Portronics offers wired earphones from Rs. 275 to Rs. 899 with different features and connections.
Theta A and Kappa use 3.5mm jacks, while Theta C, Sigma, and Conch Z use Type-C.
Conch Z adds active noise cancellation, while other models focus on affordable everyday audio and calls.
Wired earphones can still suit daily calls, music, podcasts, and video when wireless features are not needed. Portronics has low-cost models with 3.5mm and Type-C ports, plus choices with larger drivers and active noise cancellation. As of September 18, 2026, these five models cover prices from Rs. 275 to Rs. 899.
The Portronics Conch Theta A costs Rs. 275 on the official site. It uses a 3.5mm Aux jack and an HD mic, so it suits phones, tablets, laptops, and other devices with a standard headphone port. Portronics also lists TPE anti-tangle material and a unique earbud design.
The 3.5mm plug avoids the need for a USB-C audio port, which can be useful with older phones, laptops, and other hardware with a standard headphone jack. The model also fits routine calls, podcasts, music, and video without extra setup.
The Conch Theta C costs Rs. 349 on Portronics. It uses a Type-C audio jack and a 14.2mm dynamic driver. The model also has a unique earbud design and TPE anti-tangle material. Portronics lists the regular price at Rs. 799 and the current offer at 56% off.
The Theta C suits devices without a 3.5mm port. Its USB-C connection removes the need for a separate audio adapter on compatible hardware. The 14.2mm driver also gives it a larger driver setup. Its Type-C port also suits recent phones that drop the older 3.5mm headphone jack.

The Conch Kappa costs Rs. 325 and uses a 3.5mm wired connection. Portronics lists a 14.2mm dynamic driver, an in-line HD mic, and TPE anti-tangle material. The current official price shows a 54% discount from Rs. 699.
The in-line mic supports calls, while the 3.5mm connector suits compatible phones, laptops, tablets, and other audio devices. Its price also sits close to the Theta A, at only Rs. 50 more. That small price gap gives the Kappa a clear place within the lower-cost range.
The earlier five-model list names this product as Conch Sigma C at Rs. 449, with a Type-C connection, a 14.2mm driver, and an HD mic. Current Portronics pages now show the product as Conch Sigma, not Conch Sigma C. The official site lists Conch Sigma at Rs. 449 against a regular price of Rs. 799, with a 44% discount.
The Sigma uses a unique in-ear earbud design and a 14.2mm dynamic driver. The Type-C port suits newer phones, tablets, and laptops that lack a 3.5mm jack. The current official page does not use the C suffix, so the name needs a check before publication.
The Conch Z costs Rs. 899. Portronics lists 12mm dynamic drivers, Type-C audio connectivity, and active noise cancellation. The official price stands at Rs. 899 against a regular price of Rs. 1,999, which marks a 55% discount.
Active noise cancellation can reduce outside sound, while the Type-C connection fits newer devices. The 12mm driver also differs from the 14.2mm drivers used by the Theta C, Kappa, and Sigma. This model therefore sits apart from the four lower-cost choices.

Portronics currently lists these models across its official audio and wired earphone pages. Some pages show direct purchase access, while others show a future-availability status. Offers can change prices, so the official product page remains the clearest price source at purchase time.
The five models cover a clear price range. The Theta A starts at Rs. 275 with a 3.5mm jack. The Kappa follows at Rs. 325 with a 14.2mm driver and an in-line HD mic. The Theta C costs Rs. 349 with Type-C audio and a 14.2mm driver. The Sigma sits at Rs. 449 with Type-C audio and a 14.2mm driver. The Conch Z reaches Rs. 899 with Type-C audio, 12mm drivers, and active noise cancellation.
For basic calls and music, the lower-cost models keep the feature set simple. Type-C users have the Theta C and Sigma, while 3.5mm users have the Theta A and Kappa. The Conch Z adds active noise cancellation at a higher price. That spread gives the Portronics wired range distinct options for different ports, budgets, and audio needs.
