Yes, we have some really interesting earbuds arriving this summer!
Any info on these?

The Astrotec Lyra Nature Limited Edition 150Ω is a special high impedance version of the 2019 Astrotec Lyra Nature (32Ω). There have been only a few pics released thus far but more should be available after they debut this weekend at the 3rd China (Chengdu) International Headphone Show (15-16 May 2021). Here are some additional pics:
The Ks (Ksearphone - Kaisheng Technology) Temperament Bell series for 2021 so far includes two (2) known models... a new flagship model only known as "Bell-Ti Plus" and the "Ying Yang Little Bell" aka "Black & White Little Bell" which is simply the "Onmyoji 2021 Version" which was first introduced back in 2020 (Ks Temperament Bell-Ti Onmyoji; 30Ω; Aluminum Shell). Many are anxious to see what driver impedance and shell material are used for these models though it is expected to be aluminum shells for both with ~30-32Ω (Onmyoji v2021) and ~120-150Ω (Plus) drivers. They debuted at the 2021 Shanghai International Headphone Exhibition a few weeks back but will officially launch for release at the 3rd China (Chengdu) International Headphone Show this weekend 15-16 May 2021. Looking forward to seeing the specs on both. Here some pics of the PLUS:
The PISLO PXVV by ArtVano is a second generation version of their piezoelectric ceramic solid wood & resin cavity flathead earbud first introduced back three years ago the 2018 PISLO PX HIFI (31Ω @ 115dB; International "Piezoelectric" Version; ~USD $1,659!) which did come in three (3) other lower "non-piezoelectric" versions:
2018 - PISLO P7 (31Ω @ 108dB; Domestic-China Version)
2018 - PISLO PX (31Ω @ 115dB; International "Standard" Version)
2020 - PISLO 焱 Yan Black Flame Edition (31Ω @ 106dB)
The 2021 PISLO PXVV comes in two (2) piezoelectric versions: Standard or High-Impedance.
The high-impedance version comes with a dedicated piezoelectric decoding amp (Clot Audio CPWoo! - an original inverter-increasing current compensation circuit also designed by ArtVano) making it the world's first earbud with a professional-grade portable piezoelectric decoding tail. This dedicated mobile phone decoding amp was designed for dynamic headphones, especially flat-head earplugs. It is the second professional-grade portable decoder released after the CPOne / CPOne S dedicated decoding amp models were released in 2019 and CPOne Pro in 2020 (see in Spoiler down below for more info and pics).
Clot Audio CPWOO!
Adaptation interface: 3.5mm/2.5mm/4.4mm (world's first three-port decoding amp)
Support: DSD512/PCM768HKZ via AKM AK4462
Distortion: 118db
Power consumption: 55mA
Peak output: 180mw/32 ohm
Support: iOS, Android, Windows operating system
Power gain compensation circuit: The specially designed gain compensation circuit makes the decoder have better dynamic expression and image solidity when pushing the ring earplugs. It is the first decoding tail designed for moving coils.
The earbud is reported to incorporate a 9-way sound tube with 3 physical frequency channel divisions and uses copper silver alloy + silver gold-plated + single crystal silver wiring. These earbuds recently debuted a few weeks back at the 2021 Shanghai International Headphone Exhibition.
Standard version: 32 ohms
High-resistance version: 150 ohms (including 4.4mm high-resistance wiring and dedicated amp)
Standard version price: 4999
High-impedance version (including piezoelectric amp) price: 6999
I am assuming those prices are in Chinese Yuan so USD $777 and $1,100.
The older CLOT AUDIO CPOne / CPOne S / CPOne Pro design is a wood and stainless steel embedded design. The DAC can support 32 bit/384hz and does DSD 256, using the highly regarded AKK4497 custom chip. The CPOne includes 4 gain adjustments and comes standard with a gold, silver and palladium alloy cable.
