that works well. However, in order to use it as intended, you need a short length of audio cable to connect the AS70 to the headphones. While 6 ft audio cables are easy to obtain, they are too long to achieve the intended purpose of the device. It should have come with a 12-24" cable. Since it did not, I had to spend extra to order a cable. That cost me several times what it would have cost Avantree to include the cable in the box. Unlike the AS70, their Bluetooth 5.0 transmitter comes with all the needed cables in the box. ## Features - [MAKE YOUR WIRED HEADPHONES WIRELESS] Convert any wired Earphones Headphones Wired Speaker into a Bluetooth Wireless system! Free yourself from messy cables and never deal with tangled wires ever again The AS70 also features key additions like Bluetooth 5 0 aptX-HD and aptX Low Latency! - [HIGH DEFINITION BLUETOOTH SOUND QUALITY] aptX-HD is a codec capable of wirelessly transmitting 24-bit hi-res audio Meaning the AS70 is designed to transfer sound and music with ‘better-than-CD’ quality You will not hear a drop off of quality turning your wired sound system into wireless. - [WIRELESS HEADPHONE ADAPTER WITH MIC SUPPORT] This adapter has the unique ability to support and utilize your wired headphones built-in microphone This allows you to use the AS70 wired to wireless headphones adapter for better call quality and clear conversations while playing video games And in case you don’t have one use the AS70’s built-in HiFi mic. - [NO LIP-SYNC / AUDIO DELAYS] A benefit of using the AS70 Bluetooth wireless adapter is the addition of aptX Low Latency to any of your headphones or speakers Featuring aptX Low Latency which delivers sound in sync with what’s on screen so you can enjoy the freedom of wireless without detecting any lip sync audio delays. - [EXTENDED PLAYING TIME BATTERY LIFE] With a playtime of 13 Hours, you won’t have to worry about running out of power while watching videos, movies, playing video games or making a call with this AS70 Bluetooth adapter for headphones.

However, in order to use it as intended, you need a short length of audio cable to connect the AS70 to the headphones. While 6 ft audio cables are easy to obtain, they are too long to achieve the intended purpose of the device. It should have come with a 12-24" cable.

Avantree has great support. *by B***I on May 19, 2020* I originally bought an AS70 so that I could use my wireless headset with FastStream, but discovered that the device had a flaw that prevented FastStream from working. Avantee's customer support was very good and communicative, and they offered me a refund. However they said that there was no way to fix the FastStream functionality of the AS70 and that a fixed version wouldn't be available for several months. Fortunately, only a few months went by and they contacted me and let me know that an updated version of the AS70 was now available. I purchased it directly from them, they shipped it directly from China, and it arrived in just under two weeks. I've tried it out and I'm happy to say that the new version does indeed work with FastStream! The true capabilities of this device come out when you combine it with an Avantree Leaf. If you're looking to turn a wired headset into a wireless headset, and you'd like it to have acceptable audio quality and decent latency, then you can use FastStream to do it. And if all you care about is low latency audio and don't need to use a microphone, then you can use aptX-LL instead of FastStream and get better audio quality. (Note that to use FastStream, you must install a special firmware on the Leaf that prioritizes FastStream over aptX-LL.) And of course if you just want to pair it with any Bluetooth receiver, be it on your PC or phone or whatever, that works well too. Avantree gets my recommendation as a company based on how good their support has been. Even though the original device I purchased didn't work, they took good care of me and never left me hanging until my issue was resolved. (If you're purchasing an AS70 for its FastStream functionality and it's still been less than a year since I wrote this review, I recommend contacting Avantree directly and asking for a FastStream-capable AS70 rather than buying it from Amazon, as you may get one of the older units.) The only downside is that FastStream's audio quality is not great. It's acceptable, but still noticeably worse than uncompressed audio, SBC, or aptX. Some music has quite noticeable compression artifacts. This is not Avantree's fault, but rather a limitation of the FastStream codec. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kr/products/176528496-avantree-as70-bluetooth-5-0-aptx-hd-adapter-for-high](https://www.desertcart.kr/products/176528496-avantree-as70-bluetooth-5-0-aptx-hd-adapter-for-high) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-05-30*
